When a call is madeusing a leading number allocated to a gateway group, it is routed to the lowest-numbered available devicewithin that group. In other words, if the lowest-numbered device is busy or not available, the call slides to thenext available device.[Example]PBX-1V-IPGW Private IPNetworkPBX-2IP-GW(1)IP-GW(2)PBX-3IP-GW(3)IP-GW(4)Gateway Settings List1.
