Hi,
You will have to get some kind of IP connectivity between two site and then make a dial-peer on CME pointing to the IP of the Avaya Server.
Example.
dial-peer voice 1 voip
destination-pattern <avaya extension generic pattern>
session protocol sipv2
session target ipv4:<IP of the Avaya server>
dtmf-relay rtp-nte sip-notify <DTMF capabilities>
voice-class codec 1
