Scenario 1

In this scenario there are 2 local zones (LanguedocRoussillon and MidiPyrenees) , in each zone there is one gateway.

ps: a local zone can contain more than one gateways .

h323-gateway voip h323-id Montpellier
h323-gateway voip bind srcaddr 192.168.10.51

Create a dial peer to allow routing calls to toulouse
