Ive been pulling out my hair over this issue.

I have the 3cx phone system setup on a VPS with a public IP. I have a SPA-3102 setup on a dsl line behind a firewall. I went through the 3cx setup as described in online tutorials. I configured the SPA-3201 as described in the tutorial as well. I can make outgoing voice calls through the PSTN gateway but once i try to fax something the re-invite fails with 488 not acceptable here error. Below is a packet trace:

111.111.111.111 = My 3cx Public IP
sip.domain.com = My 3cx FQDN

222.222.222.222 = My DSL Public IP
dydns.homeip.net = My DSL FQDN
