Summary:                    [patch] Autocreated peers not deleted when
unregister explicitly, become zombies
Description: 
When a SIP peer is autocreated (per `autocreatepeer=yes' in sip.conf), and
later explicitly un-registers, the peer record in Asterisk is never
deleted. 

The `sip show peer' command output indicated `Transport : UNKNOWN'. This
changes the moment the peer unregisters; before that, the transport is
indicated as UDP.

The peer stays in the list forever, but registration with the same name
becomes impossible. Each REGISTER message is rejected by Asterisk, and the
following error is printed:

[Oct  7 02:21:31] ERROR[26490]: chan_sip.c:11650 register_verify: 'UDP' is
not a valid transport for 'dyn-Q-N5'. we only use 'UNKNOWN'! ending call.
[Oct  7 02:21:31] NOTICE[26490]: chan_sip.c:19958 handle_request_register:
Registration from '<sip:dyn-Q-N5 at 192.168.0.91>' failed for '192.168.0.103'
- Device not configured to use this transport type

If, however, the peer fails to register within its registration expiration
time, the record is deleted as expected.
