I found many mailing list threads and one wiki webpage with ideas and questions related to failover and high availability solutions. Is there any webpage or wiki page that summarizes all these ideas? What I have found: - case 1: two identical Asterisk boxes with one acting as hot-failure backup http://www.voip-info.org/tiki-index.php?page=Asterisk+failover+case1 - low tech DPDT relay http://www.voip-info.org/tiki-index.php?page=Asterisk+failover - VRRPD (KeepAlive daemon) - Linux-HA and DRBD and heartbeat monitoring - many mailing list postings with partial ideas Should I ask the asterisk docs list instead?

We are building asterisk clusters using mysql replication. All the configuration and cdr data is stored using the res_mysql module. Replication creates identical servers. Then, the phones register to each server using DNS SRV records. If any server goes down, all the phones registered to that server will register to any of the remaining servers. The only downside of this is that all active calls get dropped once the server goes down, but users can make and receive new calls instantaneously. Another idea is to use Asterisk Realtime so that the mysql replication will share registration information between servers, thus eliminating the need for the phones to re-register. Has anyone successfully implemented this or something similar? --Anish Message: 8 Date: Tue, 23 Aug 2005 08:33:03 -0700 (PDT) From: "Jeremy C.

If I use hearbeat I need a failover system for ISDN Lines, not? I waould like that if Server A crashes, Server B Control SIP Registration and ISDN Lines.

Setup correctly failover is fully automatic. 2. u can use "www.nagios.org" or similar installed on C to monitor A and B Senad _______________________________________________ Asterisk-Users mailing list Asterisk-Users@lists.digium.com http://lists.digium.com/mailman/listinfo/asterisk-users To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-users

Do you know about this?There is a new product form Redfone that will help provide a failover with the T1/PRI connections.
