Hidden Menus

The advanced settings menu has a few settings that you may want to look at.

Dial ***7469 (send) and filter for system find the lines:

  • system:network:fw_force_ip
  • system:network:fw_force_settings
  • system:network:fw_force_fw_type


Changing force settings to 1 will allow you to specify an IP in the force_ip line. (You change a setting by double clicking on the line)

Changing the FW type may help as well:

  • 0 - Non symmetric
  • 1 - Port restricted
  • 2 - Symmetric
  • 3 - Blocked
  • 4 - Unknown

tcpdump results

It is clear to see that the asterisk server is receiving the packets from the phone but the server is then sending them to the internal ip address of the phone as apposed to the vpn address.

No special settings are needed within the client to use over a properly setup VPN.

Please don't make changes to the ***7469 menu unless advised.
