[cisco-voip] R: R: DTMF outbound Issue un CUBE

[Buchanan, James]

Hello,

As I see it you are missing the default voip dial-peer that controls your communication from the CUBE to the IP phone, even in an outbound situation. That dial peer would look something like this:

dial-peer voice 9999 voip
description Default VoIP Dial-peer
incoming called-number .
progress_ind setup enable 3
modem passthrough nse codec g711ulaw
voice-class codec 1
 voice-class h323 1
dtmf-relay rtp-nte
fax-relay ecm disable
fax rate disable
ip qos dscp cs3 signaling
no vad

Remember that each outbound VOIP call has two legs—the leg from the CUCM to the CUBE and the leg from the CUBE to the PSTN. You need a dial peer that will control the traffic from the CUCM to the CUBE. Adding that may resolve your DTMF issue.

Thanks,

James

Hi John,
  thank you for the answer.
Yes, I mean RFC-2833/rtp-nte.

At the moment I don't have the debug, but on Monday I'll capture ccsip mess from the cube and I'll post it.
Thank you.

Regards
Alessandro

Hey Alessandro,

What do mean by in band?

Inband RFC-2833/rtp-nte

Or

Inband PCM Audio (Raw tones in the G711 stream)

Do you have a debug ccsip mess from the CUBE?

Regards,
Divin

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 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
