Hi all,
I'm having trouble with Background DTMF detection, and would appreciate
any suggestions.
A call comes in to a Sangoma A200D PSTN line. A standard menu welcome
is used. Most of the time, callers have to wait until the message
completes in order to have their selection recognized. People end up
having to press the option number several times. Occasionally, you can
press the desired option digit during the message and it will be
selected right away while the Background message is still playing (this
is what I want all the time). Any suggestions?
Environment: Asterisk 1.2.10, zaptel-1.2.7, wanpipe-beta7-2.3.4.tgz
Machine has lots of horsepower: Pentium D 3.2 GHz, 2 GB RAM,
