I'm trying to setup an Avaya 9611g to connect to my network via our VPN. It keeps failing at exchanging keys with IKE Phase 1 no response. I've tried all sorts of different settings on the phone but nothing seems to be working. Our firewall is a Cisco ASA 5510 with Xauth enabled. I'm not sure what I'm missing to get this phone to login to our VPN. Does anyone have an idea as to what else I can try?
