I have install the Virtual Fax module and am testing it out. Everything works fine with it as long as it goes over g711. I am trying to utilize T38 but every time the trunk tries to negotiate T38 with my server it sends back ‘488 (NOT ACCPETED HERE)‘ according to wireshark. The trunk is PJSIP and I have added the additional parameters to it
t38pt_udptl = yes
t38_udptl_ec = redundancy
t38_udptl_nat = yes
rewrite_contact = no
I have also verified that my carrier supports T38 and they do.
I’m at a loss as to how to get T38 working with Virtual Fax
I was actually trying to go that route but can’t get my trunk to register. It is a static trunk with no registration and for the life of me I can’t get it to function properly. I get ‘Rejected’ from the trunk when it is on SIP.
