[cisco-voip] Codec issue?

Jon,
Those debugs are insufficient / incomplete. it might be that some things
were left out when copying/pasting or perhaps it was the way the messages
were being collected, but there's no way that the h.245 media negotiation
began with an empty terminal capabilities set and it's doubtful that the
exchange began with a sequence number of 10 for that logical channel...
value MultimediaSystemControlMessage ::= request : terminalCapabilitySet :
{
sequenceNumber 10
protocolIdentifier { 0 0 8 245 0 10 }
}
...And also, it's not normal for CUCM to send the first TCS, you have to
make it do that by changing a checkbox. (so we need the rest of the debugs,
or to figure out why they aren't here)
It seems like this debug has the h.245 for potentially more than one call,
but no complete signalling for ANY call. to really tell you what is broken,
we'll need debugs from the "SETUP" message that you see all the way up
until you see a dosconnect message with a corresponding ID after where it
says "callref"
...also, please add debug h225 asn1, debug h225 q931 , and debug cch323
events (i think?), those will help keep the debugs useful if there's more
than one call going on.
I noticed that the different endpoints involved in the provided traces seem
to have different max sizes for their g.711 payloads, which is curious, but
without the Open Logical Channel messages (missing from your debug) no one
can tell what codecs the sides are ACTUALLY trying to use.
