I just want to ask if this is possible. What we are using right now is Avaya and we want to eliminate or lessen the tie-trunks between sites. Is it possible to connect the Avaya switch to a Cisco router then Cisco will convert the voice traffic into IP, route it in the IP cloud then pass it to another Cisco router that will pass it again to Avaya switch?
So the phones are registered in Avaya then the one that will route the voice traffic is the Cisco switch.
Is this possible? Thanks.
