We have Shoretel running across 2x sites at present. Head Office and a remote site (with no dhcp servers).
I have a third site that replicates the same setup as head office, apart from there not being any shoretel switches, director etc at this site.
Is it possible to use dhcp scope, helper etc to get a local voice vlan ip and point the phone using the 156 dhcp option to point back across the vpn to head office?
The switch knows about the 2x vlans and gateway will be the switch. I can route between the 2x vlans. will just need to tweak the firewall(s)..
