The Treo is both a smartphone and a PDA (personal digital assistant). That is, apart from being a full-fledged and full-featured phone, it is also an organizer, a media center, calculator etc. It is a perfect example of a
communication convergence device.
VoIP on Treo adds more features to the machine and most importantly considerably cuts down the cost of local and international voice communication. Here are ways you can get VoIP working on your Treo.
Gizmo provides a free application to download and install on your Treo. It allows you to chat with friends on many common networks like
Gizmo, AIM, MSN, Yahoo, iChat etc. The application can be used as a softphone to call other people using the same service, for free. You will obviously need Gizmo credit to call over landline or mobile networks.
Articulation converts your Palm Treo into an IP phone. It is a service-independent tool. This means you will need an account with a
VoIP service provider, along with your Treo running at least PalmOS 5, and a wireless Internet connection like Wi-Fi, 3G, CDMA etc.
If you download and install the TalkPlus application on your Treo, you can have a second number that can make the Treo ring. Voicemailing is also possible. TalkPlus allows you to make cheap international calls.
EQO for Skype is a nice application that you can download from
www.eqo.com and install on your Treo. It allows you to benefit from the cheap SkypeOut rates while making calls. Receiving calls requires SkypeIn, but if you live in a country where incoming calls are free, you will be very happy. A GSM provider is required with this application.
A little bit like Articulation, VOYP is an application that adds VoIP capability on your Treo. It uses wireless technologies like Wi-Fi, Bbluetooth, GPRS etc. You pay for a one-time license, with no monthly fee. You will however need a SIP-based VoIP service provider. [p]Before jumping to any of the above solutions, be sure you know what model of the Treo smartphone the service or application works with, so that you are sure about your Treo's compatibility with the service or application.
