[Asterisk-Users] SIP Date: header

[John Todd]

So, a quick look through a full session of a call between two SIP 
phones doesn't show that there is a Date: header being inserted 
anywhere in the SIP headers.  I _swear_ I saw that earlier, and in 
fact, I recall watching Mark fix some syntax this spring on the floor 
of the VON show to make the SNOM phones work correctly for call 
timestamps.  I even found the Date: header code block in chan_sip, 
but no evidence of it in a packet dump with CVS from this morning.

Is it only inserted under special circumstances, or is it on any transmission?
