This disclosure relates generally to session initiation protocol (SIP) trunking to perform wireline to cellular and cellular to wireline signal conversions. More specifically, this disclosure relates to facilitation of SIP trunking via a router with a cellular modem, a mobility network, and a virtual Internet gateway.
SIP trunking is a voice over internet protocol (VoIP) and streaming media service by which Internet telephony service providers (ITSPs) deliver telephone services and unified communications to customers equipped with SIP-based private branch exchange (IP-PBX) and unified communications facilities. Unified communications software applications provide voice, video, and other streaming media applications such as desktop sharing, web conferencing, and shared whiteboard.
The architecture of SIP trunking provides a partitioning of the unified communications network into two different domains of expertise: 1) private domain, which is a VoIP solution realized at a customer's home that takes advantage of phone and unified communication services; and 2) public domain, which is a full VoIP access solution to the public switched telephone network (PSTN)/public land mobile network (PLMN) property and responsibility of the ITSP that provides phone service. The interconnection between the two domains must occur through a SIP trunk. The interconnection between the two domains, created by transport via an Internet protocol (IP), involves setting specific rules and regulations as well as the ability to handle some services and protocols that fall into the well-defined name of SIP trunking.
Although the ITSP is responsible to the applicable regulatory authority regarding law obligations of the public domain, the private domain is not subject to particular constraints of law, and may be either the responsibility of the ITSP, the end user (enterprise), or of a third party who provides the voice services to a company. Other contextual information may become further apparent upon review of the following detailed description.
Non-limiting and non-exhaustive embodiments of the subject disclosure are described with reference to the following figures, wherein like reference numerals refer to like parts throughout the various views unless otherwise specified.

A mobility cloud can have several functionalities. A private broadcast exchange (PBX) wireless-modem can send unique credentials (user-ID and service-selector) of the PBX to the mobility cloud, which can facilitate several functionalities. It can increase overall security by checking the User-ID credentials to establish the right of a particular user to use the associated service-selector. If the check is successful, meaning that a particular PBX is allowed to use the associated service-selector, then an IP address from a specific range of IP addresses, which is identified by the service-selector, can be allocated to the PBX router. The Mobility cloud allocated IP address, being part of a specific IP address range, can increase overall security by allowing a firewall situated at the virtual internet gateway (VIG) to allow a particular voice signal through. If the voice signal has an IP address not belonging to an IP address range that is associated with the PBX, then that particular stream can be blocked and not allowed through.
The service-selector credential can also be utilized to determine how the wireless signal will be routed within the mobility network. The service selector can select an egress point (interface) from the mobility network to the Internet. The service-selector can establish a logical wireless signal path from the PBX wireless-modem to the selected egress point, wherein the logical path can comprise self healing and re-routing capabilities that increase the overall reliability of the wireless network. This path can tolerate various failures in the mobility network and still maintain service. Therefore, the initial processing can authenticate the user (i.e. PBX) and authenticate the user's access to the specified service-selector. Also, the service selector can establish a logical path from the PBX to the mobility cloud egress interface.
The PBX wireless-modem can convert the wireline signal to a wireless signal to be sent to the mobility cloud. The wireless signal can then be routed through the mobility network to a pre-determined egress point. That egress point can be determined by the service-selector credential sent earlier by the PBX. At the egress point, the mobility cloud can convert the wireless signal back to a wireline signal and send the wireline signal to the VIG. The egress point can be unique in the mobility cloud, wherein a particular stream can be forced to exit thru a particular interface. This, in turn, can increase overall security as the voice signal can be directed to reach a particular VIG (out of a set of VIGs) thus not allowing the voice signals from different PBXs (enterprises) to be mixed.
Utilizing a configurable network router in conjunction with a cellular network of a mobility service provider identity can improve SIP trunking efficiencies. Internet protocol addresses can be utilized based on secure private branch exchange access to the mobility service provider identity. Described herein are systems, methods, articles of manufacture, and other embodiments or implementations that can facilitate usage of SIP trunking over a cellular network. The various embodiments can be implemented in connection with any type of device with a connection to a communications network (e.g., a wireless communications network, the Internet, or the like), such as a mobile handset, a computer, a handheld device, or the like.
SIP trunking service can be provided over cellular connectivity including, but not limited to, long-term evolution (LTE). Although wireline connectivity can be provided over a cellular network, trunk side connectivity can be provided over LTE. However, SIP trunking service over wireline connectivity can suffer from long and difficult recovery in disaster recovery scenarios and extended implementation times. Implementing SIP trunking over LTE can facilitate more efficient deployment and a more efficient recovery. By mobilizing the SIP trunk (using cellular connectivity) the recovery times and implementation times can be reduced.
To support this approach a router, including but not limited to a NetGate router, with an LTE modem can establish connectivity from a mobile service provider (mobility network) to a private branch exchange network. The router can support multiple local area network (LAN) ports via an Ethernet connection. An Internet protocol private broadcast exchange (IP-PBX) can communicate with one LAN or sub-network and IP devices including, but not limited to, telephones and can communicate with another LAN port. The router can support cellular modem devices and store data related to all of the sub-networks that are communicating with the router. Although SIP signaling is done by the IP-PBX in IP telephony, the data-flow (voice over IP) can be directed to a different destination such as plain old telephones or IP phones. The router, via a cellular modem, can either originate calls or accept calls. Services can also be designed specifically for call origination only. For example, if an application queries a database, then a call origination only mode of operation can provide additional security. However, both IP streams, signaling and data can arrive over the same IP security tunnel to the router. Thus, the router can send specific IP data to selected destinations.
Additionally, the router can manage the IP devices remotely. Router management of the IP devices can include, but is not limited to, provisioning of the IP devices, updating the IP devices, adding service to the IP devices, and/or removing service from the IP devices. Furthermore, a router console can be used for troubleshooting and local management. For example, the router console can allow for viewing of log files that normal users do not have access to.
The mobility network can enable data, such as voice over IP, to travel through multiple selected paths, thus providing redundancy. The redundancy can improve the overall network service reliability. The system can provide enhanced security measures including, but not limited to, selecting a range of IP addresses. The IP-PBX and all its subtending IP devices can be the only devices that can use the data path as a closed user group. As another security measure, the system can also check to validate that a user from the PBX is allowed to use cellular services.
The cellular network can allocate IP addresses to devices that want to use its services. A range of IP addresses can be allocated to a specific enterprise. When a device, which belongs to that specific enterprise, requests a service, the device can receive an IP address from a selected range. This methodology can increase security because the firewall, at the virtual internet gateway (VIG), can know to only allow IP streams with IP addresses from the specific range. For example, once a cellular modem is powered-up, credentials including, but not limited to, a user identification and/or a service selector, can be sent to the wireless provider's mobility network as an access point name (APN). The service-selector can communicate to the mobility network to select the range of the IP addresses to be allocated. However, before the IP address is sent to the modem, the mobility network can check the user identification to ensure that the user is indeed entitled to use the service selector. Once all of the security checks are complete, the IP address of the correct range can be sent to the modem.
SIP trunking over LTE can also provide higher security by encrypting the cellular path via the cellular modem. The cellular modem, which can be a component of the router, can be provisioned with credentials that allow it to connect to the mobility network. Once the credential checks are performed and determined to be successful, one or more IP addresses, set by the mobility network provider, can be allocated to the cellular modem. These IP addresses can belong only to the cellular modem. Once the cellular modem receives the IP addresses, the cellular modem can establish a packet data protocol tunnel to the mobility network. Thus the data, from this point, can be sent through the packet data protocol tunnel. An IPSec (IP security) tunnel can also facilitate secure communication from the router to the mobility network. The IP security tunnel can begin at the router, which can be before the cellular modem, and can end at the VIG of the service provider.
The VIG can serve as the entry point from the mobility provider's network into the Internet. Additionally, the VIG can serve as the termination point of the IP security tunnel, which can exist between the router and VIG. Data passed between the router and the VIG can be encrypted. The VIG can provide customers with data services as opposed to voice services. The VIG can also be aware of selective data flows that arrive from pre-determined routers and can know to provide service only to specific routers that are pre-provisioned with the mobility provider's data service. The service, connecting IP-PBXs to the mobility provider, although voice-based, can be facilitated by the router to VIG connection. Thus, a private branch exchange network can increase topology reliability and maintain wireline and wireless connections simultaneously.
An outbound call from the IP-PBX can initiate from a subtending phone, where the IP-PBX can call a PSTN. The request can be sent by the IP-PBX to the router. The router can convert the request to cellular data and send it to a mobility cloud. The mobility cloud can convert the cellular data back to wireline data and send the request to the VIG. The VIG can then send the request via a permanent virtual connection (PVC) to a Voice over IP (VoIP) cloud which determines that the call is destined for a PSTN phone and convert it to PSTN format of signaling system no. 7 (SS7) and send it to the right network. The VoIP can comprise a business VoIP or the like.
An inbound call to the IP-PBX can be initiated from a PSTN phone call to an IP phone. A request can be sent to a VoIP network cloud, which can convert the phone call from SS7 to IP. The SIP/IP request can be sent to the VIG, and the VIG can send it to the mobility network, which converts the wireline signal data to cellular signal data and sends it to the PBX router. After receiving the request, the PBX router can convert the cellular signal data back to wireline signal data and send it to the IP-PBX. The IP-PBX can then send the request to a device associated with the PBX network.
In one embodiment, described herein is a system that can facilitate a router receiving first wireline signal data from a device associated with a private branch exchange device. The router can convert the first wireline signal data to cellular signal data and then send the cellular signal data to a virtual Internet gateway device via an Internet protocol security tunnel. The system can also facilitate a storing of Internet protocol address data. The system can include a display component and one or more servers in a cloud-computing environment that can store information about cellular data and/or Internet protocol addresses.
According to another embodiment, described herein is a method for converting cellular signal data to wireline signal data to be carried by a wireline to a user device associated with a private branch exchange device. Prior to converting the cellular signal data, the cellular signal data and Internet protocol address data can be received by a wireless router.
According to yet another embodiment, an article of manufacture, such as a computer readable storage medium or the like, can store instructions that, when executed by a computing device, can facilitate receiving cellular signal data from a virtual internet gateway device and converting the cellular signal data to wireline signal data. The wireline signal data can then be sent to another device using an Internet protocol. These and other embodiments or implementations are described in more detail below with reference to the drawings.

The mobility network 308 can allocate IP addresses to devices that want to use its services. A range of IP addresses can be allocated to the PBX network 300. When a device, which belongs to the PBX network 300, requests a service, the device can receive an IP address from a selected range. When the modem associated with the PBX router 304 is powered-up, credentials including, but not limited to, a user identification and/or a service selector, can be sent 306 to the wireless provider's mobility network 308 as an access point name (APN). The service-selector can communicate to the mobility network 308 which range of the IP addresses can be allocated. However, before the IP address is sent to the modem, the mobility network 308 can check the user identification to ensure that the user is indeed entitled to use the service selector. Once all security checks are complete, the IP address of the correct range can be sent 322 to the modem. These IP addresses can belong only to the cellular modem. Once the cellular modem receives the IP addresses, the cellular modem can establish a packet data protocol tunnel to the mobility network 308.
After wireline signal data has been converted to cellular signal data by the PBX router 304, the cellular signal data can then be sent 324 through the packet data protocol tunnel. The mobility network 308 can send 310 the cellular signal data over the Internet 312, which will convert the wireless signal to wireline signal and send 314 the wireline signal data to a virtual internet gateway 316 associated with the mobile service provider identity. The virtual Internet gateway 316 can then decrypt the wireline signal data and send 318 the decrypted wireline signal data, which is representative of the original wireline signal data, to a router 320 associated with the service provider.

The interface 1224 for external drive implementations includes at least one or both of Universal Serial Bus (USB) and IEEE 1294 interface technologies. Other external drive connection technologies are within contemplation of the subject innovation.
The drives and their associated computer-readable media provide nonvolatile storage of data, data structures, computer-executable instructions, and so forth. For the computer 1200 the drives and media accommodate the storage of any data in a suitable digital format. Although the description of computer-readable media above refers to a HDD, a removable magnetic diskette, and a removable optical media such as a CD or DVD, it should be appreciated by those skilled in the art that other types of media which are readable by a computer 1200, such as zip drives, magnetic cassettes, flash memory cards, cartridges, and the like, can also be used in the exemplary operating environment, and further, that any such media can contain computer-executable instructions for performing the methods of the disclosed innovation.
A number of program modules can be stored in the drives and RAM 1212, including an operating system 1230, one or more application programs 1232, other program modules 1234 and program data 1236. All or portions of the operating system, applications, modules, and/or data can also be cached in the RAM 1212. It is to be appreciated that the innovation can be implemented with various commercially available operating systems or combinations of operating systems.
A user can enter commands and information into the computer 1200 through one or more wired/wireless input devices, e.g., a keyboard 1238 and a pointing device, such as a mouse 1240. Other input devices (not shown) may include a microphone, an IR remote control, a joystick, a game pad, a stylus pen, touch screen, or the like. These and other input devices are often connected to the processing unit 1204 through an input device interface 1242 that is coupled to the system bus 1208, but can be connected by other interfaces, such as a parallel port, an IEEE 2394 serial port, a game port, a USB port, an IR interface, etc.
A monitor 1244 or other type of display device is also connected to the system bus 1208 through an interface, such as a video adapter 1246. In addition to the monitor 1244, a computer 1200 typically includes other peripheral output devices (not shown), such as speakers, printers, etc.
The computer 1200 can operate in a networked environment using logical connections by wired and/or wireless communications to one or more remote computers, such as a remote computer(s) 1248. The remote computer(s) 1248 can be a workstation, a server computer, a router, a personal computer, portable computer, microprocessor-based entertainment device, a peer device or other common network node, and typically includes many or all of the elements described relative to the computer, although, for purposes of brevity, only a memory/storage device 1250 is illustrated. The logical connections depicted include wired/wireless connectivity to a local area network (LAN) 1252 and/or larger networks, e.g., a wide area network (WAN) 1254. Such LAN and WAN networking environments are commonplace in offices and companies, and facilitate enterprise-wide computer networks, such as intranets, all of which may connect to a global communications network, e.g., the Internet.
When used in a LAN networking environment, the computer 1200 is connected to the local network 1252 through a wired and/or wireless communication network interface or adapter 1256. The adapter 1256 may facilitate wired or wireless communication to the LAN 1252, which may also include a wireless access point disposed thereon for communicating with the wireless adapter 1256.
When used in a WAN networking environment, the computer 1200 can include a modem 1258, or is connected to a communications server on the WAN 1254, or has other means for establishing communications over the WAN 1254, such as by way of the Internet. The modem 1258, which can be internal or external and a wired or wireless device, is connected to the system bus 1208 through the serial port interface 1242. In a networked environment, program modules depicted relative to the computer, or portions thereof, can be stored in the remote memory/storage device 1250. It will be appreciated that the network connections shown are exemplary and other means of establishing a communications link between the computers can be used.
The computer is operable to communicate with any wireless devices or entities operatively disposed in wireless communication, e.g., a printer, scanner, desktop and/or portable computer, portable data assistant, communications satellite, any piece of equipment or location associated with a wirelessly detectable tag (e.g., a kiosk, news stand, restroom), and telephone. This includes at least WiFi and Bluetooth™ wireless technologies. Thus, the communication can be a predefined structure as with a conventional network or simply an ad hoc communication between at least two devices.
Wi-Fi, or Wireless Fidelity, allows connection to the Internet from a couch at home, a bed in a hotel room, or a conference room at work, without wires. Wi-Fi is a wireless technology similar to that used in a cell phone that enables such devices, e.g., computers, to send and receive data indoors and out; anywhere within the range of a base station. Wi-Fi networks use radio technologies called IEEE 802.11 (a, b, g, etc.) to provide secure, reliable, fast wireless connectivity. A Wi-Fi network can be used to connect computers to each other, to the Internet, and to wired networks (which use IEEE 802.3 or Ethernet). Wi-Fi networks operate in the unlicensed 2.4 and 5 GHz radio bands, at an 11 Mbps (802.11a) or 54 Mbps (802.11b) data rate, for example, or with products that contain both bands (dual band), so the networks can provide real-world performance similar to the basic 10BaseT wired Ethernet networks used in many offices.
