Please review the mods I suggested for autoconfig-buttons-freepbx.sh for making it work with old/patched/forks of FreePBX.

After registering, I am unable to populate the fop2 panel with all the extensions and trunks.

The contents of my fop2.cfg file is as follows:

; By default IM chats are not logged/saved. If you uncomment
; the following parameter, all chats will be stored on the chatlog
; table inside the fop2settings.db sqlite database.
;
; save_chat_log=1

; Khomp GSM interface to send SMS messages
; If there is a card plugged, fop2 will auto discover it
; and use the first one available. If you want to change it
; to a fixed one, uncomemnt the folowing line and change the name
; to your liking
;
; khomp_gsm=Khomp/b0

; --- SAMPLE GROUPS ---
; group=queues:QUEUE/100,QUEUE/101
; group=deptA:SIP/100,SIP/101,SIP/102
; --- END SAMPLE ---

; --- SAMPLE USER LIST ---
; format: user= EXTENSION : SECRET : PERMISSIONS : GROUPS
; You can enumerate several permissions and groups separated by comma
; available permissions: 'all', 'dial', 'hangup', 'meetme', 'pickup',
; 'record', 'spy', 'transfer', 'whisper',
; 'queuemanager', 'queueagent', 'phonebook',
; 'chat', 'preferences', 'hangupself',
; 'recordself', 'voicemailadmin'
;
; user=620all:queues
; user=621dial,transfer,pickup:deptA
; user=622all
; user=623meetme,pickup
; buttonfile=buttons.cfg
; ------ END SAMPLE ------

; This line is NOT commented, it executes
; the autoconfig configuration for FreePBX
#exec autoconfig-users-freepbx.sh

Please can someone give me a hand with this...

Thanks

/usr/local/fop2/fop2_server --register

There is no need to reinstall, just enter the code and restart fop2:

service fop2 restart

Best regards,
