[Freeswitch-users] Calls getting queued?

Mon Jan 11 15:42:58 PST 2010

Thanks. I actually got rid of all the JS callbacks and left only the main JS
script which originates 2 calls and then bridges them together. I moved all
event detection to an Event Sockets daemon. I thought I was off the hook,
but today the issue started happening again, and there was no curl involved.

Without looking at sip traces, what do you think could create a situation
like this?

I have no idea how to reproduce this issue, except wait for a few hours or
maybe even a few days, so I'm not sure recording all sip traffic would be
such a good idea. How would I go about getting traces for this?

Thanks.
