<pre style="white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">This now introduces more of a bottle neck on outgoing requests and I think using the URI isn't safe (since it's possible an implementation may use the same contact across multiple instances, even though it probably shouldn't).
Doesn't pjsip have a mechanism to do resolution to active transports based on the URI already? Is it possible to leverage that and add a parameter to the URI to make it unique?
Regardless to make this more lightweight you could examine the transport on the URI and see if it is for websocket, if not then don't even do a lookup.</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;">Finding a transport requires DNS resolution. We can't let it try to do that, because of the .invalid TLD that gets used.
I'm not finishing this thought right now, since reviewboard currently hates me.</pre>
