TMS they really do know their stuff Prior to bring TMS we had a Voice over IP provider that we were not happy with, we had continuous problems with the system being down, Calls being dropped or missed all together, Voice mail not working and the list goes on. His team came in and listened to our issues, then assisted us in replacing the current vendor with a new service that has worked perfectly. His team delivered exactly what we needed, our system has increased the productivity of our employees easily by 20%. If you are looking at VoIP you need to speak to TMS they really do know their stuff.
