Hi Frank,

Section 2 of the draft mentions that signaling path of the PING method is established as a result of a call setup. Now what I understand is that main purpose the method is to keep the signaling path alive or to check the validity of the signaling path. This means that it would mostly be sent outside the context of a session. In such context I guess it has to follow path of a dialog establishing request.

Section 2.1 lists the headers that are expected in the PING method. Well, I have come across devices using Require and Proxy-Require header in PING messages.

Section 2.2 mentions the responses that are expected for a PING request. I was wondering that it is very well possible that if a server receives a PING request which is addressed to something that Server does not know about it is most likely to send a 404 response.


regards
Rayees
