Appendix F. Auto Provisioning Routine
General
The LIP-6800 series terminals incorporate software routines to automatically provision the
configuration and software of the phone. The basic routine employs CDP, if enabled, to
initialize LAN settings, DHCP to gather basic network and provisioning server information,
downloads configuration and software data from the provisioning server and registers and
authenticates with the SIP server using the configuration data. The files with the confgiuration
data can be encrypted so as to protect sensitive configuration customer data.
The phone attempts contact with and downloads configuration files and checks for software
updates. For more details on the Configuration files see Appendix D. Note downloads can be
disabled separately for the configuration files and software. As a default, the phone will employ
TFTP as the download protocol. Optionally, the phone can employ HTTP/HTTPS as the
provisioning protocol. If configured for HTTP/S or, if the DHCP server returns a URL for the
assigned HTTP/S Option, default Opt. #160, the LIP Phone will use employ HTTP/HTTPS and
the URL provided to access the configuration server.
DHCP
During the initial and subsequent boot-up cycles, the phone will request various data options
from the DHCP server. The following lists the DHCP options requested.
-
DHCP Option #1 Subnet Mask
-
DHCP Option #2 Time offset in seconds of the local time zone from GMT.
-
DHCP Option #3 Default Gateway (router) IP Address
-
DHCP Option #6 DNS Server IP Address
- DHCP Option #42 SNTP Server IP Address
-
DHCP Option #50 IP address of the phone
- DHCP Option #66 TFTP Server Name
- DHCP Option #150 TFTP Server IP Address, has priority over Option 66 when set.
- DHCP Option #160 default HTTP/HTTPS URL for provisioning
TFTP Downloads
When TFTP is employed, the LIP Phone will contact the server provided from the DHCP server
using the name or IP address from DHCP Option #66 or #150 or the TFTP server in memory
when Option 66/150 is disabled or not provided by DHCP. The LIP Phone will request the
TFTP server send the Global Configuration file (“sysconf_6812d_sip.cfg” for the LIP-6812 or
“sysconf_6830d_sip.cfg” for the LIP-6830). If the file is provided as an unencrypted file,
configuration data is transferred to the phone memory. If the file is not readable, the phone will
attempt to decrypt the file using the decryption key in memory (“decrypt_key”).
Changes in the Provisioning data from Global Configuration file are transferred to the phone
memory and the download the process is repeated for the Phone Specific Configuration file.
Configuration data in the Phone Specific file will overwrite data from the Global file.
