I'm having an echo related problem with Zap channels that are answered
before a dial takes place, such as for IVR menus or fax detection.
Basically, it sounds like the volume gets turned up to maximum while *
is ringing the internal extensions waiting for someone to pick up, so
when you pick up the phone to talk, you get an over-amplified echo.
The sequence is like this:
exten => s,1,Answer
exten => s,2,Wait(2)
exten =>
s,3,Dial(SIP/201&SIP/202&SIP/203&SIP/204&SIP/205&SIP/206&SIP/207)
If you let it ring for a while before picking up, you get the horrible
overdriven echo. It's like putting a really large value for rxgain,
except that the volume goes down as the echo is trained out. Has anyone
else noticed this?
