[cisco-voip] Tone that caller hears when he is On CallWaiting

[Anthony Kouloglou]

Dear all,
when a user has callwaiting enabled the following is happening when 
he/she receives a call:
-the called sees in the display (7960/7940 7905) the call and hears a tone
-the caller gets a ring tone and he cannot understand if the called user 
is there or not!!

Can this change? For example, when the line of the called is busy and 
callwaiting is enabled, the caller
should here a different tone?

Thanks
Anthony
