Polycom Phone Boot Process
As of R10.1.0, the Netvanta 7100 added the capability to support different firmware images per phone mode. This
necessitated changes in the structure of files downloaded by Polycom phones. To accommodate the multiple firmware
images, many of the files are broken up by phone model and by firmware version. Each file listed in the table below also
contains examples of the R10.1.0 changes.
Additionally, changes were made from version 3.2.x to version 3.3.x, detailed below.
During the Polycom phone boot process, several things happen.
1. Phone boots and requests Dynamic Host Configuration Protocol (DHCP) parameters
2. NetVanta 7000 Series Product responds with these parameters:
a. IP address, subnet mask, and gateway in VLAN 1 (10.10.10.0)
b. TFTP server address (tftp://10.10.10.1)
3. The phone then attempts to download the following files (in this order) via TFTP:
Note that since TFTP is used on the initial boot, a username and password is not required for the phone to
download its file on first boot.

bootrom.ld Polycom bootrom file Required to upgrade any new or
replacement phones.
mac.cfg Tells the phone which app file, config
files, and misc. files to download from the
boot server.
By default it contains a reference to:
• sip.ld
• polycomboot.cfg
• customer-sip.cfg
• extension-mac.cfg
• adtran-sip.cfg
• sip.cfg
• This file is created on
CompactFlash
®
in the Polycom
folder when a new user account is
created.

• If not found by the phone, the phone
will download 000000000000.cfg
instead.
