[OpenSIPS-Users] HA, geographic redundancy

[Flavio Goncalves]

Miha,

Phones try the second DNS server automatically, so DNS refresh is not
usually a problem. The problem is with some PBXs that don't support
RFC3263. In this case, the client can implement automatic failover via
scripting, but you don't have control over it.

B.R.
