[asterisk-users] Problem with the dial command

[Mike]

Thanks Jared. It answers most of my question.  Now, when the device doesn't
register, the behavior is as expected.  But eventually, any device that
registers successfully might be unplugged, leaving Asterisk to wonder where
the device has gone.

So, what's the best approach to this?  Should I put a timeout=x minutes for
that SIP registration, and force the Polycom phone to reregister every y
minutes (y being smaller than x)? How do I do this?

Is this anyway to force Asterisk to consider the peer disconnected if
Asterisk doesn't get a reply back within a second of trying a Dial command?

Is this any other obvious option that escapes me? 

Mike

This happens when Asterisk don't know where to find the peer (which is often
the case if the device has failed to register to Asterisk, for example).

This would happen, for example, if the phone registers with Asterisk but
then gets unplugged from the network.  Asterisk has an IP address for the
peer and is trying to call it, but the peer isn't responding.
