[cisco-voip] Qs: G/K Technology Prefix

[mudassar khalid]

yes you are right. Gateway prefixes are just like area codes or let it
be more clear by resembling with the Default Gateway in your router.
When a route request come to gatekeeper which has no speicific
destination, Gatekeeper look upon its technology prefix and send the
request to the gateway with maching prefix.
Hope it help to visualize.
