System and method for establishing and maintaining a voice over internet protocol connection between wireless devices

A method of establishing a connection between communication devices via a network, the method comprising:

• receiving a first communication device identifier identifying a first communication device communicatively coupled to a first terminal;
• receiving a request to establish communication between the first communication device and a second communication device;
• making a determination, using one more processors, whether the second communication device is reachable by a second terminal over a second data link based on information stored in a communication device register;
• and
• based on the determination that the second communication device is reachable, enabling establishment of the communication between the first communication device and the second communication device by transmitting a network address of one terminal to another terminal of the first and second terminals, prior to forwarding a call from the first terminal to the second terminal, to enable the first terminal and the second terminal to establish a network connection therebetween using the transmitted network address.

A non-transitory machine-readable storage medium comprising instructions, which, when implemented by one or more processors, perform operations comprising:

• receiving a first communication device identifier identifying a first communication device communicatively coupled to a first terminal;
• receiving a request to establish communication between the first communication device and a second communication device;
• making a determination, using the one more processors, whether the second communication device is reachable by a second terminal over a second data link based on information stored in a communication device register;
• and
• based on the determination that the second communication device is reachable, enabling establishment of the communication between the first communication device and the second communication device by transmitting a network address of one terminal to another terminal of the first and second terminals, prior to forwarding a call from the first terminal to the second terminal, to enable the first terminal and the second terminal to establish a network connection therebetween using the transmitted network address.
