ABSTRACT:
Call progress analysis is performed in a telephone system employing different in-band signaling plans are used. From address information for a call destination in a call initiation message, it is determined which type of in-band signaling plans is utilized by equipment associated with the call destination, for example by examining country codes in a dialed telephone number. Based upon the determined signaling plan type, a corresponding type of call progress analysis resource is selected and allocated for use with the call. The analysis resource may include a digital signal processor (DSP) programmed with an analysis routine tailored to the determined signaling plan. The DSP may be pre-programmed with such a routine or may be loaded at call time with analysis parameters appropriate to the signaling plan. The telephone system may employ a packet network and packet-based telephony transmission, a media gateway controller or a Session Initiation Protocol (SIP) proxy server, an a media server. A telephone network employing more traditional time-division-multiplexed (TDM) based media transmission may also be utilized.
