Hi, All

Thanks for all your reply. I use Kamailio 3.0.2. Now I know contact header is=
: $ct

I have some problem when I want to modify the header.=20
Eg.          =20
Register: UA---->OpenSer----->SIP proxy

Contact in Register request is:
----------------------------------------------
REGISTER SIP:10.30.105.30:5060 SIP/2.0
Contact: "M1080" <sip:1080(a)10.30.102.127:5060>;+sip.instance=3D"<urn:uuid:0=
0000000-0000-1----8000-00085D215A5A>";expires=3D1800;reg-id=3D0
-----------------------------------------------

However, when SIPproxy reply the 200 OK, contact changed because it doesn't s=
upport sip.instance and reg-id:
-----------------------------------------------
SIP/2.0 200 OK
Contact: <sip:1080(a)10.30.102.127:5060>;expires=3D1800;
-----------------------------------------------

My question is when forward 200 OK to UA, how the OpenSer use the original co=
ntact to replace the contact in the 200 OK from Sip Proxy.

I read textops, but I still don't have an idea for this issue.

Your reply is appreciated!

Derrick
