If two or more users share the extension (bridged and call appearance), the call waiting indication will not apply.
In CS 1000, the user can enable or disable call waiting by using the FFC (equivalent to the FAC in the Communication Manager configuration). There is no corresponding FAC, so the feature is completely controlled by class of service values.
While on a call, the user may receive a second call; an audible indication is provided. The user can toggle between the two calls using a switch hook flash, although the user cannot conference the two together.
Note:
The Call Waiting feature for CS 1000 analog stations is implemented in software on the Device Adapter; SIP endpoints are handled as multi-appearance endpoints, and therefore any analog endpoint on the Device Adapter appears to be multi-appearance to the Communication Manager. The user experience is that of an analog endpoint, though.
