Well, if that case the SS7 Switch to which you are connected should be 
able to load balance the call to both of your servers. I guess you have 
two point codes for you servers? If one server goes down, the ss7 switch 
received the red alarms and
stops to route calls to it. Once the server is up again it will get new 
calls.

So, we only thing you have to worry about is to keep state information 
between the two servers consistent if people record messages or access 
databases.
