Summary:                    Odd Behavior when dialed sip channel doesn't exist
Description: 
I found this previous issue that seems to be similar to mine:

https://issues.asterisk.org/view.php?id=18708

but the reporter was referred to forum.  I believe the issue may be more
than a support issue.

On asterisk 1.6.1.13, the Dial command simply fails on a non-configured
extension and falls through the dialplan, terminating the call.

Using ChanIsAvail on the 1.6.1.13 system, I get an ${AVAILSTATUS} of 20,
which is expected.

On 1.8.2.3 the call stays inside the Dial command with the output below
and does not fail as expected.  The ${AVAILSTATUS} is 0 which doesn't
appear to be appropriate.

If I stay on the phone, the __sip_xmit messages will repeat until I hang
up.

It interesting to note that the bogus extension I dialed was 166 which
shows up in the output below in the IP address.

That did not resolve my issue.  Still seeing the same behavior.
