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
In the phones local network, you need a DHCP server supporting parameter 66 (known as tftp-server-name).
Phone network must have access to the provisioning service - PBX server (TFTP/HTTPS)
Only selected phones support automatic phone provisioning.
Phone MAC address must be assigned to the SIP device
