SwitchCoder - Telephony Platform without API

SwitchCoder is kind of like Twilio, but without the RESTful APIs.

Instead, they provide a javascript engine for you to write your code.

This javascript way of using telephony service is not new. Tropo has implemented that for a long time.

Their pricing is fairly similar to Twilio, Tropo, Plivio (and a dozen):

• 1 cent per minute
• 1 cent per SMS
• $0.50 per phone number

TelAPI - Another telephony API like Twilio

TelAPI is out of beta today.

TelAPI is like Twilio, a product for developers to easily create voice/sms apps. The features they offer is largely similar. Pricing also the same.

There is only one unique feature I see:

• Voice and audio effects

They support TwiML (Twilio proprietary XML syntax to instruct the call flow) AND also Restful web API. Cool if you don't have to know the TwiML.

Phono SDK Makes Call From Your Web Browser

Phono provides an SDK to make calls from your web browser. To be more specific, they provide a javascript library that is easy to integrate into a web development.

It is now using flash technology (for mic), but WebRTC is coming soon (as they claimed).

Phono is not the only library that does voice call from a web browser. Twilio Client is another one.

TalkSpace let you call between users for free

Create a TalkSpace (aka a conference room), and let participants talk for free!

The API/SDK can be used for iOS clients, or even Facebook platform. So if you are developing on these platforms, throw in the SDK and let your users chatter!
