Hi,
I am looking for any draft of RFC that defines how to basically
heartbeat a sip device to know if it is active. Basically in a fault tolerent
enviroment
I don't want to send a request to a non responsive device. Presumably I
would have knowlege of a backup.
I have implemented a version of sending periodic OPTIONS requests to my
devices as a form of heartbeat but it could take up to the invite timeout to
know if they are alive. That can be a long time.
Is there any universal method for handling this? Is there any RFCs or
Drafts for SIP in a fault tolerent enviroment?
Thanks
Andy
