I’m trying to get fax to email working using asterisk 1.4.10 and RealTime.
The Number provider have told us that faxes will be passed on as T.38 but they do not actively support it.
The server doesn’t seem to interpret the incoming signal as T.38.
I have tried the following config combinations in my sip.conf and all give the same errors which will be shown below
; t38pt_udptl = yes ; Default false
; t38pt_rtp = yes
; t38pt_tcp = yes
t38pt_udptl = yes ; Default false
; t38pt_rtp = yes
; t38pt_tcp = yes
t38pt_udptl = yes ; Default false
t38pt_rtp = yes
t38pt_tcp = yes
t38pt_udptl = yes ; Default false
t38pt_rtp = no
t38pt_tcp = no
Console output
