I've got a PBX system and 8 Cisco SPA504G Phones.
I'm trying to configure the unused line keys on the phones to be Busy Lamp Field and Registration User PBX.
This is the setup I used under the 'Phone' tab for each unused Line Key:
Extension: Disabled
Share Call App: shared
Extended Function: fnc=blf;sub=101@$PROXY;ext=101@$PROXY;nme=101
101 is obviously the extension I'm trying to monitor.
It seem not work fine.
Can 504g work fine for my request?
Regards
Alex
