I’m having issues programming a Grandstream 2200 w/ an Expansion module. I’ve created a second template (programming the other standalone 2200 went fine) and added “EXP-1” to the template with a BLF key, a label, and a value for button 1.
The phone boots and has the proper extension but the expansion module simply says “booting” with no back light. I’ve tried creating a new template a couple of times as well as deleting the config file from the tftpboot directory a couple of times.
Any ideas?
