Description (partial)
Symptom: When an incoming H.245 Terminal Capability Set message has a standard G.722.1 genericAudioCapability without collapsing parameter values, there is a ccm core. The collapsing parameter of G.722.1 in the TCS is mandatory. Hence this is a non-compliant implementation and the other side has to send the collapsing parameters for the G.722.1. Conditions: Incoming TCS has a standard G.722.1 genericAudioCapability without collapsing parameter values. Example: capability receiveAudioCapability : genericAudioCapability : { capabilityIdentifier standard : { x x x x x x }, maxBitRate 24000 } whereas expected is of the form below: capabilityIdentifier standard : { x x x x x }, maxBitRate 248, collapsing { { parameterIdentifier standard : 0, parameterValue unsignedMin : 1 }, { parameterIdentifier standard : 2, parameterValue logical : NULL }, { parameterIdentifier standard : 4, parameterValue unsignedMin : 0 } }
