Hi,
I have heard that there are two main methods to allow failover with openser - you can use heartbeat, which I believe is where a secondary machine assumes the primary machines IP upon the primary not responding to a ping. I understand the alternative is SRV records, which use DNS to failover when a machine goes down.
What is the advantages/disadvantages of each? What are people actually using in production with OpenSER?
Can anyone offer some advice on this?
TIA
Robert
The DNS SRV records allow you to build a load-balanced system, i.e. you have two (o more) servers both working. But your SIP clients have to support the DNS SRV in order to work properly.
Cosimo.

Yes, any SIP client (softphone, hardphone...)
Here you can find (a not updated) a list of clients supporting DNS srv C. http://www.voip-info.org/wiki/view/SRV+implementations
