Configuring IP Phones
8 – 12 ShoreTel, Inc.
a set of custom ring tones has been identified, the system administrator must load these
ring tones onto a user's IP phone via an FTP server.
Details:
• This feature is supported on all ShoreTel IP phones, but is not supported on the
Polycom IP100 phones.
• ShoreTel offers no tools for creating or managing the custom Wave Files.
• Custom files must be loaded in .wav format. Other file formats, such as MP3, are
not supported.
• The following formats are supported by the phone:
• µ-law: 8-bit, 8 kHz, 16 kHz, Mono
• α-law: 8-bit, 8 kHz, 16 kHz, Mono
• 16-bit, 8 kHz, Mono -or- 16-bit, 16 kHz, Mono
• Only two custom tones can be loaded on a single phone. The sum total file size of
both tones must be less than 750KB. Files exceeding this size will not be
downloaded.
• If the wave file has a length less than 6 seconds, the phone will loop the ring out to
a 6-second length before it is repeated.
The process of loading ring tones onto an IP phone consists of the following steps:
Step 1 Identify Wave Files for use (via online search or by creating them
manually). These files must be stored on a server that is accessible to
the IP phone via anonymous FTP. (The server does not necessarily have
to be the same as the one that is hosting the configuration files.)
Step 2 Manually create a phone-specific configuration text file and store it in
the same directory as the standard IP phone configuration files. The
name of the phone-specific file should contain the MAC address of the
target phone where the ring tone will be loaded. The MAC address can
be found on the sticker on the back of the phone. (See "Creating the
Phone-Specific Configuration File" below for details.)

Step 3 Reboot the phone so that it will pick up the information in the text file,
along with the pointer to the Wave File. At boot time, the IP phone will
display the success or failure of downloading the phone-specific
configuration file and any configured Wave Files.
1. Alternatively, you can load the same pair of custom ring tones onto several IP phones at
the same time, but the phones must all be of the same type (i.e. all IP560g models or all
IP212k models). This approach could cause ring tone confusion if the phones were con-
centrated in one area of the building.
