Alternatively making it so it was part of bridging core would be nicer...</pre>

I suppose it isn't necessarily harmful, but it probably isn't needed for the infinite wait bridge.</pre>

If you haven't loaded func_jitterbuffer, a one-time warning message is good. This should be a debug log statement only.</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;">Tested simple two way calls with SIP with the SIP option jbenable on and off. While on the jitterbuffer is applied as expected and while off it is not applied. Note that this is different from behavior in trunk. In trunk if a SIP channel calls another SIP channel with jbenabled=yes, there generally will not be a jitterbuffer created unless jbforced is set. This is because trunk checks both channels in a two way bridge for the following condition:
if (((!c0_wants_jitter && c1_creates_jitter) || (c0_force_jb && c1_creates_jitter)) && c0_jb_enabled) {
/* jitter buffer creation flag is raised for c0 */
...
}
and since SIP has the wants_jitter flag enabled, the jitter buffer is not applied.
We are no longer reaching across the bridge to look at both channels when doing this, so the jitter buffer will be applied unconditionally on bridging. This means the jbforced option is no longer respected.</pre>
