Thank you Anthony.

Is there anything similar to "defined" condition in dialplan? I want to examine if a global variable exists or not.

Right now, it always gives me an error if the variable doesn't exist. 

Is there anyway that I can add a condition in my dialplan to check if a global variable actually exists or not?

Regards,

Ali Pey

All global variables are always accessible from your channel so you just look for it like any channel variable.  If you set a var with the same name on the channel, it will mask the global.

 

You can also use ${global_getvar <varname} but really there is little point when you can use ${<varname>} as usual.

Perhaps you want limit, hash, or DB. Those are accessible by name from everywhere.

Although, I think there are globals too somewhere.
