I'm running Asterisk (stable branch downloaded 2-Sep-05) on RedHat 9 and I
have a TDM22B installed (TDM400 w/ 2 FXO and 2 FXS ports).
Everything seems to work except threeway calling. I can establish a threeway
call, but it uses up BOTH FXO lines. Note that I DO have threeway calling
active with my Bell service. Here's a typical scenario:
1) Call 765-1574,
2) When they answer, press flash and call 735-1056,
3) Press Flash again and I have a three way call
4) Try calling 820-2726 on the other line and I get fast busy.
Asterisk indicates that it was "Unable to create channel of type
'ZAP'" when
I attempt the threeway call. As a result, the second call (735-1056) is
placed on the other ZAP channel so there's none left when I attempt the
third call (820-2726) on the other FXS line.
There's no problem with my Bell service as I can do three way calls on BOTH
my FXO lines when Asterisk is bypassed and my phones are connected directly
to Bell.
Any ideas? My zapata.conf and the log of the example above are provided
below FYI
Thanks
Hugh

[Asterisk-Users] Threeway calling uses up two FXO lines
This is the second time that I've seen questions about this in the past
few months. My own impression is that it's not worth the trouble. Get
yourself an account with a decent ITSP, perhaps IAX2 based, and get a
DID via IP. In this way you can have multiple simultaneous incomming
calls ( to the limit of your available bandwidth) on the same number.
You can conferece on phone using SIP phones, or use a MeetMe conference
on the server.
It's a better, more manageable solution that doesn't tie up all your
POTS lines.
