[Freeswitch-users] Howto setup BLF event lists?

[Michael]

Hi

I am pretty new to all this, so bear with me.

I have Grandstream phones running with my freeswitch setup. I would like to 
use the BLF which works via event lists. It seems that freeswitch supports 
this.

However, I do not find any documentation how to setup such an event list. 
The only thing I know is where I need to enter the URL (whatever it may look 
like...) into the Grandstream.

Can anybody hint me to some documentation?

Thanks a lot

Michael
