[SR-Users] Doing automatic unregister when a WEBSOCKET connection is closed.

[Peter Dunkley]

When you call unregister() without the new ruid parameter it parses the
current SIP message to get information needed to do the unregister().

There is no real SIP message associated with an event_route[] so
unregister() will not work.

The way to get this working is:
1) Use Git master so that unregister() with ruid is supported
2) Modify save() so that upon successful creation of new contact it copies
the ruid created by usrloc into the sip_msg.ruid variable for the current
SIP message.  This means that on return from save() the $ruid PV will
work.
3) Use a hash-table to store $ruid, $tU, and $td indexed on $si:$sp
4) Then when event_route[websocket:closed] is called you can retrieve the
information from the hash table and call unregister().  Use the $tU and
$td you have cached to construct the unregister() URI parameter.

Regards,

Peter
