<blockquote style="border-left: 1px solid #aaa; margin: 10px 0; padding: 0 10px;"><p style="white-space: pre-wrap; word-wrap: break-word;">Patch Set 12: Code-Review-1</p><p style="white-space: pre-wrap; word-wrap: break-word;">(1 comment)</p><p style="white-space: pre-wrap; word-wrap: break-word;">Is UUID absolutely required? Could you just use the unique channel id, whether auto-generated or provided in an ARI call? If so, then chan_audiosocket could easily plug into the new externalMedia thing with encapsulation "audiosocket" and transport "tcp". with no other changes to your code.</p></blockquote><p style="white-space: pre-wrap; word-wrap: break-word;">By the current protocol specification, it is a hard requirement, but I an not averse modifying that spec. UUID is nice because it is a fixed-length binary ID, but beyond that, it is completely arbitrary.</p><p style="white-space: pre-wrap; word-wrap: break-word;">I'll see what will need to be changed for this and how disruptive it might be.<br></p><p><a href="https://gerrit.asterisk.org/c/asterisk/+/11579">View Change</a></p><p>21 comments:</p><ul style="list-style: none;
