You provided conflicting information. First you say “I want to allow all the IP in the network to make call”, then you say “to allow the whole network block”? Well which is it, do you want everyone to be allowed to send calls to your system, in which case leave the epad area empty, or do you want to block all calls so no one can make calls to your system, in which case put the tenor’s own IP in the allow area only, or do you only want some to make calls and others not. In this case you would add the ones you want to allow in to the allow table.
You can find all the information about the epad commands and how to add if you simply go to quintum’s web site, download the command reference guide for the AS/AX, etc. You can find it at http://www.quintum.com/support/products/2G/tenor_2G/index.shtml
