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

[Donald Lee]

Hi,

I think OPTIONS is more heavier to stand for heart beat. The response should
contain its capability and it maybe a big message.

And for the session timer, it's only exist during the session. If there was
no session, there would be no timer.

I have seen a ietf draft which was proposed by Nortel that using a new
method called PING, but I think if we use the current INFO message would be
better.

Just some idea, Please give me your thought.
