DTMF tones not registerring for some SIP outbound calls

[Unifiedtt]

calls work for all external calls going over the SIP

when the autoattendant is playing and i enter an extension, it does not register the tones.

whats strange is that i called another external number and it works for that number

HELP?

Are you using CUBE ? Please post the config and debug outputs from the following commands

hi, thank yu for the reply.

i am new to the VOICE environment so i may not know all the terminology used. I am not sure if I am using cube but the system we have is an old UC520  system. i have attached the logs you requested and i look forward to your help

thanks

So what exactly is the issue - external calls only or both internal and external calls dont detect DTMF?

Looks like this may be an issue with your dial-peer config, can you post your config as well.

external calls calling into our system works fine.

when we make an an external call from the cisco phones to another company, when our call conects to their autoattendant and we try to enter an extension number , it does not recognize the key and the autoattendant continues to play.

below is the configs

dial-peer voice 1020 voip
 translation-profile outgoing PSTN_Outgoing
 preference 1
 destination-pattern 9[234678]......
 session protocol sipv2
 session target sip-server
 voice-class codec 1
 voice-class sip dtmf-relay force rtp-nte
 dtmf-relay rtp-nte
 dtmf-interworking rtp-nte
 ip qos dscp cs5 media
 ip qos dscp cs4 signaling
 no vad

Do you have an inbound voip dial-peer configured on your router?  It not, it will be matching dial-peer 0 when CUCM sends a call to it and could be causing you issues.  Your inbound voip dial-peer could look something like this:

dial-peer voice 1 voip

incoming called-number .

session protocol sipv2

voice-class codec 1

dtmf-relay rtp-nte

no vad

Let me know if that helps any.

Thanks,

Brandon
