Antwort: Re: [cisco-voip] Remotely rebooting Phone without using Callmanager (in CM not connected, but can still ping/http)

[Hans-Peter Walter]

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.
