I need to add “subscribecontext=ext-local” to get the BLF lights working properly on a GXP2120. Following a post in the forums I installed the “Asterisk SIP Settings” module and added it via that and the buttons immediately lit up as expected!
Once I rebooted the FreePBX box, however, the lights stopped functioning and remained in the state they were in when they last worked. I checked the “Asterisk SIP Settings” and confirmed the setting was there. Grep’d on the server and confirmed they were still listed in sip_general_additional.conf. If I go back to “Asterisk SIP Settings” and change nothing, but submit and apply changes… they work again. So I looked into OTHER methods of setting this value and tried both sip_custom.conf and sip_general_custom.conf and none of these places have any effect at all.
What am I doing wrong or have set wrong? It works when set, but not after reboot.
