<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;">The code for checking T.38 in sip_write accidentally drops one frame in situations where an audio frame forces early media . If you compare with the video code below this part of the code, the frame is not dropped even though we add an 183 message. It's not a big issue, but nevertheless, frames are frames and should be treated with love and care.
Moved the T.38 check out of the lock - maybe that's wrong?</pre>
