System and method for performing signaling-plan-specific call progress analysis

A telephone system providing analog call progress analysis, comprising:

• a packet network operative to provide packet-based transmission of media and signaling traffic;
• a first node coupled to the packet network, the first node being operative to perform a routing function, the routing function determining, from address information for a call destination contained in a call initiation message received from a call initiator coupled to the packet network, which of different types of in-band signaling plans is utilized by equipment associated with the call destination;
• and
• a second node coupled to the packet network, the second node being operative to perform a media processing function, the media processing function selecting, based upon the signaling plan type determination, a corresponding type of call progress analysis resource and allocating the selected call progress analysis resource to the call.

A telephone system providing analog call progress analysis, comprising:

• a signaling network operative to provide transmission of call signaling traffic;
• a media network operative to provide time-division-multiplexed based transmission of call media;
• a controller coupled to the signaling network, the controller being operative to perform a routing function, the routing function determining, from address information for a call destination contained in a call initiation message received from a call initiator, which of different types of in-band signaling plans is utilized by equipment associated with the call destination;
• and
• a media processing node coupled to the media network, the media processing node being operative to perform a media processing function, the media processing function selecting, based upon the signaling plan type determination, a corresponding type of call progress analysis resource and allocating the selected call progress analysis resource to the call.
