I am evaluating your phone system for a solution to some fax issues I have. I do have an evaluation license. 1) I have a Grandstream 4104 connected to the server. When I send an inbound fax, it appears to work and sends it as an email to the email address. When I look in the debug log, I do not see where the fax was received using T.38. Is there any way to confirm that the T.38 is working? 2) I connected a Grandstream 4004 to the server, and connected a fax machine to it. I set up the inbound routing so that the inbound call hits the 4104, goes to the server, and then transfers the call to the 4004. When I sent an inbound fax, it worked, however, did it use T.38 or just PCM audio for the fax? If it did not use T.38, do you plan to support this setup? 3) Same question as 2, but reverese where I send an outbound fax call from the fax machine on the 4004 out through the analog line attached to the 4104. Thank you for your response.
