Have you got any extensions defined that aren't physically connected to
I replaced an ancient Asterisk version with a bang-up-to-date 1.6 version I
built myself, and was getting similar symptoms to what you describe. It
seemed not to be freeing up channels it was trying to associate with
I made sure that every entry in sip.conf had a corresponding phone plugged in
somewhere, then went through the dialplan and removed all references to
anything that wasn't mentioned in sip.conf. (And there were a few.) It
seems to have stayed up since then .....
