hi
they will do as much or as little as you want, but remember the charges are based on per second billing.
you do still divert your phone to the call centre, but this is a low rate national. you can also get a package to cover these calls
so i have them get the core info name number reason for call of the phone asap. they are instructed to get rid of trouble makers and sellers asap. they estimate get rid of nuisance calls in 15 seconds, core data from a contact in 30 seconds. they then say your not available, or in a meeting etc, will call you back.
they then email this info to you. you can have it text as well but this is an extra charge, so better to use email on a smart phone.
its not for everyone you need to be busy enough to warrant the costs. its the old story you either need to time or money. if your busy on good paying work you need time, if you are slack you need money.
of course when your not busy you dont divert. when my girls are in the office they take the calls.
you can then read it at your lesuire or when convenient get back to them.
