John Campbell commented on ASTERISK-23810:
------------------------------------------

I'll see what I can do, but as I am sure you understand, this is a live system and I don't really want to go and deliberatly crash it.

However, I think I know what caused it.  I have an WPU-7800 Wifi cordless phone that was still programmed to an extension.  It was on my desk switched off as it was marked as faulty.  THere was another WPU-7800 phone switched on and registered (it's replacement).  I switched on the phone on my desk knowing that it had the profile for the already active phone and I thought I got to the factory reset section before it connected to the wireless.

A spooky coincidence is that a call came through the system for that number and I think this is there the problem was.  The call successfully routed to the correct phone a second after Asterisk self recovered by this time I had the one on my desk factory reset.
