I am sending out a fax via hylafax. I have an exlatix server and and asterisk server. The Hylafax sends to the elastix server then the elstix server passes the call to my centeral asterisk server at the colocation. then the ASterisk server passes that call to the Sip provider. It seems to make the call but never sends the fax out. it it as if as soon as there is a connect, the fax system trys sending before figuring out there is even a fax on the other side and times out quickly.
