sipXphone ï¿½ The open source SIP softphone
sipXphone is a SIP softphone available for Windows (download) and Linux platforms ( sipXphone for Gentoo Linux). It is part of the sipX family of projects from SIPfoundry licensed under the L-GPL open source license. The sipXphone was formerly known as the Pingtel xpressa hard phone and instant xpressa softphone.
The sipXphone is an enterprise-grade open source SIP VoIP softphone for personal computer desktops and laptops. This voice-over-IP (VoIP) softphone delivers exceptional functionality, intuitive user interface, and audio quality to the Microsoft Windows and Linux Desktop environment.
The sipX softphone is typically used by road warriors and telecommuters who want to access an office phone when they travel. It provides users with the ability to carry their office phone and all of its features, applications, and directories on their laptop, while establishing connectivity to the Enterprise SIP server using the IPSec or SSL VPN capability already used for corporate email.
The sipXphone also offers integration between a user's phone and computer-based CRM, SFA, and other applications. The sipXphone is also appropriate for office workers who would prefer a computer-based phone that doesn't require any desk space.
Using the sipXphone it is possible for users to access speed dialing, corporate LDAP directories, call handling, call logging, dial from Microsoft Outlook or other contact managers, as well as other productivity enhancing applications. It includes a Java Virtual Machine that allows custom applications to be added very easily.
The phone is fully skinnable (sipXphone Screenshot).

They have sold their hardware line of business, for some reason, rumored to 3com, and, as such, there is very little information about using their hardphone with Asterisk. This Pingtel Hardphone page is the start of agregating that information. All who have experience with their rather nice-looking, full-featured hardphone with Asterisk, kindly improve this page.
Press Release As of 8/16/04 Pingtel sold its hardware division (xpressa SIP hardphone) to focus soley on supporting the open source sipX PBX solution and the sipXphone softphone.
