This service enables a user to answer a call while already engaged in another call. By default, it is turned on. When an incoming call is received while a user is already engaged in a call, the user is informed of the new call via a call waiting tone. To answer the waiting call, the user presses the Answer Button. (If your device does not have Answer, use flash hook, which connects the user with the waiting party and holds the original party. Subsequent use of the flash hook allows the user to toggle between the two parties.)
If the user hangs up while another party in the session is held or waiting, the user is re-rung. Upon answer, the user is reconnected to the held party. The service ends when any party hangs up.
Users can also execute call waiting via any of the Call Control Clients. When a second call is presented to the user in the Client window, the user can click the Answer button while the new party is highlighted, to hold the other party and establish a connection with the incoming call. This procedure can be repeated as many times as necessary to toggle between the two parties. The use of the telephone, and the Client can be used interchangeably during the same session. The Call Waiting service may optionally be configured to provide callers with a distinctive ring back tone when the called party is already busy on a call. Call Waiting is modified to provide a call waiting tone to In-Call Service Activation users, if they have a TDM Overlay device. Incoming calls can therefore be answered by entering the flash digits. It is then possible to toggle between calls in the same manner.
This service can be enabled or disabled either through the web portal or by dialing a configurable Feature Access Code. The use of a distinctive ring back tone informing users when a called party is already busy on a call may be configured by the system administrator through the web portal or the CLI. The default state for Call Waiting is “On”.
Cancel Call Waiting Persistent – This feature allows users to disable call waiting persistently. #43 Call Waiting Persistent Deactivation. This feature allows users to disable call waiting. When Cancel Call Waiting Persistent is active, any incoming call received while the user is already busy on a call receives busy processing. It is however possible for the user to have more than one call active if the user has originated them.
Dial Feature Access Code #43.
Cancel Call Waiting Per Call. This feature allows the users to disable Call Waiting for the next or current call. To cancel Call Waiting Per Call, the user dials *70. The system plays a confirmation announcement and then applies a dial tone. The user then dials the destination number. For the duration of the call, the user is not presented with any waiting calls. Call Waiting is automatically re-activated when the call ends.
Feature access codes can also be used from the CommPilot Call Manager. For example, the user can enter *70XXXXXXXXXX to cancel call waiting, with XXXXXXXXXX being the destination number. The system does not play a confirmation announcement. In addition, the user can just enter *70 through the CommPilot Call Manager. Then, the user’s device rings, and when answered, the system prompts for the destination number (as described above).
For telephones with hook flash available, the user can also cancel Call Waiting for calls in progress. The user can flash the switch hook while a call is in progress, and then dial *70 after the dial tone is applied. The system then responds with a confirmation announcement, followed by a dial tone. The user can then flash back to the other call, and no other waiting calls are presented for the duration of the current call.
Cancel Call Waiting Per Call has no web portal configuration parameters and is available to all users with Call Waiting capabilities.
