we route external calls towards a SIP Trunk (with MTP Required, RFC2833 for dtmf, and G711ALAW) using a software MTP through a dspfarm on a Cisco 2951( IOS 15.0(1r)M12 )
. External Calls, transfers, MOH, fax, ringbacks work as expected, and DTMF inbound works (we got an IVR on customer premise and it is fully functional) but we are unable to use DTMF for outbound calls at all... I've checked all configurations (regions, locations, dspfarm and media resource on phones and trunk) and everything seems ok. Any help/suggestions would be very appreciated, thanks in advance
