AS5400 problem

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.

Re: AS5400 problem

I think there should be a space before < in the below, typo ?

To: 011861085208666<011861085208666>

Re: AS5400 problem

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 "<".

Re: AS5400 problem

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

Re: AS5400 problem

Does 'debug ccsip error' reveal anything?

Re: AS5400 problem

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

Re: AS5400 problem

Which exact IOS are you using ?

Re: AS5400 problem

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)

Re: AS5400 problem

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!
