> 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'
