I'm testing T.38 Fax with an SPA 2102, with Snon 2.03 latest build, Linux.
Our carrier (for inbound) supports T.38.
I've followed the instructions I can find for the SPA2102 but when I attempt T.38 the faxing fails (g711u works but with the usual reliability problems)
The T.38 Pass thourgh appears to be working since the INVITE packets in the PBXnSIP log clearly show this is passed to the UA (see below).
Do you know the settings which will work with SPA2102 T.38? If you know another ATA that has been verified to work, I'd like to know the settings for this adapter and I can possibly buy one.
