Video: Google Voice vs Twilio


Google Voice is an alternative telecommunications service. The service is configured and maintained by the user in a web-based application, styled after Google's e-mail service, Gmail. Google Voice currently provides free PC-to-PC voice and video calling worldwide between users of the Google Voice and Video Chat browser plugin
Twilio powers the future of business communications, enabling phones, VoIP, and messaging to be embedded into web, desktop, and mobile software. We take care of the messy telecom hardware and expose a globally available cloud API that developers can interact with to build intelligent & complex communications systems. As your app’s usage scales up or down, Twilio automatically scales with you. You only pay for what you use - no contracts, no shenanigans.

2015 - Cloud communications platform Twilio adds WebRTC video chat. Beware Google Voice


Twilio, the cloud platform, that makes it easy for developers to integrate voice calling and text messaging into their applications, is now also offering a video chat. The new Twilio Video service uses the WebRTC standard — which Twilio already used for some of its audio features — and is now available in beta. What Twilio hopes to enable with this new feature is a future where video can be easily integrated into any application. Say you have an accident and need to call your insurance. With an integrated video feature, you can’t just tell your insurance agent about what happened, but you can show exactly what kind of damage your car sustained. Using Twilio Video, developers get access to multi-party video calls with up to four participants, support for unlimited video connections, low-latency relays through Twilio’s data centers around the world and access to SDKs for iOS and Android.

2011 - GMail VoIP is available almost globally to fight Twilio


VoIP-service in GMail, which was earlier available only in the U.S. and Canada, has appeared in the user accounts in almost all countries of the world - in 38 languages. Here is the list of countries where Gmail Call Phone is NOT currently available: Argentina, China, Cuba, Egypt, Ghana, India, Iran , Jordan, Kenya, Mexico, Morocco, Myanmar, Nigeria, North Korea, Peru, Russian Federation, Saudi Arabia, Senegal, South Korea, Sudan, Syria, Thailand, United Arab Emirates, Viet Nam. With this global intervention, Google has lowered its VoIP rates, making them slightly cheaper than rates of its new main rival - Skype. For example, a call to France costs 8 cents (vs. 16.9 cents in Skype), to USA - 1 (vs. 1.9). As before GMail Call Phone requires quick browser plug-in installation - the same plug-in that is used for video calling in GMail.
