[SIPForum-discussion] What are heart beat messages in VOIP viaSIPcalls? What is the standard? Thanks

[Herve Jourdain]

Hi,



I think he meant 4028 - session timers. These can be used as heartbeat, but
the related timeout is over 90 seconds, so you need to check if that’s what
you need.

For shorter “heartbeat” T.O, I don’t think there are “standard”
mechanisms defined, but I’ve seen several implementations designing their
own.



Regards,



Herve

Thanks. But I can not find anything in RFC4208 related with heart beat
messages in VOIP via SIP calls. Could you please point out which part?
