See http://www.ng-voice.com/redundancy-maxx/ 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." _______________________________________________ SIP Express Router (SER) and Kamailio (OpenSER) - sr-users mailing list sr-users@lists.sip-router.org http://lists.sip-router.org/cgi-bin/mailman/listinfo/sr-users
