Thank you Devin,

  So the issue is on the CUCM Trunk configuration side?

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

Alessandro Bertacco
