Signaling Architecture Sample Clauses

Signaling Architecture. The general VoIP signaling architecture is based on a Q.931 backbone running between end-points, with conversion of local signaling semantics to Q.931 within each end-point. Physical interfaces and associated signaling schemes (e.g. pulse dialing, PRI) have local significance only - this preserves the any-to-any connectivity nature of VoIP. This concept is illustrated by example in Figure 1. Here, both the Internet telephone and gateway service elements provide termination of their local signaling format and semantic conversion to the Q.931 backbone. Providing any-to-any connectivity also precludes concepts such as CAS??telemetry.
