ABSTRACT:
A communication system having a local network communicating with a remote network for assigning a dynamic Internet Protocol address to a communication device to enable a communication session between the communication device and an IP network The communication device sends an address request to the local network. If the local network does not selectively assign a local dynamic IP address, the address request is transmitted to a remote network to determine whether a non-local dynamic IP address from a remote pool of non-local dynamic IP addresses is able to be assigned. The communication system selectively communicates with other remote networks until a non-local dynamic IP address can be assigned to satisfy the address request. Once a non-local dynamic IP address has been assigned, the non-local dynamic IP address will be maintained for the duration of the communication session between the communication device and the IP network. If the remote pool of non-local dynamic IP addresses is able to assign a non-local dynamic IP address, then a tunnel set up request is transmitted from the local router of the local network to the remote router of the remote network to establish and OSI layer 3 tunnel to enable communications between the communication device and the IP network.
