I installed 7937 but not display the extension & external mask both on the LCD panel.
-7937 software version=1.3(4), this is latest firmware from CCO
-busy trigger=1. I found some forum suggesting to change to '2' but no luck.
My expectation is, display exension and external mask both in the LCD panel which is same way as 79x5 IP Phones.
-if I configure 5 digits extension only without external maks, display 5 digits extension on the top-right area
-if I configure 5 digits extension and 10 digits DID both, display 10 digits DID on the top-right area.
why I cannot get both (extension and external mask) on the LCD panel with 7937 IP Phone?
