Is the UA sending the keep-alive doing the wrong thing ?
No. Sending NOTIFY's instead of empty packets is maybe a waste of bandwith but it is nothing wrong in sending any SIP request for keep alive purposes.
Is this a Snom phone by any chance? I know they use NOTIFY messages as a keep-alive, although a few others do as well. In my config, I have a section to handle just that:
From Kim's original mail you can see that it is a Sipura phone which sends the
NOTIFY's. I'm very doubtfull about Snom phones using NOTIFY's for keep alive purposes, because they send empty packet (4 bytes) for keep alive.
I've got a Snom 200 that sends a NOTIFY for keep-alive. It's running an OLD version of the Snom firmware, though, so I can maintain some for compatibility testing with some of our old business clients.
It always kind of bothered me that it would send a whole message, but whatever. I don't write the code. ;)
