What is the best way to have a call ring on someone elses ext. with distinctive rining so that they will know the call is for the other ext. I have an IP office 6.0, The customer no longer has a receptionist so someone else is using the receptionist telephone and they want their ext to ring on the receptionist phone but with a different ring so that they will know it a call for them and not the main number without looking at the display. Any help will be appreicated. Thanks
