Automatic Phone Provisioning

  • Phone provisioning is used for automatic configurations of selected hardware SIP phones.

Phone Provisioning Means:

  • phone automatically connects to the PBX after booting and is assigned to the SIP device

  • phones are automatically configured (for example directory settings, memory keys, etc.)

  • phones are managed in the administration interface

  • phone firmware can be automatically updated

How Phone Provisioning Works

  • The telephone boots in the network and sends a DHCP request for an IP address.

  • 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 TFTP (Trivial File Transfer Protocol) server address - PBX, or HTTPS URL (including authentication information)

  • SIP phone connects to TFTP/HTTPS server integrated in PBX

  • PBX server contains generated configuration file suitable for the particular phone

  • The phone is configured using the values it has acquired in the configuration file and after automatic reboot is ready to be used.

What You Need

  1. In the phones local network, you need a DHCP server supporting parameter 66 (known as tftp-server-name).

  2. Phone network must have access to the provisioning service - PBX server (TFTP/HTTPS)

  3. Only selected phones support automatic phone provisioning.

  4. Phone MAC address must be assigned to the SIP device

How to Add a Phone

  1. Manually (Manage → Devices → Provisioning → Installed devices)

  2. Phones can be imported from a CSV file
