<pre style="white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">Why wouldn't you want a !caller_entertained here? Granted, I'm not sure why you'd have either OPT_MUSICBACK or OPT_RINGBACK set on a channel processing text frames, but it seems like this was added here for a purpose.</pre>

<pre style="margin-left: 1em; white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">I think the logic here is that sending text frames to a device that is occupied with audio (through either music or ringback) doesn't cause any sort of weird incompatibility since it's happening on a separate stream.</pre>

<pre style="margin: 0; padding: 0; white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">Incoming calls that do not use ulaw will generate a bunch of warning messages and possibly fail when a DAHDI channel is then called if the Dial m or r options are used.
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>

With the patch, the voice frames are not passed and the diagnostic messages are not generated.</pre>
