Hi all, I'm experimenting with sofia PRACK (early dialog) support, and have a strange issue.
The system I'm using is freeswitch, which uses nua as sofia interface. Standard prack support works ok, for example: invite -> <- 183 ringing prack -> <- 200 ok(prack) but in a more complex scenario, where a remote party uses update method for transferring calls, sofia stops sending prack, and events to upstream application (for example I don't receive nua_i_state events, maybe because is not yet prack'ed). The scenario is as follows: invite -> <- 100 Trying <- 183 Session Progress prack -> <- 200 ok(prack) <- update 200 ok (update) -> <- invite (new callid, to different local number, redirected by proxy) 100 Trying -> 183 Session Progress -> (newcallid) <- 183 Session Progress (newcallid) ... prack is expected here... only log that I see on sofia debug is : nta: 183 Session Progress is reliably received with RSeq: 512718638 nta: 183 Session Progress with initial RSeq: 512718638 outside dialog and then the message is destroyed in nta.c outgoing_recv() any hint on where to look ? maybe if guided into the stack I can provide some patch :) thanks, matteo ------------------------------------------------------------------------------ WhatsUp Gold - Download Free Network Management Software The most intuitive, comprehensive, and cost-effective network management toolset available today.
