I have a small number of TDM400P's in the field - all with 1 FXO and 1 FXS
port, and it seems to "just work", although once or twice it does failt to
detect a hangup or the remote end, and the voicemail records some
"oooooooooooo" at the end of the message - but my old answering machine
used to do that too!
The only issue I have is routing calls through the TDM card from the
incoming to the outgoing ports, when I have fax detection turned on, the
internal analogue phones are overly loud and seem to suffer some sort of
local echo/reverb problem.
cidsignalling=v23 ; Added for UK CLI detection
cidstart=polarity ; Added for UK CLI detection
sendcalleridafter=2 ; the hidden option given by Slav from Digium
channel => 4
;rxgain=7.0 ; Need this for incoming FAXes
immediate=no ; will take the line on the first ring
callerid=asreceived ; propagate the CID received from BT
channel => 1
