CM DTMF not working on direct SIP to CMM 7.x

[hawles]

Hi all,

I have a CMM on the latest 7.0 and the CM is latest 7.1 as of 11/21/17. They have direct SIP integration. Internal and external calls to the CMM get through and you can hear it say welcome to Audix. Please enter your mailbox and press #. Digit tones (DTMF signalling) are not heard by the CMM. I followed the Implementation doc here: https://downloads.avaya.com/css/P8/documents/101014318. Issue happens whether you are on IP or analog phone. All other integration seems to be working. WMI lamps work. The CMM and CM are on s8300e AVP with 3 g450s for DSP/VOIP resources. The MGs are on latest firmware 38.20.1. What am I missing?

YOu may need to check below parameters between SIP signalling group on CM and switch link Administration on CMM

DTMF over IP
•
rtp-payload
if
SIP INFO for DTMF
field is set to
Ignore
on the Switch Link Admin form.
•
out-of-band
if
SIP INFO for DTMF
field is set to
Accept
on the Switch Link Admin form.

Thank You! I will compare settings of the signalling group.
And i found manual "Configuration Note 88104 – Version K (12/22/16)
Avaya S8xx0 Aura Messaging SIP Integration directly to Avaya CM", want to try it.
Signalling group and trunk is up. I hear message "Welcome to Audix" but i can't leave voice message to mailbox. There is always message "Welcome to Audix".

Does DTMF work from Phone to any other device ?

[filip36]

Sure. With calls between phones and ip phones there is no problems, only with CMM.

The problem was solved. The reason was in the table "public-unknown-numbering". I have added string for my local stations and trunk to CMM and it's ok.
