Hi Folks,
I noticed that I can't connect to external conferences which require to put a number and a passcode via DTMF.
Phones(all, SIP,SCCP) ==> cucm (SIP Trunk)==> 2921(BRI) ==> PSTN ==> Conference Bridge
The codec is set to alaw at all.
Internally all DTMF works fine, also incomming calls from PSTN works fine.
Only outbound DTMF tones will not transferred over the BRI Interface.
I checked the configuration on CUCM (no MTPs required at all)
and the Gateway (dtmf-relay) is configured for rfc 2833. From my point of view it looks good.
The trace shows me that the events reached the gateway, but the gateway doesn't send this over the BRI Interfaces.
Have anyone seen such behavior or have some advices?
Thanks
