asterisk users - Sep 2005 - Stupid tricks: preventable?

I just experienced something I'd rather not experience again.

Using a SPA-841 SIP phone connected to our Asterisk server, someone
dialed their own extension, answered, and then transferred the call
using the phone's "XFER" soft key. This does a SIP REFER.

Now, the phone has dropped out of the loop, and Asterisk has connected
the two call legs into a loop, as far as I can tell.

I tried a "soft hangup" on each of the channels, but nothing happened.

Is there any way to recover from this, short of an asterisk restart?

Thanks,

i think you need a restart, then:

[your-local-extension-context]

exten =>
_XXXX,1,Gotoif(["${CALLERIDNUM}"="${EXTEN}"]?2:4)
exten => _XXXX,2,Playback(you-are-a-frigging-idiot-stop-that)
exten => _XXXX,3,System(/etc/asterisk/email-administrator-moronic-behavior
${CALLERIDNUM})
exten => _XXXX,4,InsertNormalDialingBehaviorHere

I can't think of a reason why someone would want to dial their own extension
from their own extension, let alone transfer it, unless they want to leave
themselves voicemail??

Was this guy just trying to be a smart-alek?

Heh, good solution.

Something like that, I think.

That's good, the first reason I've heard of to call yourself at all.
In this case, on priority 2 above, I'd probably just send them to
Voicemail.

Though the whole "agent login" issue complicates the test
somewhat as well.

Thanks,
