Check out red fone.  It is designed to work with Asterisk in a HA 
configuration.  Though, if you only have one, it will become the single 
point of failure.  It's about the same price as a TE411P with echo 
cancellation.

You have two PRIs already, that can be used for fail-over.  Put a TE110P 
in each server (or TE411P if you need echo cancellation in the card or 
plan on expanding) in each server.  If one fails you have your provider 
send calls to the other PRI if one fails.
