asterisk users - Jul 2006 - T.38 call with t38 in original SDP fails

Hi All,

I am trying to use some ATAs which support T.38 in the initial invite.

Asterisk(trunk) presently rejects the call as no audio is offered in the
initial SDP.

With ATAs behind NAT the usual method of switching to t38 seems to fail.

This method may resolve the issue of a re-invite to an ATA behind a NAT.

Any ideas would be welcome.

Hi All,

Has anybody got any thoughts here?

Cheers
