Its an issue when you set up a IAX link between two "close by" peers. You tend to think that you don't need jitter buffer, or can set the settings down low. But if you take a call from that close-by peer that actually comes from somewhere else, and you suddenly might need a big buffer. So it would be nice if JB setting could somehow by negotiated. Anyway - a trick that comes to mind to get your packets dejittered before sending to the other box is to interpose a Local channel. So - when you handle the incoming call, on your intermediary machine, rather than Dial() the third box, rather dial a Local/ channel that then dials to 3rd machine in turn. Then, chan_iax2 will by bridged to the local/ channel, and will dejitter.
