<div>Oooh, that'd be my first one - scary!<br>
Your logic sounds extremely plausible.<br>
Suspect that ESL subscription would be the technically correct way
to do it, though.<br>
I think a logged warning for failed OPTIONS request seems more
obvious, but I may as well put in both.<br>

Is there a way to get the console to show end-user

something like this:<br>

from ip 84.92.90.149<br>
<br>
But de-registrations are very quiet.<br>
<br>
Also, is there an api command to send a "SIP

particular registered session?<br>
