[Freeswitch-users] Question on SpanDSP modem and correct usage of t38_gateway

[Dmitry Sytchev]

Hi all
We are trying to use SpanDSP modems with FS and hylafax for outbound faxing.

We dial through FS0 modem to PSTN gateway. When FS receives a reinvite to
T.38 from GW, it never replies with 200 OK, instead it begins to send t.38
data, which is ignored by gateway as it still waits for response on T.38
reinvite. After 30 seconds  timeout GW sends BYE.

Should I open ticket or we just need correct t38_gateway application params?

What is recommended setup if there is a hylafax behind Freeswitch, and
 PSTN gateway is T.38-capable and sends T.38 re-invite by itself?

I tried different combinations from wiki, results are different in details
but one thing persists - there is no 200 OK from FS to T.38 re-invite on
outbound call through FS0 modem.
