When you provide users with a new feature – be ready for impact. When the calls flow will increased several times – you can easily balance the Flashphoner load, by placing it on multiple servers. Flashphoner load monitored by a special http interface, which issue this statistics of each server on request from your web server. So your load balancer can easily track Flashphoner load statistics and distribute connects for the optimal load blancing.

Yes, except the server side, Flashphoner also has a client applications in complete. There are two kinds of this – Web phone with many buttons, and Click-to-Call button with one “Call button” and predetermined call destination. Both are open source and you can easily change their interfaces and functional. Both have Java Script API.

For many years, organizations around the world to save on phone consultants wages using all the advantages of voice menu (IVR, Interactive Voice Response).

Both of these bundles (Speex-G.711 and Sorenson Spark-H.263) handle by the server side and not loaded the client application.

VoIP telephony market is booming today. And an increasingly competitive is becoming among the VoIP providers. Flash-SIP solution becomes the trump card, which distinguishes one operator from another. Allows user to call directly from the site is going to normal.

What happened?

Lady and gentlements!
Remember day of 8 March, year 2011!
In this day Adobe magically opens a new era of web-telephony.

Why?

Because on March 8 was launched Flash Player 10.3 beta which contains …attention… new Acoustic Echo Cancellation!
And know what? It works perfectly.

Up to this day calls via flash phones were really UGLY, because the flash player had a strong ECHO.
When you speak with someone who used open speakers (laptop, notebook,tablet) – you’ll hear your echo.
And if your partner also uses such a device – huge double screaming echo will burst your ears.

But now everything is different.
Now you can calmly talk through the web fleshphones. Without annoying echo.
You will hear each other and will not hear youself at all.
Now flashphones will be officially used in many business structures and a large number of web-saas services.

Long live the era of web-phones! Hooray!
Ok, lets move forward….

What is the Acoustic Echo?

Acoustic Echo is just like Usual echo, but there is one deffrerence
Usual echo is your own voice, reflected from the walls. It arises in the echoing rooms, caves and mountains
Acoustic echo is your own voice, came from the speakers of your collocutor. It arises when your friend use open dynamics.

Acoustic Echo appeares every time when you use open dynamics.
In some cases, the echo suppressed by desktop phone applications like Skype, Bria and other.

But there is problem with browser Flash applications.
Untill now, Flash does not support real echo cancellation. And if you wanted to make a web phone – you had to implement echo cancellation on the server side. It was very difficult to do technically, and it use a lot of server resources during the further work.

But finally Adobe implement AEC in the Flash Player 10.3 and now this problem solved!
(Check related issue in the Adobe track system)
Acoustic Echo Cancellation feature is bundled with Adobe Flash Player version 10.3 beta and above.
