Hello

Sorry about that .We will check it at our side , If has issue will fix in the next firmware version .

Thanks for your reply.
I was trying to put some script in the following paths, but I get a Read-only file system error.
/gateway/etc/cron.d
/gateway/etc/cron.daily
Is there a way to put some script in those paths.
Regards,
Juan

You can build custom script in /etc/asterisk/gw/custom.sh . this will load when the system boot.
