Need to upgrade CCM system! Help!

My company is looking to upgrade our CCM system infrastructure.

 

Our setup:

We have several sites at different locations which have high-speed VPN links to each other.

Currently, our CCM system is hosted at the main HQ location.  

 

Our Problem:

If the VPN link drops/dies, our phone system is unavailable.

 

Is there a way we can add infrastructure/software so that we can use a server on-site as a primary and the server at the HQ as a secondary?

We can't risk any more dropped calls since our VPN link goes into maintenance quite often.

 

Any advice would be greatly appreciated.

Do you mean sub-interface? 

How do you suggest it is done?

If not sub-interface, can you provide a link to what a SUB is?

Thank you.
