Abstract
In one embodiment, a service node will recognize an attempt to initiate a call from a first terminal to a second terminal, and automatically provide information to media clients associated with the first and second terminals such that a media session can be readily established between the media clients in association with the call. The service node may be configured to interact with telephony switches that support the first or second terminals, directly or indirectly via a signaling adaptor. In a second embodiment, the service node will recognize an attempt to initiate a call and will route the call to a gateway, which is controllable by the service node. Once the call is sent to the gateway, the service node may provide instructions to the gateway for routing or otherwise processing the call.
