a network address and subnet mask.

to configure.
The IP Ranges page appears.

The Add IP Range page appears.
cIn the IP Address field, enter the IP network address that identifies the
range addresses you want to include in this ERL.
dIn the Subnet Mask field, enter the subnet mask for this IP address
range.
eClick Save.
The IP Ranges page refreshes showing the new IP address range.
7Configure the Emergency Numbers for the ERL.
Dialing an emergency number signals the gateway that the call is an
emergency and should be handled differently in case of a disconnect.
