phone receives a call for any line other than the line that is being used to dial out. When the phone exits the ringing state
(e.g. the incoming call is answered), the tone device of the phone will revert back to originally configured audio device.
Feature compatibility is dependant on the IP phone model (see the following table for compability details).
Configuring the Ring Tone via Speaker During Active Calls Feature
Use the following procedures to configure the ring tone via speaker during active calls feature.
No Service Congestion Tone
Administrators can configure the IP phones to play a congestion/fast busy tone instead of a dial tone when the phone is in
a “No Service” state. This feature allows visually impaired persons the ability to discern whether or not the phone is in serv-
ice and can be used to send/receive calls.
The configuration parameter “
no service congestion tone
” allows administrators the ability to enable this accessibility
feature. When enabled, the congestion tone will replace the conventional dial tone when the handset is off hook, a head-
set is employed, or the speakerphone is engaged. The congestion tone’s frequency/pattern is based on the respective
phone’s configured tone set. Additionally, the congestion tone is played on a per-line basis whereby only the specific lines
that are without service are affected.
