Provisioning

Phone provisioning is used for the automatic configuration of selected hardware SIP phones. Instead of configuring each phone by hand, the phone picks up its configuration from the PBX when it boots. Provisioned phones are managed under Settings β†’ Devices β†’ Provisioning.

What Phone Provisioning Means

  • The phone automatically connects to the PBX after booting and is assigned to its SIP device.
  • Phones are automatically configured (for example directory settings, memory keys, etc.).
  • Phones are managed in the administration interface.
  • Phone firmware can be updated automatically.

How Phone Provisioning Works

  1. The telephone boots in the network and sends a DHCP request for an IP address.
  2. The DHCP server accepts the request, assigns an IP address and sends it back in a DHCP reply. Besides the IP address, the message also contains the TFTP (Trivial File Transfer Protocol) server address – the PBX – or an HTTPS URL (including authentication information).
  3. The SIP phone connects to the TFTP/HTTPS server integrated in the PBX.
  4. The PBX server contains a generated configuration file suitable for the particular phone.
  5. The phone is configured using the values it has acquired in the configuration file and, after an automatic reboot, is ready to be used.

What You Need

  1. In the phone's local network, a DHCP server supporting parameter 66 (known as tftp-server-name).
  2. The phone network must have access to the provisioning service – the PBX server (TFTP/HTTPS).
  3. Only selected phones support automatic phone provisioning.
  4. The phone's MAC address must be assigned to the SIP device.

How to Add a Phone

  • Manually, in Settings β†’ Devices β†’ Provisioning β†’ Installed devices.
  • Or import phones from a CSV file.
