[asterisk-users] Random DTMF tones generated from speech in conversations

[hbk]

Hi,

My Asterisk systems runs like a dream with mISDN, SIP and even and old
Digium board. But have almost in every conversation some irritating DTMF
being generated. The seems to be just as often from all trunks but are
worse if noise load speaker in other end.

Any good advices?

Where to look for forgotten DTMF detection settings?

Thank you!
