[cisco-voip] PRI q931 CallerID

[Fedorov, Konstantin]

Hi,

I suppose that you must contact SIP PBX vendor 
And complain why PBX doesn't understand name in the SIP INFO.

Two thought.
Sending name inside Facility - possible 
Sending name inside SIP INFO - also possible.

Subject: [cisco-voip] PRI q931 CallerID

I'm running a 3640 with 12.4.13a with an NM-HDV.  We are trying to get 
callerID name working and passed via SIP to our SIP PBX.  It works on 
one of our providers, but not on the other.  When I do a "debug isdn 
q931" on the non-working link, I see that the first q931 says "Operation

= InformationFollowing" and then we immediately get another message with

"Operation=CallingName".  The problem is that this seems to mess up 
callerid with our PBX because it sends a SIP INFO message after the 
initial invite.  Does anybody know of a way to make the Cisco wait for 
half a second to send the SIP INVITE so that the callerID is in there? 
Or is there some setting on my PRI that I can enter the fix this?  Or do

I just need to call my provider and complain to them?

This is a debug from a working example:
