We've got 10 callers using our FS server (outbound call-center), and they're reporting that during some calls they lose audio for a while (it varies, but they've said half a minute is typical). It's calling from softphone -> FS -> gateway It's intermittent though - happens to all the users, but only some calls, and it happens frequently for a while, then goes away for a while. I can't think where to start looking to find the problem - still trying to arrange for them to keep a record of affected calls so I can look in the logs, but I have looked at a couple of examples already with no obvious problems there. (Besides, the logs are generally quiet during the call anyway.) Any suggestions of where to look or what else to try? In the wiki it talks about some new sofia debug commands, but doesn't explain them at all - anyone know if they'd help? http://wiki.freeswitch.org/wiki/Sofia#Debugging_Sofia-SIP sofia global debug sla sofia global debug presence Or do I need to packet-trace everything, then troll through that? Cheers, Fraser
The only thing that would be relevant is pcaps. there is a tool that will put all of your calls into individual pcaps http://wiki.freeswitch.org/wiki/Packet_Capture#pcapsipdump Most likely its downed route or router rebooting you could also try pinging or mtr the box from one of the host sites and look for loss.
