Business VoIP That’s Cost-effective

With VoIP, you can save as much as 65 percent on your communication costs, so why stick with a traditional provider?

Unparalleled End-to-end Support

PhoneJack is your partner in growth. That’s why we’ll provide you with end-to-end support so you can always stay connected reliably and affordably.

Connect your business to the public switched telephone network (PSTN) clearly, reliably, and affordably with Voice over Internet Protocol (VoIP).

Compared to old ISDN services, VoIP is more cost-effective when it comes to call charges and rental line fees. Imagine the savings you’ll make when you finally make the switch.

With this technology, you can expand your call capacity easily without having to switch to new handsets and landline numbers (subject to your existing carrier). Plus, VoIP allows you to make crystal clear calls that are comparable (if not better) than ISDN. And if you have HD-enabled equipment, you can make calls and conduct video conferences in high definition.

Expecting disruptions or a large volume of calls? We can redirect calls to a recovery site or mobile number of your choice.
