I’ve been trying to add a public ip client for a remote office to our system. So far, the client cannot successfully register.
The far side client is on a static IP address, with a standard SOHO type router. The client phone behind the router is either a Cisco 7940G or Aastra 480i (tried both, neither worked).
Under “Asterisk SIP Settings” in FreePBX I’ve set:
IP Configuration: Public IP
In the system firewall, I’ve allowed tftp, port 5060, and ports 10000:20000 for the specific public IP of the client.
Unfortunately, the phone doesn’t register. There are no entries at all in the asterisk log (no rejections, failures, nothing). It’s like it’s being blocked by the firewall, though the firewall has been explicitly configured to allow the traffic. I even tried shutting down the firewall service completely, with no success.
Any suggestions as to what I’ve missed or done wrong?
