[SR-Users] Expect the kamailio's sip account is unregistered state when the client app is shutdown

[xuefeng zhang]

Hi Daniel,

I understand your reply.The kamailio can set the "IIR" to send the OPTIONS

But I don't found out the knowledge of the "IIR".

Would you give me some things how to do it.

Thanks!
