2x similar sites configured.
Site A (HQ) using a Cisco ASA 5505 firewall and an HP Switch as the GW for all clients. 2x vLans 01 (data) and 20 (voice).
Shoretel Director, E1k, Sg90 and sg90bri here on vlan20 172.16.0.0/24
Site B (remote office) no DC's with Cisco ASA 5505 and HP Switch (with vlan 1 and 20 again).
shoretel sg90 here.
Calls between LANs over VPN are fine.
Our remote users (pickup a 10.255.255.0 IP) who connect into the firewall are having issues getting voice to work between them and users at Site B.
