802.1Q over WAN link

[smezache]

Hi,

I have a branch office connected by a T1 line. At the main office I a voice vlan and data vlans routed by an L3 switch. I am trying to get my branch office equipments (2 2620 routes and one 2924 switch)configured so that I can have IP phone working at the branch office. The IP Schema between the main and branch office are different. What is the best way to get this going?

Thanks for the help.

With SRST enabled on the branch router, if the wan link fails, still all the IP phones will be able to call out through the PSTN. When the wan link comes back up, call flow will go over the wan
