Callwithus Company Bio

Callwithus provides broadband telephone services utilizing Voice over IP (VoIP) technology.

This enables users to make phone calls to any country using either a personal computer or a phone adapter, such as an Analog Telephone Adapter (ATA).

The service is compatible with any phone adapter or "softphone" that supports the Session Initiation Protocol (SIP).

A recommended option is X-Lite, a free SIP client offered by Xten.

Additionally, Callwithus provides a web-based phone feature allowing users to make calls directly from their web browsers.

The company does not support Skype, focusing solely on open and standard VoIP protocols.
