I need a remote phone. To start out, I'll either use port knocking, or if there are issues with that, travelin man 3.
The problem is that the SIP and T1 provider, Integra, has changed the way they provide a SIP circuit. They give you an External IP address that has no actual internet connectivity--just 5060 to their sip switch and dns to their dns servers. So that IP address is what I connected to the sip switch by placing that IP address into the External IP field in freepbx SIP settings. In order to receive updates for the system, I placed a cisco router/firewall that has dual wan, bound rtp and sip ports to the wan interface that has the sip circuit, then failed all other traffic to the other wan interface which has a different external IP address from the one that I used in the external IP field for the sip header.
SO... now I need help big time because I really need a remote phone. Other than changing the sip header to a fqdn and then on the external site create a private dns server that the phone points to with a separate setting... I don't think that's going to happen. Or, of course, a site-to-site VPN... any other possibility?
