Hi,

So, I enabled the full logger, and the strange thing I see is this message:
"Got T.38 Re-invite without audio. Keeping RTP active during T.38 session"

It seems that this might be the reason Asterisk initiates a reINVITE 
with voice codecs, after connecting the 2 parties.

Is there a way to disable that action, or do we need to add T.38 somehow 
to the list of codecs? I followed the instructions on the default 
sip.conf to include the line "t38pt_udptl=yes,redundancy" in the general 
section and in each of the parties.

Thanks.
