Hello Linux, Each xavp has a name and name values. So if you first define the name of the variable then you assign the name value it will work for you: $xavp(caller_peer=>accountname) = "Account Variable"; */*This is an example*/* $xavp(caller_peer[0]=>accountname) = "AAA"; xlog("L_WARN", "XAVP ACCOUNT NAME $xavp(caller_peer[0]=>accountname) \n"); Regards, On Mon, Nov 28, 2016 at 5:55 PM, Linux Vince &lt;linuxv(a)gmail.com <mailto:linuxv@gmail.com>> wrote: Hi, I am sure i am doing something very basic wrongly. Here is my config file snippet $xavp(caller_peer[0]=>accountname) = "AAA"; xlog("L_WARN", "XAVP ACCOUNT NAME $xavp(caller_peer[0]=>accountname) \n"); No matter what i set this XAVP at, it always prints null in log file as below WARNING: <script>: XAVP ACCOUNT NAME <null> Please help how i can set XAVP and use it further in config file. _______________________________________________ SIP Express Router (SER) and Kamailio (OpenSER) - sr-users mailing list sr-users(a)lists.sip-router.org <mailto:sr-users@lists.sip-router.org> http://lists.sip-router.org/cgi-bin/mailman/listinfo/sr-users <http://lists.sip-router.org/cgi-bin/mailman/listinfo/sr-users> -- Alberto Llamas Phone: +1-786-805-6003 TelecommunicationsEngineer Digium Certified Asterisk Professional (dCap) _______________________________________________ SIP Express Router (SER) and Kamailio (OpenSER) - sr-users mailing list sr-users(a)lists.sip-router.org http://lists.sip-router.org/cgi-bin/mailman/listinfo/sr-users
