Hi, look at this scenario: UA --> SBC --> SIPproxy | | mediaproxy (openser+mediaproxy)sbc use the mediaproxy for all calls. (mediaproxy) some external mediaproxy controlled by the proxydispatcher (openser)sipproxy do the accounting for the calls. I have modified mediaproxy for sending e fake BYE message in case of timeout of media to the SIPproxy. call UA<->UA, if during conference i disconnect the ethernet cable of both UA.. i need to bill anyway the call when media timeout. this is a fake BYE generated from mediaproxy: SBC - 82.215.130.50 SIPproxy - 82.215.130.51 U 82.215.130.50:60083 -> 82.215.130.51:5060 BYE sip:396006660097@82.215.130.51 SIP/2.0.
