Re: [sipx-users] ITSP call goes through but no audio


Title: RE: [sipx-users] ITSP call goes through but no audio

The ITSP told me it was disabled. For S&G's he enabled it for one test call and then disabled it afterward--it had no effect. This happened before I forcing G.729 on the phone though. It'll be Monday before I can test with him again. What do you suggest the next test should be?

Thanks,
Matt

There is no rule that says codecs must be the same in both directions.

I doubt this is your problem - it is much more likely a NAT traversal
issue.  Is Covista Communications doing any NAT compensation on their
end - if so, see if you can turn it _off_ so that only one end is
compensating for the NAT.
