Telefonica’s Tu Go service turns to WebRTC for in-browser calls

The Spanish carrier group Telefónica is big on WebRTC, the technology that allows for plugin-free in-browser voice and video calls, among other things – it uses it for the in-browser Skype rival that’s built into Firefox these days, for example. So it’s no surprise to see the firm turn to WebRTC to power the next generation of its Tu Go service, which extends Telefónica/O2/Movistar’s services from the mobile network to Wi-Fi.

Whereas the desktop Tu Go client has so far been a discrete affair, it can now be accessed from within the browser, as long as that browser supports WebRTC – so far, Chrome and Firefox apparently offer the best experience. There’s no need to download anything extra and, as with the new Reach Me feature in rival Orange’s Libon app, this provides another way to take and make calls using your normal mobile phone number even when there’s no reception (Libon doesn’t require you to be an Orange customer, though).

The service bases its experience on conversation timelines and is designed to make it easy to continue conversations across devices. Tu Go for Web also makes it possible to conduct up to five conversations at once, which sounds technically impressive if somewhat mentally taxing.

One more thing to keep an eye out for: Telefónica is experimenting with integrating Tu Go with IFTTT so, for example, incoming SMSes could be automatically saved in Evernote or incoming calls from specific people could change the color of your home’s lighting as an alert.

When Tu Go came out a couple years back, I said Telefónica had pulled off the rare trick of creating unique value in a carrier-backed “over-the-top” (OTT) app — rather than just trying to cannibalize its own mobile services with an OTT rival. It is using the internet to extend that core service to new devices. It’s good to see the company still playing around with new ideas that this IP-based world makes possible.

Tu Go for Web is available now to O2 customers in the U.K. and Movistar customers in Argentina. It will also soon roll out to Peru, Mexico and Brazil, which are entirely new markets for Tu Go.
