This would be a distinct REGISTER request, so it should not have the same CSeq or Call-ID as any other from that UAC recently.

So, provided I understood your question correctly, it's a moot point.

Hi,

When I want to unregister, I have 2 ways
1. Append ;expires=0 in Contact field
2. Add another Expires : 0 header

with CSeq, Call-ID not the same with when i register

Does Kamailio check for the saem Cseq, Call-ID to allow unregistration ?
