Hello
I am sending call from a Nextone SBC to an AS5400. The AS5400 is routing the call but not putting any CDN into the ISDN setup message even though the incoming invite has the TO header populated with the number
I compared a good call to a bad and what I did notice is that the bad calls TO header looks like this coming into the 5400
To: 011861085208666<sip:011861085208666@38.117.159.235:5060>
A good call looks like this
To:<sip:011861085208666@38.117.159.235:5060>
Could the 5400 have a problem with the double format ? Has anybody seen this before ?
Here is the trace from the 5400 and you notice the CDN field is not populated in the outgoing ISDN setup.

I think there should be a space before < in the below, typo ?
To: 011861085208666<011861085208666> 011861085208666>

Actually, it is not necessary: (http://tools.ietf.org/html/rfc3261#section-20.10) There may or may not be LWS between the display-name and the "<".

There is a space
That was a typo
Here is what my dial peer looks like. Can figure out why the 5400 is not translating this tothe ISDN side and sending a NULL CDN to my gateway
dial-peer voice 28 pots
destination-pattern 011861085208666
port 1/0:28:D

Does 'debug ccsip error' reveal anything?
11-28-2007 08:50 AM
nothing shows up on the degub ccsip error or debug isdn q931 error
The thing is this TO header format is being sent out to a SIP peering provider of mine and they are not having an issue with it. Only the 5400. It does not populate a CDN parameter in the ISDN setup message to my PSTN switch

Which exact IOS are you using ?
11-28-2007 01:30 PM
I found the issue
This is what my dial peer looked like
dial-peer voice 28 pots
shutdown
destination-pattern 011861085208666
port 1/0:28:D
Here is what is looks like now
dial-peer voice 28 pots
shutdown
destination-pattern 0118610
port 1/0:28:D
Now the call works ! ?? The CDN is being placed into the ISDN setup properly
Bug ?
Is there a digit timer command I am missing here ?
Cisco IOS Software, 5400 Software (C5400-IS-M), Version 12.4(16), RELEASE SOFTWARE (fc1)

Well, pots DP by default absorbs digits matched in destination-pattern, so configured like it is now, it should send 85208666 as called number.
This behavior can changed with "forward-digits" and "digit-strip" commands.
Hope this helps, please rate post if it does!
