[Kamailio-Users] Help me on 'No matching subscription dialog found'

[Asterisk User]

Sorry for the trouble, but for the sake of simplicity I just removed
those subsequent NOTIFY packets from my previous mail. Kamailio does
keep on sending NOTIFY to the client but doesn't get OK.

You are right, phone is behind NAT. I just want to know if phone sends
OK to NOTIFY for the first time (SUBSCRIBE) then why not on subsequent
SUBSCRIBEs?

I appreciate your efforts, Iñaki
