IP phone provisioning generator

An IP phone provisioning file in a minute: Yealink .cfg, Grandstream XML, Fanvil .cfg with the SIP account, codecs, NTP, time zone and voice VLAN. Plus the right per-MAC file name and DHCP option 66 for MikroTik, OpenWrt, Windows and Keenetic.

Codecs in order

The file is built in your browser; the password is not sent anywhere.

How auto-provisioning works

  1. The phone boots and gets an address from DHCP, with the provisioning server (HTTP, HTTPS or TFTP) in option 66.
  2. It asks for the common file first (Yealink y0000000000XX.cfg, Grandstream cfg.xml), then its own by MAC: 805ec0123456.cfg or cfg805ec0123456.xml.
  3. It applies the settings and registers to the PBX. Keep shared settings (NTP, VLAN, codecs) in the common file and the account in the per-MAC file.

If the phone ignores option 66, check that DHCP Active / DHCP options is on in its auto-provision settings and that the server serves the file without a login. The MAC is on the label underneath; the vendor of any MAC: MAC lookup.

The PBX side: SIP trunk generator, IVR builder. Registered but no audio: NAT test, VoIP diagnostics.
