[Freeswitch-users] ICE SDP Params

[Rob Moore]

Hi Brian,

 I've working today with our client to get a test instance of this issue
setup but to no avail. I have however been able to arrange some more
detailed tracing of a production instance of this issue which will provide
you a much better picture of whats going on.  I'm unable to post logs from
our production system to the user list without publishing sensitive
topology information so I've sent in a support ticket which contains the
following:

XML CDRs for a & b leg on an example call

PCAP trace of call flow for both legs.

Debug level Freeswitch logs for a leg and bleg.


Hopefully this will give you a much better picture of whats happening here.

Once we've got to the bottom of this. I'll post back here with any useful
information we find that other users might find beneficial in the future.

Thanks

Rob
