About me

I’m Carlos Ruiz-Díaz, a telecommunications developer from Paraguay living in Mexico City.

In late 2014 I founded a startup called Toky which became a success but not without numerous struggles in the middle. This blog is about the learnings I took from this experience.

If you want to get in touch with me, send me a DM on Twitter @caruizdiaz.

  2. Hello.
    My name is Rodion.
    I use WebRTC to receive calls in browser. I use JsSIP library on frontend (Chrome browser). And I use Asterisk + Kamailio on backend. In updated Chrome version 47 there were some WebRTC improvements and changes.
    Now when I make outgoing calls in my system everything works fine. But when I receive incoming calls there is no sound from caller and callee. Caller can’t hear the voice from the other side and the same is for callee. There is no error messages in browser console and on backend. There is no any warning messages even.
    In the previous versions of Chrome (46) everything works fine. I see the same sip logging messages in Chrome 45, 46 and 47. Everything looks the same. But I have that issue with no sound during incoming calls in browser while using Chrome 47.

    I spent more than 10 days trying to solve this issue… And I can’t solve it. May be you can help me to solve the issue? To advice something to force it back to work in Chrome 47?

    Thank you, Rodion
