Subject: [Sip] how to send user defined parameters with INVITE?

Hi,

Is there a way to send user defined parameter with INVITE or STATUS msg?
Since H323 uses Q931 as signaling control and Q931 has user info element in SETUP msg, 
H323 can send Setup Msg with user info.

How about SIP?  If SIP can do it, could you let me know how?

Thanx

Frank
