[asterisk-users] SIP Disconnects from Network - Asterisk Does not hangup

[JT]

Hmmm.... I agree that altering sip.conf with the RTP timeouts are somewhat
of a band-aid to the issue.  But in my observations there is one clear
indicator that I am shocked is not used.

When I have done this test - pulling the network cable on a device during a
call - Asterisk actually reports that the SIP device has become unreachable
within seconds of the device's removal.

Now one would think, just like a regular phone company, if one device became
unresponsive (unreachable), the call would be automatically dropped.  Like
unplugging from a POTS while on a call.

So why would Asterisk not use the following logic:
Is Device reachable?
Yes - Do nothing

No - Close all calls bridged to device

Seems that would solve the issue quickly and cleanly... perhaps with the RTP
timeout being an additional measure of safety

Is this an issue present in the latest version of Asterisk?  My hope was it
was simply an older bug, fixed at some later trunk.
