Defining Multiple Zones Example

The following example shows how to define multiple local zones for separating gateways:

zone local gk408or650 xyz.com

zone local gk415 xyz.com

zone prefix gk408or650 408.......

zone prefix gk408or650 650.......

zone prefix gk415 415.......

All the gateways used for area codes 408 or 650 can be configured so that they register with gk408or650, and all gateways used for area code 415 can be configured so that they register with gk415.

Defining One Zone for Multiple Gateways Example

The following example shows how to put all the gateways in the same zone and use the gw-prioritykeyword to determine which gateways will be used for calling different area codes:

zone local localgk xyz.com

 

 

zone prefix localgk 408

 

 

zone

prefix

localgk

415

gw-priority

10 gw1 gw2

zone

prefix

localgk

650

gw-priority

0 gw1

The commands shown accomplish the following tasks:

Domain xyz.com is assigned to gatekeeper localgk.

Prefix 408....... is assigned to gatekeeper localgk, and no gateway priorities are defined for it; therefore, all gateways that register to localgk can be used equally for calls to the 408 area code. No special gateway lists are built for the 408....... prefix; selection is made from the master list for the zone.

The prefix 415....... is added to gatekeeper localgk, and priority 10 is assigned to gateways gw1 and gw2.

Prefix 650....... is added to gatekeeper localgk, and priority 0 is assigned to gateway gw1.
