See

for example.

Your specific concern:
"Both our deployed SEMS (thanks to the Frafos Team) and our deployed RTPEngine 
(thanks to Carlos) use a Redis-Database for storing information on the current 
calls, however in both cases through a proprietary extension. The Redis-
database is distributed among the two servers, so if we start the services on 
the passive node, all sessions can continue without service interuption."
