VPN setup to support Avaya VOIP

[Ted_Masson]

Hello!

I'm working to deploy a few Avaya VOIP phones to be connected at employees home networks.  The phones should establish a VPN back to my edge firewall, a 4800 running R80.10.  I've struggled locating documentation that fits.  I found an SK for site-to-site with third party and some Avaya documentation that uses R75, but neither seem to fit this situation.  

 My environment already has many remote sites that use CP site-to-site tunnels amd we have SSL Network Extender deployed.  We do not have mobile access blade enabled. 

Could someone point me to an appropriate SK or provide other guidance?  

Thanks.

to be honoust, I would invest in some 1430's and manage those from the same management you manage you 4800 from and you can get those users and phones in a separate VLAN on their home network and run Site To Site VPN's from those units to the 4800, works like a charm.
