HI Alok. Very subtle in IWF Debug log from X6. You wont see this in X7 as its fixed, and IWF can pick this up.
IWF builds caps on SIP leg of the call:

------------------------------
After receiving CAPS on h323 leg, IWF builds caps to send back to H323 leg. Here, for packetization mode 1, sends the following from IWF to the parser:
capabilityTableEntryNumber 7,
capability receiveVideoCapability : genericVideoCapability :
{
capabilityIdentifier standard : { 0 0 8 241 0 0 1 },
maxBitRate 3840,
collapsing
{
{
parameterIdentifier standard : 41,
parameterValue booleanArray : 64
},
{
parameterIdentifier standard : 42,
parameterValue unsignedMin : 64
},
{
parameterIdentifier standard : 6,
parameterValue unsignedMin : 6666667
},
{
parameterIdentifier standard : 7,
parameterValue unsignedMin : 647
}
}
}
},
----------------------------
Parser can't encode it, and if fails:

}
}
},

Call fails as the iwf sends release to H323 leg.
If they are interworking on X6, won't work here. They need to update to X7 to resolve the iwf issue present. Hope this helps.
