4.3.2.1 Gateway Groups

Description
It is possible to automatically reroute outgoing VoIP calls according to preassigned gateway groups.
A gateway device can be assigned a gateway group number based on its IP Address. When a call is made
using a leading number allocated to a gateway group, it is routed to the lowest-numbered available device
within that group. In other words, if the lowest-numbered device is busy or not available, the call slides to the
next available device.
[Example]
Gateway Settings List
1. V-IPGW(1): GW Group-1
2. V-IPGW(2): GW Group-1
3. V-IPGW(3): GW Group-2
4. V-IPGW(4): GW Group-2
When "123XXX" is dialled, the call is routed to GW Group-1. However the lowest-numbered device
(V-IPGW(1)) is busy or not available, so the call is rerouted to V-IPGW(2).
