No, there are no lock-in contracts with PBX Blue.
Yes, we can setup a free trial for 14 days, so you can evaluate the service and all its functionality.
This can vary from one week through to a month or longer. A lot of this will depend upon the losing carrier (some of them can be very difficult to deal with) and also whether you need a simple (CAT A) or complex (CAT C) port. During the porting phase we can present the correct caller ID on outbound calls, even before the porting is complete so there is no interruption to your business.
