Migrate your legacy customers to VoIP this year

Posted by Daniel Noworatzky on Jan 10, 2018 3:48:00 PM

If you have customers that have not yet migrated to VoIP and are thinking about making the switch, this would be a great time to do it. According to the FCC, VoIP telephone subscriptions in the U.S. have been growing at a compound annual growth rate of 10% since 2013, and retail switch access has been declining by 11% annually during the same period. At that rate, VoIP subscribers now outnumber switched access customers, and ISDN connections are quickly sliding into obsolescence. SIP trunking is becoming the standard for PSTN connectivity.

To ensure a smooth transition, start by helping your customers answer these four basic questions to set them up for success.

Posted by TeleDynamics on Nov 8, 2017 3:42:00 PM

Almost 90% of businesses in the United States have fewer than 20 employees, according to the United States Census Bureau. To get VoIP service, companies of this size typically use a hosted VoIP service rather than having an on-premise IP PBX. With Epygi Technologies, however, the on-premise solution becomes cost-effective, even for a micro-business with a single employee. How does Epygi do it? We had a chance to ask Mario Cuello, CEO of Epygi Technologies, about what makes them unique in their ability to deliver robust, feature-rich systems at such accessible prices.
