Just a side note.... Unless you have reset the max call duration it will
terminate calls after 12 hours.  The only reason I know this is that the
call hung up on the TAC engineer after 12 hours on the phone.  Not 11
hours 59 minutes but exactly 12 hours.  (note it was a 22 hour TAC case
so it only did it once)  Enough time has went by that I can :-) now.

hi all, 
finally I gave up. 

- reboot-bug: 
we are running 7.2(3.0), but we tried everything, from small packets 
to big packets, different tcp options, reset, syn, ack 
spoofed packets from gateway to phone, from that phone to itself etc. 
==> no chance,  the only thing we killed was the ospf process on the
router because of heavy load ;-). 

- just ask somebody 
in europe it was friday evening at about 10 o'clock when I began, so
nobody was/is there, no maid, 
just nobody. 

- http://<phone ip>/CGI/Screenshot 
didn't work either, as I do not have the username/pw for that phone.
Tried things like cisco/cisco, hoping 
the phone reacts, but nothing... 

- on the streaming-page of the phone I can see a stream from the phone
to the gateway, still sending 
packets (counters increase), but no reply from the gateway (counters
doesn't increase). 

So I believe the phone still think it's an active call, but shouldn't it
be disconnected when the Ethernet 
goes down?? 

I opened this thread as the guy complained about the SRST not working
properly will come 
to the office on monday morning and see an active call since friday ;-)
(i know it's not really active, but.....). 
Thats why I wanted to know how to reboot that phone. Probably it's just
pressing the speaker-button to end the 
call, and the phone will reconnect ;-). 

thanks all for your time....

I'd be interested to see what's on the phone screen.  Try to get a
screenshot via:

http://<phone ip>/CGI/Screenshot

You'll be prompted for credentials for a DC directory user who is
associated with your phone's MAC.  Of course, if your phone can not
communicate with the authentication URL this won't work.

Or as Mike said, you could just ask the Maid what's on the phone screen.
