[OpenSIPS-Users] Cluster call restore during conference call

[Răzvan Crainea]

Well, that depends - you can use dispatcher, or something similar that 
detects if the service is responsive by pinging it periodically, and get 
an event when it is not responding. However, after detecting this, I am 
not sure what you can do from FreeSWITCH's side, because I don't know if 
they have some sort of conference persistency or not. OpenSIPS cannot 
send re-INVITE's, because he doesn't know where/to which FreeSWITCH 
instance.

Best regards,
Răzvan
