The else that encloses this switch statement only happens if the frame read is NOT an AST_FRAME_CONTROL. You need to move the special "caller_entertained" exceptions for VIDUPDATE, SRCUPDATE, and SRCCHANGE up into the if block above this else. Currently VIDUPDATE and SRCUPDATE are passed along without checking any flags and SRCCHANGE is not handled at all.</pre>

You get:
[Mar 6 20:39:05] WARNING[2994]: chan_dahdi.c:9061 dahdi_write: Cannot handle frames in g722 format
[Mar 6 20:39:05] WARNING[2994]: app_dial.c:1410 wait_for_answer: Unable to forward voice or dtmf
A bandaid patch was applied to silence the above warnings for each frame by setting up a translation path for future frames. The bandaid patch also emits this warning:
Codec mismatch on channel %s setting write format to %s from %s native formats %s
This problem also occurs if the dial is forked to multiple destinations: Dial(DAHDI/1&DAHDI/2)</pre>
