Using Call Features
UP/DOWN key press plays a short burst of the current ring tone. If one of the audio devices is selected,
the volume adjustment applies to that device. The screen shows a pictorial representation of the volume
level.
Each volume has 16 steps in nonlinear logarithmic scale. Each setting is a 16-bit multiplier in the range
41 to 32764 in Q3.12 format (or 0.01 to 7.999 or 40 to 18 dB). Each step is equal to 58/(16-1) or 3.87 dB.
Additional volume settings can be added and accessed via the phone setup screens. These volumes are:
• DTMF Echo Volume (use <DTMF Playback Level>)
• Call Progress Tone Volume (setting the ToneScript for each tone)
Managing Ring Tones
The 900 Series phone offers 10 ring tones. The characteristics of each ring tone is configurable using a
Ring Tone script. In a Ring Tone script, you can assign a name for the ring tone, and specify two
components:
• Waveform—1, 2, 3, or 4
• Cadence—1, 2, 3, or 8
You can assign a default ring tone for each extension. You can assign a ring tone for each personal
directory entry (which overrides the default ring tone). Ring tone can be selected from the user interface.
In addition, the 900 Series phone allows two user-downloadable ring tones. Therefore a total of 12 ring
tone choices are available as the default ring for an extension or assigned to individual callers in the
personal directory.
User-downloaded ring tone are labeled User 1 and User 2 in the choices for <Default Ring>. On the
phone ring tone menu, the User 1 and 2 choices are replaced by the corresponding name of the ring tone
or Not Installed if the user ring tone slots have not been used.
The user ring tone (1 or 2) can be downloaded using the phone web interface with the link:
http://phone_ip_addr/ringtone1[?<url>]
Where <url> syntax is [tftp://][host[:port]]/<path>.
Only TFTP is supported. If the host is not specified, the TFTP host is the web client. The default port is
69. To remove the User 1 ring tone from the phone, set the <path> to delete, as follows:
http://phone_ip_addr/ringtone1?/delete
The link is case sensitive.
For ring tone User 1 and User2, the cadence is fixed with the on-time equals to the duration of the ring
tone file and off-time equals to four seconds. The total ring duration is fixed at 60 seconds. The user ring
tone names displayed on the phone LCD are derived from the ring tone file header file.
There is no need to reboot the phone after downloading a ring tone. However, if the phone is already in
ring tone LCD menu while the new ring tone is downloaded, you need to exit and re-enter the ring tone
menu to see the new ring tone name on the menu.
To convert a file for use as a ringtone, obtain a .wav file less than 8 seconds in length and convert it using
the Upload Ringtone utility available from the following website:
