Nokia 770 tablet gains commercial VoIP softphone

Jul 14, 2006 — by LinuxDevices Staff — from the LinuxDevices Archive — 2 views

The Gizmo Project has ported its VoIP (voice-over-IP) softphone to Nokia's 770 Internet Tablet. Gizmo's free features include calls with other SIP-phone users, voicemail, and conference calls. Paid features include “call outs” to non-SIP-based phones, and a 10-digit U.S. phone number, to support incoming calls.

The Gizmo Project creates software that relies on VoIP services provided by, a VoIP startup founded by Michael Robertson, who previously founded, Linspire, and SIPphone services include a PSTN (public switched telephone network) gateway, provisioning, voicemail, and so on.

The Gizmo softphone supports Nokia's Tablet OS 2006 firmware release for the 770, which added echo concellation and other audio enhancements for VoIP ported to the 770's Linux-based OS from Nokia's proprietary phone OS.

Tablet OS 2006 already includes limited VoIP support through Google GTalk and Jabber clients; however, the Gizmo softphone appears to be the first commercial softphone with advanced features such as PSTN gateways to target the 770 specifically.


The Gizmo softphone is available now for the Nokia 770, and for Linux, Mac OS X, and Windows desktop operating systems.

“Call out” rates for the Gizmo softphone range between 1 and 5 cents for domestic and international calls. “Call in” numbers cost $12 for three months, or $35 for a year of service. A variety of area codes are available, but users may not guaranteed any specific area code availability.

A free “Area775” call in service is also available. It provides a free call in number with the 775 prefix normally associated with Northern Nevada. Additional Area775 options available for a nominal fee include number selection, fax numbers, and toll-free voicemail access.
