Okay, might be a reason. but what i saw on the display was: -> Registering to Callmanager -> Registered to Asterisk PBX -> Call ended. (without hitting any button). Since i work at an ISP, i probably could setup CME on one of my boxen and you might be able to connect to it, so that we have packet traces to follow up. > That re-registration is rejected by chan_sccp, though, as > the old connection is not closed, yet.

Possible reason, looks like that, however i am surprised why the 7920 reboots instead of just looking for another callmanager. > Right now, Theo as well as Martin Bene are looking at the packet traces, > so I'm sure the issue will be located and fixed soon. i am also looking through various sources.
