Multi-site questions

Hello all, we are opening a branch office out of state. We are going to have a second PBXnSIP server to service the remote office. However there will be a point to point VPN between the offices. Each office will have its own set of DIDs. I have the following questions.

 

Can I set up a trunk over the point to point VPN so I can send extension to extension calls over the VPN instead of sending them out the PSTN. This should also work for calls that come in to location 1 and the extension belongs to office 2. ( I assume this is possible)

 

Next comes to failover. If office 1 should loose its provider calls would be forwarded to office 2 and could be routed over the trunk to office 1 (assuming the point to point is still up). This would cover me in case of a provider failure.

 

I think both of these should work just fine. I will need two sets of extension 8xx for office 1 and 6xx for office 2.

 

Do I have all of my facts correct? Thank you for the assistance!

 

Tom

Just remember one thing about 8xx extensions - if the mailbox prefix is 8, then you may get into some confusion.
