Yes some movement their we are looking now to an on line booking system type software package design around a medical practice, not too spendy either.I would have thought with this kind of service someone would want to confirm they can get something booked there and then, personally I would not leave a message and carry on ringing around to get one booked. I would look in to a call answering service as long as they are able to hold her booking information. If not it is just an expensive live answerphone, and the client will merely do as before and call around other businesses.
