I have an engin voicebox, how do I place it in the DMZ using a Snapgear modem / router?

Please note you will need to enter the * key to define the periods in the IP address ie: 10*0*0*10 = 10.0.0.10. Make sure to hang up between each part of this step. After picking up the phone, dial **** to re-enter the config menu.

Step 1: Assign the IP

Step 1: To check that you have implemented this correctly
  1. Dial ****, once you hear the voice, dial 101# followed by 0# 1  - Hang up.
  2. Dial **** once you hear the voice, dial 111#, then 192*168*0*10# 1 - Hang up.
