[SR-Users] Event route websocket:closed and function unregister

[Володимир Іванець]

Hello all!

I have *event_route[websocket:closed]* configured. By using *$si*, *$sp*
variables and data from special hash table I can figure out information
about account that was disconnected. I'm trying to use *unregister*
function against but with no luck.

1. I'm creating variable which contains (as an example): "
sip:100-test at 127.0.0.1" string, where "100-test" is username.
2. lookup("location", "$var(user_uri)") - runs fine. I'm getting a match
and lots of useful variables including *$ruid* are being set:
*/usr/sbin/kamailio[27169]: DEBUG: registrar [lookup.c:256]:
lookup_helper(): contact for [100-test] found by address*

3. But unfortenately *unregister* with same variable does not
work. unregister("location", "$var(user_uri)"):
*DEBUG: <core> [core/parser/parse_uri.c:1282]: parse_uri(): bad uri,  state
0 parsed: <you@> (4) / <you at kamailio.org <you at kamailio.org>> (16)*
*ERROR: <core> [core/parser/parse_to.c:81]: parse_to_uri(): failed to parse
To uri*
*ERROR: registrar [save.c:1040]: unregister(): failed to extract Address Of
Record*

I was trying to manipulate *$var(user_uri)* variable's content but could
not make it work.

It's interesting that variant with *$ruid* - *unregister("location", "",
"$ruid")* will work but unfortenately it works only with *modparam("usrloc",
"db_mode", 1)*:
*ERROR: usrloc [urecord.c:655]: delete_urecord_by_ruid():
delete_urecord_by_ruid currently available only in db_mode=3*

I was wonderring if someone could tell me if I'm just using
*unregister* function
with uri parameter in wrong format or there might be some other problem.

Thanks a lot!
