[SIPForum-discussion] What are heart beat messages in VOIP via SIPcalls? What is the standard? T

[sreekant nair]

Hi,

Some time back read that there was a draft being prepared to have a Request message called PING to do exactly this. Not sure if the draft/rfc is released yet. Could not find it on Google. 
Maybe this cam help, but until then - I guess the preferred choice is the OPTIONS message. 

Thanks

 Hi,
 
Yes heartbeat messages in SIP commonly used as OPTIONS and we need to get back 200 OK in a period, if thre is a timeout to get 200 OK then we can assume that sip element is out of servise.
 
By the way in TCP it is periodic ARP messages.

Selamlar,
Halit Sakca

Hi,
 
    I guess heartbeat messages in generic term are used to check the connectivity between 
two elements and mostly it is send in OPTIONS. Like to check the connectivity of media server from
UAC.
