<p>Have you tried with kamctl, which uses jsonrpc and theoretically
you can pass empty values for parameters?</p>
<p>The binrpc was designed by SER devs during 2005-2008, not sure if
there is any specs for the packet format and whether empty values
are supported or not.</p>
<p>Cheers,<br>
Daniel<br>

<div>Hello Sergey,</div>

Am I understanding you right, that you've defined a
custom global variable with an empty value in the
kamailio.cfg<br>
and then want to set a string value to it and then by
executing cfg.sets global var_name "" want to clear
that value to be blank again? <br>
