Summary: On call-waiting events, dropped audio on first call
then switch to second call when first call ends without 'flash'
Description:
I'm running asterisk 1.6.2 on ubuntu karmic. I was running a asterisk on
ubuntu jaunty, and converted configuration from jaunty to karmic. I have a
Wildcard TDM400P REV I (according to DAHDI_hardware) with three modules,
fxs, fxo, and fxs. All calls are between DAHDI FXS channel 1 and SIP. The
fxs channel 1 is configured in /etc/dahdi/system.conf as fxoks and uses the
mg2 echo canceler.
When a phone call is taking place (an incoming call is answered from
DAHDI/1), and a second call comes in. The callerid tone is sent, and the
person on DAHDI/1 can continue to hear the person on the other end (the SIP
call), but they cannot hear the person on the DAHDI/1 line. When the first
caller hangs up, the DAHDI/1 line is immediately switched to the new
incoming phone call without any 'flash' event taking place. The only
information related to DAHDI in the asterisk debug output is the
following:
VERBOSE[12345] chan_dahdi.c: -- CPE supports Call Waiting Caller*ID.
Sending 'FIRST LAST/9515554444'

I have the same situation - hoping that using "callwaiting=no" in the
chan_dahdi.conf will at least work around the issue. As this is my home
phone system, I can test potential patches without major disruption.
