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
