Having issues with DTMF transfer on UC520 configured with SIP Trunk.

All,

I am having an issue with my dtmf not recognizing when a number is pressed on a phone. We have the ability to transfer phone calls to our operator if the recipient presses 1. However, when the recipient presses 1 the call is not transferred and eventually the call is dropped. I have turned on debugging for voip ccapi inout ; ccsip messages ; and voip ftp session named-event. I have attached the debug logs. Any help would be greatly appreciated.

Re: Having issues with DTMF transfer on UC520 configured with SI

Changing the CUE DTMF is so you don't break DTMF for CUE outcall scenarios, since the dial-peer that will be matched for these calls will now expect RTP-NTE.

Re: Having issues with DTMF transfer on UC520 configured with SI

Well, If we accept that the three common ways of transporting DTMF are:

1. Named telepone events - Inband RTP-NTE

2. SIP Info

3. in audio (we're ignore this one)

then we need to look to see what isn't working.

There are no SIP INFO messages anywhere, so let's concentrate on rtp-net

1. The Outgoing call to the SIP trunk INVITE looks like this:

INVITE sip:1XXXXXXXXXX@sipconnect.dal0.cbeyond.net:5060 SIP/2.0

and the 200 OK of this call like this:

so the outgoing call agrees on RTP-NTE

So we have no negotiation of RTP-NTE between the phone and your Cisco

I would suggest looking at the incoming dial-peer for the phone and making sure it includes dtmf-relay rtp-nte.

SIP INFO isn't enabled, and we're not transcoding audio, so inband audio is no good to us,

Re: Having issues with DTMF transfer on UC520 configured with SI

Adam,

That is a great help. I have a little stuck on which inbound dial-peer is incorrect. I have attached my UC config. Do you mind taking a look.

Thanks

Bronze

Re: Having issues with DTMF transfer on UC520 configured with SI

yes. Ok,

It's a bit unclear to me too.

If you have a SIP phone that's connecting to the CCME part of the UC5XX, then it's possible there there's a setting somewhere in the config for this that I'm not familiar with, but by the look of your trace, you could just be sending a SIP call to the UC5XX for forwarding

Your dialled number was 915558091234

so to find out whether this theory is correct, why not create a dial-peer for testing

EG

!

dial-peer voice 915 voip

description incoming dial peer for calls sent to 915

voice-class codec 1
session protocol sipv2
incoming called-number 915.+
dtmf-relay rtp-nte

!

Re: Having issues with DTMF transfer on UC520 configured with SI

Adam,

Not sure if this is what you wanted to hear but I created that dial-peer and still was unable to transfer the call. I have attached the new log files

Bronze

Re: Having issues with DTMF transfer on UC520 configured with SI

Oh no!,

Can you please tell me what you're using to make the call.

i.e. Is this a phone that's registered on the UC560, or is it an external device ?

Adam

Community Member

Re: Having issues with DTMF transfer on UC520 configured with SI

It is an automated system which initiates the phone call using the UC5xx. Does that help?

Bronze

Re: Having issues with DTMF transfer on UC520 configured with SI

OK, When you press 1, you're expecting this to send the DTMF the the called party, like if you were calling an IVR ?

Community Member

Re: Having issues with DTMF transfer on UC520 configured with SI

That is correct. In fact the system is an IVR to transfer the call to different departments.

Cisco Employee

Re: Having issues with DTMF transfer on UC520 configured with SI

You are matching dial-peer 1003 inbound:

dial-peer voice 1003 voip
description ** Passthrough Inbound Calls from CUE **
translation-profile incoming SIP_Passthrough
b2bua
session protocol sipv2
session target ipv4:10.1.10.1
incoming called-number ABCDT
dtmf-relay sip-notify
codec g711ulaw
no vad

That dial-peer has sip-notify configured on it, but the inbound SDP from the other side for that leg is doing rtp-nte:

a=rtpmap:101 telephone-event/8000

You can either change 1003's dtmf-relay to rtp-nte, or you can add a more specific inbound peer for this call:

dial-peer voice 6000 voip

incoming called-number ABCD915558091234

  translation-profile incoming SIP_Passthrough
  b2bua
  session protocol sipv2
  dtmf-relay rtp-nte
  codec g711ulaw
  no vad

Re: Having issues with DTMF transfer on UC520 configured with SI

Steve,

Isn't the 1003 dial-peer for incoming calls? In this case the IVR is telling the UC5xx to place the outbound phone call to this particular client. So it would be difficult to set a specific dial-peer b/c the number will always be different.

Does that make sense?

If I am missing something and in fact changing that 1003 dial-peer is the solution I will do that. However, if I change that dial-peer it will not affect AA will it?

Cisco Employee

Re: Having issues with DTMF transfer on UC520 configured with SI

You can see that you are matching this peer here:

329275: *Aug 25 01:24:24.426: //-1/546501659166/CCAPI/cc_api_call_setup_ind_common:
   Interface=0x85FBBD18, Call Info(
   Calling Number=5551234567,(Calling Name=)(TON=Unknown, NPI=Unknown, Screening=Not Screened, Presentation=Allowed),
   Called Number=ABCD915558091234(TON=Unknown, NPI=Unknown),
   Calling Translated=FALSE, Subscriber Type Str=Unknown, FinalDestinationFlag=TRUE,
   Incoming Dial-peer=1003, Progress Indication=NULL(0), Calling IE Present=TRUE,
   Source Trkgrp Route Label=, Target Trkgrp Route Label=, CLID Transparent=FALSE), Call Id=47958

Anytime you make a call through a Cisco gateway, we always match both an inbound dial-peer, and an outbound dial-peer.  Regardless of whether it is an inbound, or an outbound call.  You can read on the inbound dial-peer matching algorithm here:

http://www.cisco.com/en/US/tech/tk652/tk90/technologies_tech_note09186a008010fed1.shtml

You would use either 'incoming called-number ' or 'answer-address ' to direct which inbound dial-peer you will want to match.

If you were to change peer 1003, it may mess up calls which are supposed to match 1003.  That would be any call generated by CUE.  Your alternative could be to configure CUE for rtp-nte under 'ccn subsystem sip' and then you can just do all of your inbound dial-peer matching for SIP calls with one peer configured for RTP-NTE and g711ulaw, and a statement of 'incoming called-number .'.

Community Member

Re: Having issues with DTMF transfer on UC520 configured with SI

Steven,

I created a test dial-peer (mimicing yours) in which I hard coded the incoming called number to my number and the call transfer worked. So my question back to you is.

1) If I change the dial-peer 1003 to dtmf-relay rtp-nte

     a) will that still allow that dial-peer to work as before or could it possibly cause all phone calls to fail?

     b) would a command like this voice-class sip dtmf-relay force rtp-nte work?

or

2) If I can change the setting in ccn subsystem sip to be rtp-nte do I have to apply any changes to that dial-peer 1003? Will the dtmf-relay sip-notify still cause an issue?

Thanks,

Cisco Employee

Re: Having issues with DTMF transfer on UC520 configured with SI

You will want to do both.  Make 1003 configured for rtp-nte, and go under CUE's ccn subsystem sip and also configure dtmf-relay for rtp-nte there, as well.

I expect it to not break anything, but because I don't know your completely topology and potential call flows, after making the change, test call scenarios where CUE generates an outbound call (things like voicemail phone notification, and transfers out of an AA) to make sure calls and DTMF are still working.  It may be prudent to test all types of inbound SIP calls to the device, as well, just to make sure you're matching the intended dial-peers.

Community Member

Re: Having issues with DTMF transfer on UC520 configured with SI

Steven,

That makes sense. However, why is it necessary to change the default ccn subsystem setting as well. When I created that test dial-peer everything worked just as expected.

Cisco Employee

Re: Having issues with DTMF transfer on UC520 configured with SI

Changing the CUE DTMF is so you don't break DTMF for CUE outcall scenarios, since the dial-peer that will be matched for these calls will now expect RTP-NTE.
