Hello,
I currently use Freeswitch 1.6.8-1 in production, and have some ISDN gateways sending SDP including T.38 for voice calls (not faxes). Calls are handled without problems by freeswitch.
I have another platform, with freeswitch 1.6.19 and same configuration. However, voice calls received with SDP including t.38 are rejected with 488 INCOMPATIBLE_DESTINATION : ba17b1eb-961d-43fe-b820-cb469a8f292d 2018-04-25 23:47:39.434491 [DEBUG] switch_core_media.c:4028 sofia/internal_1/33183817938@gv-ics-prd-301 T38 REFUSE on request ba17b1eb-961d-43fe-b820-cb469a8f292d 2018-04-25 23:47:39.434491 [NOTICE] sofia.c:7566 Hangup sofia/internal_1/33183817938@gv-ics-prd-301 [CS_NEW] [INCOMPATIBLE_DESTINATION]
I didn't find any valid configuration to make those calls accepted, except configuring proxy_media, which I don't want to use.
Is this behaviour a "normal" behaviour ? Could it be a bug ? This is a very big issue for us ...
