VoIP behind NAT

More and more phone lines are being switched to VoIP, especially where FTTH is being deployed. When using the ISP modem/router it usually performs the ATA (Analog Telephone Adapter) role too, and it is already configured for VoIP – just plug the telephone in one of its PHONE/TEL ports (technically – FXS ports), or connect […]

Use Ventoy to install TrueNAS when BIOS can’t boot from GPT partitions

Latest version of TrueNAS Core ISO files, after being been “burned” on a USB disk for setup, won’t boot on older motherboards with older BIOS predating UEFI.
