4. IP-GW(4): GW Group-2
When "123XXX" is dialed, 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).

Automatic Rerouting of VoIP Calls to Public CO Lines

When a VoIP call cannot be completed successfully, the PBX can automatically attempt to make the call using
a public CO line instead. This provides a backup method of making calls in cases when IP network transmission
cannot be completed successfully.
