In Kamailio config I use empty global string variable local.trace_troubleshooting_net = "" descr "trace all SIP messages from given network"
When I check variable value I get blank string kamcmd cfg.get local trace_troubleshooting_net
I can set new value [root@host]# kamcmd cfg.sets local trace_troubleshooting_net "2600::/48" [root@host]# kamcmd cfg.get local trace_troubleshooting_net 2600::/48
Now I want to set the empty custom global variable using a command kamcmd cfg.sets group trace_troubleshooting_net "" But get error error: 400 - error at parameter 2: expected string type but record doesn't match type
How to properly set empty values?
Hello Sergey,
Am I understanding you right, that you've defined a custom global variable with an empty value in the kamailio.cfg 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?

yes, Arsen, you are correct.

Then I don’t think it is possible as kamcmd uses kamailio binrpc protocol which in turn accepts string or int as an arguments and string should be 0 terminated.
I’ve tried to reproduce your use case and execute kamcmd “cfg.reset group” - it should set the value to the default.. but it crushes my 5.5.0

Have you tried with kamctl, which uses jsonrpc and theoretically you can pass empty values for parameters?
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.
Cheers, Daniel
