For a small fee you can have a generic announcement and for a higher monthly fee
you can have your own branded announcement. they have heaps of add on facilities
including an easy way to record - a great bonus if like me you find yourself
travelling at the time of some of your calls and you don’t have your recording
equipment with you -You get your own number and pin which you can use 24/7 - so you can connect any time and any place!

I like this service as you can schedule the time and you can send a note to others you want on the call which you can then synchronize into your calendar. The down sides is that the call has to be pre-booked at a pre assigned time and the announcement mentions it is a free conference which may not be the image you want to portray if you are running a fee based class.
