Hi all,
we have recently terminated sip trunk on one of our customers site there seems to be problem with Unity as AA and voicemail is not functioning properly.
The AA has number 2293100, extensions are 4 digits in range of 2293100-229399. I have to put complete number 2293100 for AA to work but it does not answer i tried looking at the logs but i could not understand anything. The same is with the Voicemail the calls are not getting forwarded to voicemail once the cfna timer expires.
When i bring it back to analog lines everything seems to be working fine.
I have attached logs for cme and cue.
this is 3800 series router with 12.4 ios and 4.x cme.
Solved! Go to Solution.

Mohd,
After more investigation, it look slike I have see what the problem is.
Cisco CUBE doing SIP-SIP does not support DTMF translation from SIP-Notify to RFC2833 (rtp-nte)
What this mean is that you cant call the CUE AA directly.
So I will suggest you do the following:
1. On your inbound dial-peer from your ITSP, make sure you have only rtp-nte as your dtmf-relay
2. Then on your outbound dial-peer to CUE make sure its sip-notify as you have now
3. Make a test call to a phone, ensure the call is forwarded to voicemail....Does that work? If that work then great
4. Create an extension in CME with CUE AA number. On the number do a CFDWALL to CUE (so replace the AA pilot number in CUE with a new number and forward from CCME AA pilot number to this number
5. Finally cponfigure this on your gateway..
voice service voip
no supplementary-service sip moved-temporarily
Let me know what the outcome is...
NB: if it works, then great. But you may not be able to enter any dtmf digits because we still need to adjust your config for this provider on entering dtmf digits...

Hi Aoklawon,
My sip provder at last responded back with a reply that it is a codec issue and we are not sending PCMA/8000 G711ALAW request that is why they are not responding pls have a look at the debug logs from their side i could understand none of it.
Can u tell me is the transcoding configuration done properly as the cue supports only g711ulaw??

Malik,
I dont know what your provider is talking about. I believe what they are talking about is not correct. Why did I say so..Because in the invite sent by your provider G711ulaw was advertised...Also I dont know any SIP provider that does not support G711ulaw.
Here is a proof. (i have underlined the codecs advertised by them) Take it back to them and tell them that they advertise G711ulaw

CUE will only support G711ulaw. This is the codec it will advertise when it responds with a 200 ok SDP. I dont think we can change this by trannscoding..
In the meantime while you respond to them, please try and add this command and test again...

Then add it to this dial-peer.. ( i assume you still have it in your config)
