Do you have a spare PRI on the Avaya box? Why not just roll the spare PRI over into a local asterisk box then you can have IAX trunks out to each remote office. You will get better bandwidth performance when multiple calls are placed and you can extend the capablities of Asterisk into the Avaya box (like meetme numbers and such). This can also be a step towards moving away from the Avaya box and replace it with Asterisk if that is your intention.
BTW, Dump H.323. It is a dying protocol and is sometimes hard to make some hardware work correctly. You will be much better off with IAX for internal connections and SIP if you need to make an external connection.
Have fun....
