This is a free trial, lasting 30 days. It is identical to the full featured service and is not a cut down 'demo".
The value of this service grows over time. As the same callers make return calls, the system fills in their past information. You can refer to past call records while they are on the line.
This is a huge win over retrieving slips of paper.
So, take advantage of the full 30 days free and involve all your staff.
Just sending yourself a synthetic message to "test" the system is not exercising how this system makes your entire operation more efficient.
