sorry what I mean is you don't have to forward 5060 port to your PBX

Hi, No need to open 5060 port to register a trunk. For remote phones install VPN server directly on IPBX and generate certificate for each remote device (be carefull with server conf never push route if not needed) Use strong root and sip password on your PBX, never allowguest in sip conf. Use fail2ban and configure your Iptable on your PBX.

insecure=port,invite as very is deprecated since long time and why not qualify=yes

For 15 phones you'll realy save your time to make a new configuration on your VM

Thank's for your experience , it seem a cool device but SwitchPI team don't provide any compatible enclosure. I'm also playin with old phones and PBX, I have some nices models an I recently bought a second hand Draytek vigor talk 24 FXS for other use and tested this device on old pulse phones and the result is very very good, better than Grandstream with phone not rotating very well, you never miss any digits and also the configuration is very easy.

For mysql in shell use: mysqlcheck -A --auto-repair As soon your system will be ok again back it up to a new SD card as it seem your SD card is neer the end of life.

@Evgenii unfortunately in 2018 nobody whant to learn any fondamental basic :-) I agree 100% with you mate

I have eyes to read :-) first post is "When I try to format the SD card, I have write protection error" On minitool PartitionWizard select and erase all partition and it will do the job , if no your card is write protected with the switch or your card is dead, that's all. The best tool as I told before is to use dd from another linux computer and be sure all the partitions are not auto mounted on plug, simple way is to enter fdisk -l and check for the guest card partitions names, then enter umount...
