[Freeswitch-users] loss of audio for 30sec in middle of call

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?

sofia global debug sla
sofia global debug presence

Or do I need to packet-trace everything, then troll through that?

Cheers,
Fraser
