There are various command-line SIP performance test tools (sipp?) that can do this too, I think. Also, it may be possible to modify Wireshark's plugin to periodically invoke its jitter analysis function automatically and export the results to some retrievable location. The most difficult problem would be giving it a particular data stream to home in on as a VoIP call; the easiest thing there would be to nail up your own periodic tests from a SIP UAC with definable IP endpoint locations and constantly run it with that filter. Hackjobs aside, this sort of thing is essentially what products like Brix do, as well as check in with SRTP stats. -- Alex Balashov Evariste Systems Web : http://www.evaristesys.com/ Tel : +1-678-954-0670 Direct : +1-678-954-0671 _______________________________________________ --Bandwidth and Colocation Provided by http://www.api-digital.com-- asterisk-users mailing list To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-users
