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
                  }
                }
