I'm looking at using an Avaya VPN phone for a remote employee, simply because Cisco doesn't have one. I've figured out what needs to be done in setting up the VPN tunnel between the phone and the ASA. My question is, can the Cisco CallManager control the Avaya phone, or do I have to get a border device and an Avaya CM to make it work?
In the past on an Avaya solution I setup a PIX 501 at the remote site, and did a VPN tunnel to a PIX 525 at the headend. That gave the IP phone the connectivity needed.
Kind of hard to travel with a PIX, but if it is for a "telecommuter" type employee, something like this that might work. I've heard of some issues with sccp surviving NAT though, so you might hit a roadblock there. Maybe worth looking at, but it was several years ago i did this, so who knows.
