New subject: [OpenSER-Users] how to register xlite user for testing with openser

25 Sep 2007

If the other *online* xlite user has registered to the openser server successfully, I
think the phone number that I am trying to call should be presented in the *location*
table. Am I correct?

Thanks
SW

Take a look at the "location" table. 

The save("location") writes information about the device registering to
OpenSER to this table. 

You should see entries for your xlite phones (both of them).

Note the lookup("location") line.  This, as you can probably guess,
tries to locate the device (specified by the RURI, which in telephone
terms, is the called number) in the location table.  That's why both
xlite phones should have entries in the location table.

The "Not Found" message is telling you that the lookup("location")
didn't find call callee.

Norm

  Now, I replaced the openser.cfg file with the one from
the openser source.
 This openser.cfg does not have avp configuration..
 After restarted openser and registered xlite, dialed an off-line user
 number eg. 5678 shown "Call failed: Not Found" on the xlite panel.
 Openser does not write any error/wraning message to the system's log
 file. Is this normal?
 Here is the new configuration of the openser.cfg:

 What should be a *normal* openser.cfg config file look like?

 Based on the xlog's in your config, you should be able to see which
 avp_db_load() is being called with no value.  Once you know which
 variable is blank, you can then try to determine why it's not being
 populated.

 Your config appears to be taken from one of the automatically generated
 ones from sipwise.  You should double check the documentation and make
 sure that you have followed all of the instructions.  If their
 instructions are not complete, you should let them know.

 Hope this helps,
 Norm

 Hi, here is the configuration specific to avp_db_load in the
 openser.cfg file:

 route[3]
 {
         route(1);
         xlog("L_INFO", "Load caller preferences for uuid
 '$avp(s:caller_uuid)' - M=$rm RURI=$ru F=$fu T=$tu IP=$si ID=$ci\n");
         # load caller avps
         avp_db_load("$avp(s:caller_uuid)", "*");
         avp_copy("$avp(s:cli)", "$avp(s:caller_cli)/d");
         if(is_avp_set("$avp(s:clir)/n") &&
avp_check("$avp(s:clir)",
 "eq/i:1"))
         {
                 # mark for anonymization
                 setflag(28);
         }

 }

 I never change this configuration.

 Are you issuing an avp_db_load() call with no value ?  That might
 explain the error message.  Probably be a good idea to post the config
 you are using.
