Default setting: When in a call, another call coming in is announced visually in the status line and acoustically by a double beep.
Call waiting is set independently for each identity. If you use the phone to change the setting, it will apply to the current outgoing identity only; if you want it to apply to any other identities on the phone, you must select each one in turn as the outgoing identity and repeat the setting for each one.
The setting is applied to the outgoing identity at the time it is saved. If you want to change the setting for other identities, select each one as the outgoing identity in turn and repeat the steps.
