Attention Tone for Automatic Call Acceptance
If the attention tone for automatic call acceptance is switched on, the automatic call acceptance of a currently incoming call is signalled by an attention tone. If the attention tone bothers you, you can switch it off. The volume of the attention tone is dependent on the configured ringer volume.
 
Proceed as follows:
Using COMfortel Set (page settings/functions > Headset, check box Attention tone for automatic call acceptance)
Using the telephone (menu settings > headset > auto call accept > indicator tone)
