I currently have my VFX line set up with asterisk, and today started migrating to a new server. I am using *exactly* the same config on the new server as on the old one (in fact I have copied /etc/asterisk/* verbatim), however the new server refuses to register with VFX, and simply gets stuck on '180 Request Sent'.
The VFX line has been removed from the old server's config and has been de-registered, so it can't be a conflict between the two.
Is the VFX service IP-locked to one particular asterisk server? If so, how can I get this IP changed?
