The part with SIP is probably not that difficult to change. The main problem is with the media transports. At the moment media transports are precreated, shared among accounts, and they use single configuration. I suppose if we make STUN configurable on per account basis, then the same should be done on the media transports too. Which means media transports cannot be pre-created, they need to be created when there is new call. And there lies the difficulty, since media transport creation may not complete immediately, for example when waiting for STUN resolution. Which means the incoming call event needs to be delayed. Which means the event needs to be stored somewhere, and so on. It is a desirable feature, unfortunately it's also not straightforward to implement. cheers Benny > Michael. > > > -------------- next part -------------- An HTML attachment was scrubbed...
