Hello,
Basically, you would just configure the vg224 as an h323 gateway, and have voip dial-peers on the CME pointing to the extensions on the VG224, pots dial-peers on the VG224 pointing to the specific port that the extension is on, and voip dial-peers on the VG224 pointing to the CME to facilitate outbound calling. Example
On the CME:
dial-peer voice 5000 voip
description VG224 Analog Phones
destination-pattern 500[0-9]
session target ipv4:[ip of vg224]
dtmf-relay h245-alphanumeric
On the VG224
dial-peer voice 5000 pots
destination-pattern 5000
port 2/0
dial-peer voice 5001 pots
destination-pattern 5001
port 2/1
dial-peer voice 5002 pots
destination-pattern 5002
port 2/2
etc, etc.
For outbound dialing from the analog phones:
dial-peer voice 9 voip
description Outbound Calling
destination-pattern [insert outbound calling pattern]
session target ipv4:[ip address of CME router]
dtmf-relay h245-alphanumeric
Hope that helped, if so please rate.
