[asterisk-users] Asterisk => Master and Slave ?

[Noc Phibee]

Hi

a small question:

I have one Asterisk Server with:
       VoIP Provider gateway for incomming/outgoing call
       5 VoIP Phone
(i name it "Master")

i want add a another Asterisk server but only connected to:
       5 new VoIP Phone
       To the master for incoming/outgoing call (in g729)

It's possible ?

anyone have a sample of config ?

thanks
