NAT Settings
Field Description
Dial Plan Dial plan script for this line.
The default is (<9:>xx.)
The dial plan syntax is expanded in the SPA3102 to allow the designation of three
parameters to be used with a specific gateway:
• uid – the authentication user-id
• pwd – the authentication password
• nat – if this parameter is present, use NAT mapping
Each parameter is separated by a semi-colon (;).
Furthermore, it recognizes gw0, gw1, …, gw4 as the locally configured gateways, where
gw0 represents the local PSTN gateway in the same SPA3102 unit.
