I tired a combination to add

asherif82 · ‎09-06-2015

We have that Scenario when trying to call Unity Connection, Cisco WebEx or any service that requires DTMF ,it does not sense the digits. the call flow is as follow:

SIP ISP-->CUBE (Inbound Dial-peer)--->CUBE(outbound Dial-peer)---->Unified CM

I have attached the configuration as well as the debug ccsip message .As far as I can see the SIP is sending dtmf 96 rtp-nte however the call manager is responding with dtmf 101 rtp-nte. I tried to configure "rtp payload-type cisco-codec-fax-ind 102" and "rtp payload-type nte 96" under dial-peers inbound and outbound but with no luck. Also,I tried on inbound to be dtmf 96 and on outbound to be 101 hardcoded but with no hope.

So guys, what do I Miss here?

Mohammed al Baqari · ‎09-06-2015

Hi,

It sounds to me that you are using SCCP integration with applications like cuc while you are using RTP-NTE which won't work.

In the dialpeer facing cucm change dtmf relay to SIP notify.

The second option is to deploy MTP which will handle the translation of DTMF RTP.

I suggest to try SIP notify for simplicity

asherif82 · ‎09-06-2015

I tired a combination to add an MTP on SIP trunk and also deployed dtmf-relay sip-notify but with no luck.

The strange thing is that I'm adding what it looks like in the debug which is nte 96 but it refuses to accept it.

Any ideas guys?

James Hawkins · ‎09-06-2015

Are you sure that the call is matching the inbound dial peer you think it is?

I had a similar issue and it turned out that the inbound call leg was matching the default dial peer rather than the one I assumed it was.

asherif82 · ‎09-07-2015

Hi,

Well I'm matching dial-peer 2 for incoming and dial-peer 4 for outgoing,I don't think I'm matching dial-peer 0.

I have attached the debug voip dialpeer and show call active voice br

Mohammed al Baqari · ‎09-07-2015

Hi,

Your call is using G729r8 but your MTP is configure for G711ulaw. Please correct this config and test again.

dspfarm profile 3 mtp  
 codec g729r8

If didn't working share the output of show call active voice br, show sccp and show sccp conn.

asherif82 · ‎09-07-2015

Hi,

I have changed dsp profile 3 as you mentioned above and made sure it registered to the Unified CM but it did not work.

below is the show commands :

I have tried adding MTP on the SIP Trunk but with no luck.

what else can be done?

Mohammed al Baqari · ‎09-08-2015

Looks that you changed your config. Now the call using PID 2 & 4 is using G711alway which is different from the original config and previous output. Also, MTP isn't being inserted by IOS.

You need to stick on one config and post the latest information.

Also, you need to make sure that MTP is assigned to MRG, MRG assigned to MRGL, MRGL is assigned to SIP trunk.

asherif82 · ‎09-08-2015

You are right I have changed the configuration little bit. I'll revert it back using MTP check box on the SIP trunk with g729 codec and mtp profile has g729r8.Also the MTP is registered on the Unified CM and located in the DP assigned to the SIP trunk.

Hi,

So with this config, is DTMF working?

If not, can you share the output of 'deb voip rtp session named-event' when you press DTMF digits?

asherif82 · ‎09-13-2015

Hi,

The problem finally solved. It was related to network as UCS servers hosting unity connection is connected to Nexus 9k which has a bug in the software that remove the DTMF from rtp packet . After upgrading it the problem resolved.

Muhammad Aamir Ubaid · ‎02-11-2016

Hi Ashraf,

We are facing same issue after migrated all UCS server on the Nexus 9K the DTMF is not working . I need your help to resolve this issue. could you tell which software version you upgraded in order to resolution.

I need the prompt reply from you. currently i am using the below software in 9K.
