DTMF issue on SIP Trunk

Alessandro Bertacco · ‎09-28-2013

Hi all,

I've a problem with DTMF relay only on outbound direction in this topology scenario:

SIP ISP <---SIP--->Cisco UBE ISR 2811 <--SIP---> Cisco UCM 8.6.X <---SCCP---> IP Phone

I'm using codec g711 with the provider that tell me to use in-band DTMF.

SIP trunk in CUCM 8.6 configured as standard without MTP flag, outbound and inbound calls works fine, but DTMF relay works only from SIP provider to Cisco IP Phone.

From inside, any DTMF tone are not relayed to the SIP provider.

For example, call from SCCP Phone to my mobile phone, from mobile phone I can't hear any DTMF composed to the SCCP phone, but DTMF composed from the mobil ephone are recived to the internal SCCP phone.

This happen always the same in that two scenario:

Mobile phone ------> SIP ISP ---SIP--->Cisco UBE ISR 2811 --SIP---> Cisco UCM 8.6.X ---SCCP---> IP Phone

IP Phone ---SCCP---> Cisco UCM 8.6.X ---SIP---Cisco UBE ISR 2811 ---SIP--> SIP ISP ----> Mobile Phone

Can anyone help me?

Thank you very much

Regards

Alessandro Bertacco

Hi All,

this is the CUBE configuration and debug ccsip message of an incoming call.

But how I said in the first post, the issue is the same for outgoing call.

Ayodeji Okanlawon · ‎09-29-2013

From the trace you have sent, it is clear that CUCM doesnt advertise rtp-nte in its 200 OK. That could suggest that your SCCP phone doesnt support rtp-nte. What model and firmware do you have on the sccp phone.

You should also ensure that the sip trunk on CUCM is set to use "no preference"

We might need to look at cucm traces to see the dtmf negotitation.

You can refer to this documentation to understand how to trouble shoot DTMF over sip trunks

Thank you aokanlawon,

so I've to analyze the Trace from CUCM, and also read your suggested document. Thank you so much.

I'll be back with further information about the issue.

Regards

Alessandro

Alessandro,

What is set in SIP trunk(Cube to CUCM) for DTMF singnalling method ?

Enbale DTMF singnalling method -RFC2833 and try it out.

Please rate if this will help
