I tried it but it is sending the unregister message to the second register
user.I want to send the message to previous.
First user register: ok
Second user register: register, and kamailio will send a message unregister
to the first.
First user: get unregister Message
Sorry, maybe I'm not understanding something. Now is sending the message to
contact.
