Startup Ribbit is preparing to launch in impressive looking internet telephony service in a few months. The company's Amphibian phone service provides a ton of features, but in a nutshell you could describe Amphibian as a cross between Google's GrandCentral and Skype with a few extra bits thrown in like an open developer platform and some social networking features.

Here's how it works. You can make calls from Ribbit.com or any website with an embedded Amphibian phone application. You will also be able to load up an Adobe AIR version of the software so you can make calls without firing up your web browser. You can see a list of received calls on the web, and you can see user profiles for missed or incoming calls if they're available.

But you can also link Amphibian to your other phone numbers of VoIP accounts. So if someone calls your home, work, or cellphone number or your Skype, MSN Messenger, or Google Talk account you can take the call using Amphibian.

Ribbit has also partnered with SimulScribe, a service that transcribes voicemail into text. This allows you to read or even search your voicemail. SimulScribe integration doesn't come free though. According to TechCrunch, Ribbit's business plan is to allow users to make PC to PC phone calls for free, but the company will charge a subscription fee for calls to telephones. Users who want to purchase additional services from third parties like SimulScribe will pay an additional fee, although we're sure some add-ons will be offered for free.
