Call Blocking on Certian Phones
  • Log-in to the phone you want to prevent from making long distance calls. Use a web browser and enter the IP address of the phone you wish to limit. (You can get the phone's IP address by pressing #*IP on the phone itself)
  • Username: admin Password: 0000
  • Click on "Preferences" in the nav bar on the left
  • Find the box marked "Dial Plan" -- the default dial plan for the Syspine 310 out of the box is
    [1_7][0_9][0_9]|[4_5]*[0_9][0_9][0_9]|#*47|#*6368|.>#-
  • Delete that text and replace with:
    [1_7][0_9][0_9]|[4_5]*[0_9][0_9][0_9]|#*47|#*6368|.t8>#r7t0-|911|-
  • Click Apply
  • Test that phone.
You should be able to dial all internal numbers, BUT when dialing an external number, the moment the user dials 7 numbers, the phone will dial immediately leaving no opportunity for the caller to dial long distance.

The difference between the default dial plan and mine is that in the default the ending part .>#- basically means dial any number of any length until # is pressed, then allow extra digits to be dials in order to reach extensions, use automated touch tone systems etc.

In the replacement plan, the r7 tells the phone that once 7 digits have been dialed, change the wait time before dialing to zero (t0).

Hope this helps someone. If we wanted to, we could add exceptions to these rules to allow 800 and 877 numbers to be dialed, but for us, that is totally unnecessary. Also, those in metro areas with more than one area code could limit with a dial plan those area codes that could be called using a similar method.
