Detailed Explanations
Automatic Route Redirection
When more than one card is installed in a PBX, you can assign them to a single gateway group.
Grouping allows you to logically combine the channels of multiple cards in a PBX (there are 4
channels per card). This aids the effective use of channels in a PBX.
The following diagram and tables provide an example of this configuration.
Example of Configuration
In the diagram below, there are 2 cards (cards B and C) installed in PBX 2.
Example of Gateway Entry Programming
Through gateway entry programming, cards B and C are grouped into a single gateway group.
Example of DN2IP Entry Programming
When DN2IP entries are programmed as in the table below, calls through card A arrive at gateway
group 1, which includes cards B and C.
