Hello,
two FAX maschines are connected to FreePBX.
FAX1 one calls FAX2.
Incoming INVITE to FreePBX contains SDP Parameter among other things:
“Media Attribute (a): gpmd:97 vbd=yes”
In outgoing INVITE SDP Parameters are completely changed
and above Attribute is missing.
What has to be changed in FreePBX, that all incoming SDP Parameters are transfered to the outgoing side?
Thanks
