Phone Power is an American privately owned commercial voice over IP (VoIP) company, based in Winnetka, California that provides telephone service over the Internet via a broadband connection.

A privately owned company founded in 2005, Phone Power provides telecommunications service in 48 states in the U.S.

Customers of Phone Power vary from single-line residential service to corporate call centers and SIP Trunking.

In September 2009, Phone Power announced the acquisition of all residential Broadvox Direct VoIP customers.

[4] In February 2010, Acme Packet reported that Phone Power had deployed its larger Net-Net 4500 session border controllers to bypass the traditional Class 4 switching.

In August 2011, Innomedia announced a large purchase order of VoIP adapters from Phone Power.

In March 2014, Obihai Technology advised clients using Obihai analog telephone adapters with Google Voice that they should switch to rival vendors Phone Power or Anveo under the OBiTALK Approved Service Provider Program[8] as Google's removal of XMPP support would disrupt use of their ATA with that service.

The "Zippy" USB adapter was replaced with a stand-alone Softphone that can be used from any Windows or Apple computer with a microphone and speakers.
