[Asterisk-Users] Asterisk Manager interface, setting global vars

[Umar Sear]

Hi all, 

Does anyone know of a way to setup global var using the manager interface. 

Basically I want to be able to have multiple manager clients login,
however in a sort of master slave scenario. So the first client that
logs in, sets a global variable which tells subsequent clients at
least one client is already logged in.

The Master would then set additional variables which the slaves would
periodically read.

Is this possible ?

Thanks in advance for any help.
