[SR-Users] About xcap xuid in kamailio

[Min Wang]

HI Daniel:

    thanks a lot for the explaination.

    I have tried the jitsi and bria.

    jitsi use this kind of xcap uri:
            /xcap/resource-lists/users/sip:w102 at 192.168.51.20/index

    while bria/eyebeam use:
           
/xcap/org.openmobilealliance.pres-rules/users/w103 at 192.168.51.20/pres-rules

    The bria/eyebeam client does not have starting "sip:"  on the xuid 
part.

     so for the bria case the $var(uri) need to be updated as:

           $var(uri) = "sip:"+ $xcapuri(u=>xuid);

     Otherwise the kamailio xcap will give some ERROR: pv 
[pv_trans.c:522]: invalid uri [w103 at 192.168.51.20]

     It is the xcaps_put/del using  $var(uri) that  confuse me a little 
bit, I thought it would store $var(uri) in the db.

  xcaps_put("$var(uri)", "$hu", "$rb");
  xcaps_del("$var(uri)", "$hu");

      After checking the db, it seems the doc_uri has been stored correctly.

      It seems some magic happened in the function: 
xcaps_put("$var(uri)", "$hu", "$rb"); Just wondering why $var(uri) is 
needed if all the info are in $hu? I have not checked the source code. :(




kind regards.
