[cisco-voip] Facility IE cnam delivery and SIP

[Brian Meade (brmeade)]

It looks like you're received that message from the carrier in response to sending a STATUS.  I'm guessing the carrier switch is hitting something like CSCsj03558.  Here's a snippet of the logs from that bug:

" May  7 10:26:16.032 EDT: ISDN Se1/0:23 Q931: RX <- STATUS pd = 8  callref = 0x02
A0 
	Cause i = 0x83E203 - Message not compatible with call state or not imple
mented 
	Call State i = 0x07"

Brian,

     Yes, it seems to be for Facility messages, there's a snippet below. It spits a similar error to what is listed in that bug when set as 5ESS. If I set it to NI then it seems to understand these messages and it operates properly, but it stops working after some time so there are other incompatibilities. It does work as MGCP backhauled to a UCM so it would appear the carrier's signaling is valid. This is on a 2921 running 15.1(4)M4. I had not upgraded past this point as I had seen a number of bugs appear regarding ISDN PRI calls and crashing, and everything is working otherwise at the moment.
