Folks, I’m using SIP trunks for all connections, DTMF tones work accurately for Background application and others, but it fails for VoicemailMain and Meetme (get only 1-2 digits out of 5).
I’m using RFC2833 relay on all connections. I experimented with relaxedtmf=yes, it didn’t help. The tried inband and notify on the only link whose remote peer I don’t control; notify caused 100% dtmf loss, and so did inband. RFC2833 yields frequent digit loss, but occasional successes.
I’m working with upstream provider in case their DTMF recognition is failing before they convert to RFC2833 for me. This seems odd though because it works well and consistently for other applications I frequently use.
I think there is something with VoicemailMain and Meetme that is not working well. This is on a machine with Asterisk 184.108.40.206.
Anyone seen this?
