Auto-provisioning

Polycom ZTP (Zero Touch Provisioning) is the equivalent of Yealink RPS:

  • Register your phone's MAC range in the ZTP portal at https://ztp.poly.com.
  • Point ZTP at your VoiceTel provisioning URL.
  • Phones contact ZTP at boot, get redirected, fetch their VoiceTel config and register.

For self-hosted provisioning, the phone boots looking for 000000000000.cfg and per-MAC <mac>.cfg files via TFTP/HTTP/HTTPS. Contact engineering for VoiceTel-specific config templates.
