[Freeswitch-users] How to change global variable at runtime

Hi all, I would like to define a global variable in vars.xml and then change its value at runtime. This value has to be read in dialplan and in fifo.conf.xml. I tried *global_setvar* from the CLI but from the log I can see that the $${var} is expanded to the old value set in vars.xml, not to the new one. What is the real effect of global_setvar command? Have I got to somehow write vars.xml and then issue reloadxml in order the change to take effect? Thanks a lot for your support. Best regards, F. Bigliardi
