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

[Halit Sakca]

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.

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.
