Using the webrtc-internals requires the user to be quite tech-savvy as only few people know how to access the page. Also making the user go to the webrtc-internals page makes the users do a job that should be done by the service provider. With callstats.io integrated in WebRTC service, statistics from every call is periodically logged. Therefore, a developer can dissect segments of a conference call or also search for conference calls made by the same user to see how consistently the issue appears for them.

1. Rich Alternative to
webrtc-internals

2. webrtc-internals
allows participants to
locally observe the
performance of
WebRTC connections

3. eg. chrome://webrtc-internals

4. The page reports on
several network and media
statistics (such as packet
loss, frame rate, and
bitrate, etc.)

webrtc-stats-20150206/

5. But…

6. users do not know that
such a page exists!

7. … and …

8. managing metrics is the
service provider’s
responsibility not the
user’s.

9. Also, webrtc-internals
works only in the
browsers where it
is open.

10. Thus, there is no way to
know how widely spread
the problem is using only
webrtc-internals!

12. Add callstats.js into a
WebRTC service and
callstats.io logs the
metrics periodically in
real-time.

13. callstats.io features
1. Number of calls: successful, failed, relayed.
2. Average of call durations
3. Average setup time and other annoyances
4. Call quality based on transport and
multimedia metrics
5. User feedback about call quality (see our
other blog post)

14. Calls by type

15. Media stream quality

16. Events

17. callstats.io vs. webrtc-
internals
• easier for users and service providers
• real-time data gathering and analytics
• application wide details
