Migration from PSTN to VoIP


How to transition from PSTN to VoIP smoothly, painlessly and before it’s too late

Replacing the company phone system can seem a frightening prospect, since telephone communication is an essential tool we use in our daily work life. As long as the old phone system continues to function, we prefer not to touch it, and it’s understandable. But whether you like it or not, it’s time to consider the change.
