It is likely more than you want, but I created a beginner’s guide which is stored at
I host wazo as a virtual machine virtualized with Proxmox VE, so the guide linked to above is a full instruction from bare-bones metal to working wazo as a virtual host, including instructions on installing and configuring Proxmox.
It also includes instructions on installing a CRM (SuiteCRM) and Desktop linux (Linux Mint) as Virtual machines on the same platform
If you just want wazo on bare-metal, just read the installing wazo part.
I have an updated version as a word doc if you are interested. It has updates for PJSIP and for WazoAPIs, I cannot post word docs so PM me if you want it and give me your email to which I can send it.
