How to enable queue_log on the embedded Asterisk of a Yeastar MyPBX?

Question

I have an old PBX from Yeastar that contains an instance of Asterisk 1.6.2.6.
How can I enable the queue_log setting and have it persist across reboots?

Answer 1

First, you have to enable SSH access from the web interface (System / LAN settings / Enable SSH).
Then log into the MyPBX and create the file /persistent/custom-cfg/logger_custom.conf with the following content:

[general]
queue_log = yes
; enable log rotation and removal of the archived file to avoid filling up the partition
rotatestrategy = sequential
exec_after_rotate = rm ${filename}

Finally, reboot the PBX:
asterisk -rx 'core restart gracefully'
