Jim:
Would 1.2 be why we (and another site that I know) get an occasional TT
digit triggered during a call? Its annoying to clients. I tried
turning off fax reception on the inbound route, but that didn't do it.

DTMF on asterisk 1.2 and earlier is pretty messed up. Try 1.4, as it has a
much better DTMF engine for this sort of stuff.
If you have a clean connection, you can try using InBand, but the tone
duration is very short. In the Norstar Voicemail you may be able to increase
the DTMF sensitivity, but this also increases the risk of talk-off.

Subject: [on-asterisk] Duplicate DTMF tones
Hi all,
I have an SPA-2102 connected to a Nortel phone system. I
have an issue where I'm hearing duplicate (and sometimes
triplicate) DTMF tones on both ends. That is, duplicate from
a Nortel phone or from the caller.
Both incoming and outgoing calls are going through Unlimitel.
I've specified dtmfmode to use rfc2833 on the trunk.
Between the SPA-2102 and Asterisk, I've tried switching
dtmfmode between
rfc2833 (avt), info, and inband with no luck. Also, we're
using firmware 3.3.6 on the SPA-2102.
Any thoughts on what may be causing this?
Thanks,
Sean.
