Plivo (YC S12) Launches the first SDK that connects WebRTC And SIP

It should be embarrassing for TC when the first comment on their story points out their mistake-

"""The first? Phono (http://phono.com/webrtc) has been doing this for nearly a year now on Canary and now Chrome, even won in the best WebRTC tool class at the WebRTC conference in the San Francisco Bay Area late last year. Further, AT&T announced their Call Management API where Ericsson did the same thing in Las Vegas using their IMS (which is all SIP BTW):

Congratulations to Plivo, great to see more folks entering the WebRTC space. But would be great to see just a tiny bit of research done by folks at Techcrunch before declaring firsts."""

Switching from Twilio to Plivo was one of the best decisions we made at our company. Glad to see Plivo keeping up the innovation and progress :)

Same here!

After this incident - http://news.ycombinator.com/item?id=4866677 - we gave it a try and its now in production!

Why? What improved?

I used to work for Twilio. Their Twilio Client JavaScript SDK has supported WebRTC for two months now. You can use it to connect to the PSTN or SIP addresses. http://www.twilio.com/blog/2012/11/webrtc-for-twilio-client-...

As I said in another comment, I should know better than to expect simple fact-checking from a TC author. But somehow I'm still disappointed.

Glad you brought this out. Plivo not only allows calling out to SIP addresses, but also allows any SIP Device (hardphone, softphone) to call to a WebRTC endpoint.

I am not sure, how the SDK you mentioned here would allow you to do that as Twilio does not support inbound SIP. And thats why the TC article says its a first!

Be,

Are you also passing video or just audio for now?

Also, are you doing any encryption on the signalling or media? Great job rapidly iterating and building new products. Always nice to see innovation in the voice apps business.

From the SDK example it looks like I am supposed to put my Plivo credentials in plain text in JavaScript. Am I missing something? Because that seems like a really terrible idea.

The credentials can be generated dynamically from any server side language like php, python or ruby and sent to the js. Once the call is done or after a certain time these credential can be deleted using server side APIs too.

Edit:

Creating an Endpoint - http://plivo.com/docs/api/endpoint/#create

Deleting an Endpoint - http://plivo.com/docs/api/endpoint/#delete

I see. So I can create an endpoint on the server when the page is generated, give it a random password, and drop that into the page. And then to expire it I would have some background process that deletes endpoints n minutes after they are created or something?

Speaking of webrtc and sip just try sipml5.org I've just tested it with asterisk 11.2.0 and after a bit of fighting I was able to make it works (I'm not affiliated).

Almost ended up working for the fine fellows at Plivo. Very smart and very ambitious guys. This is likely only the start. Keep up the good work!

Excited to integrate SIP, PSTN and WebRTC. Any docs?

Funny. I get a warning from chrome that tc is showing content from d.adsbyisocket.com which seems to dangerous. Anyone else?

yeah.. something funny with chrome..

i'd say something funny with tc...

yep..

this is pretty great, I wonder what Twilio is doing in response

Twilio already has a WebRTC bridge to SIP and the PSTN with its Twilio Client SDK. I should know better, but I'm actually disappointed at the complete lack of fact-checking in this TC article.

Stanley, Plivo not only allows calling out to SIP addresses, but also allows any SIP Device (hardphone, softphone) to call to a WebRTC endpoint. I am not sure, how the SDK you mentioned here would allow you to do that as Twilio does not support inbound SIP. And thats why the TC article says its a first!
