Hi,<br>
<br>
I would be interested in any reports of anyone getting a T.38<br>
FAX to<br>
send or receive successfully with Zoiper. I've tried to test<br>
my T.38<br>
implementation against more than one revision of Zoiper, and I<br>
yet to<br>
see it behave sanely.<br>
<br>
<br>
I could receive yesterday from Zoiper 2.18 Windows free edition<br>
with ReceiveFAX installed with latest Asterisk 1.6.X.<br>
Would you like more details ?<br>
<br>
<br>
To be more precise, I only tried once and I wouldn't swear T.38 mode was used (I've checked) : maybe ReceiveFax would allow G711 inbound faxes.<br>
<br>
<br>

The option is t38pt_udptl = yes, and has to be set in both the global part and in the peer. The option was t38pt_udptl in 1.4 and I don't think it got changed in 1.6.<br>
Also, you can open a ticket with us (zoiper support) on <a href="mailto:support@zoiper.com" target="_blank">support@zoiper.com</a> <mailto:<a href="mailto:support@zoiper.com" target="_blank">support@zoiper.com</a>>, and if you provide us with some packet captures, we should be able to diagnose the issue</blockquote>
