Abstract
An invention is disclosed that includes a Foreign Agent that supports Mobile IP and is configured to enable a node visiting the Foreign Agent to send IP packets including voice information via an IP address obtained from an H.323 gateway. This is accomplished, in part, by sending an agent advertisement identifying an H.323 gateway on the foreign network. A packet is received from the node, where the packet is addressed to the H.323 gateway and requests an IP address associated with a destination. A packet including the requested IP address is forwarded to the node. An IP packet addressed to the IP address and including voice information may then be received from the node. A node visiting the Foreign is capable of sending IP packets including voice information and receives an agent advertisement identifying an H.323 gateway on a foreign network associated with the Foreign Agent. The node sends a packet addressed to the H.323 gateway, where the packet requests an IP address associated with a destination. A packet including the requested IP address is received by the node. The node may then send an IP packet addressed to the IP address and including voice information from the node.
