SOLVED: SIP phones can't pick up incoming call on analog (PSTN) trunk - signalling problem?
Yo!
I changed callprogress to no, and in wcfxo.c source around line 334 i changed
the value 32000 and -32000 to 10000 and -10000 because it had something to do
with the DC voltage when it was ringing.
I found reference here (http://www.voipuser.org/forum_topic_1791.html) with an
interesting diagram of wiring that was incorrect for sending voltage to a
phone or something like that.
So put it in your asterisk knowledge bases.
Cheers, have a good weekend

Call signalling on BT FeatureLine Compact (Sangoma A200)
Hi,
I have a TrixBox install with a Sangoma A200 and 4 FXO ports, there
are 3 BT lines connected directly to these ports.
One of the lines has BT FeatureLine Compact and this is the line I am
having problems with, the other 2 lines are working perfectly,
detecting CID, answering incoming calls and placing external calls via
SIP devices.
I am receiving a error log entry:
