Flash Player 10.1 and VoIP

Friday, April 16th, 2010

Adding UDP-based RTMFP protocol and Speex audio codec in Flash Player 10 were right moves from Adobe and it allowed us to notice that FP was about to become a good VoIP client. But even with RTMFP capabilities Flash Player couldn’t connect two clients using P2P behind the specific NATs/firewalls, so fallback to server’s relay was required in such cases. With new features of Flash Player 10.1 (RTMFP groups) everything changes, now peers from RTMFP group will help you to do P2P media transfer if direct P2P connection between some 2 peers from the group isn’t possible. If you think a little it will become obvious that FP can be used to create P2P-networks like Skype’s one, root servers will only deal with signaling and will help clients to join groups with peers that can help in media delivery. It can be used in many services. Now we need Acoustic Echo Cancellation support and more advanced video codec for encoding video from webcam (h264, for example) to create web-based Skype.

Flashphone and gtalk2voip

Friday, September 12th, 2008

gtalk2voip

Flashphone is web-based SIP softphone, gtalk2voip is very interesting internet service allows users to:

  • Calling SIP phones and SIP services.
  • Receiving calls to your IM from any SIP phone.

with MSN, gtalk and Yahoo messengers. Both services are free. We’ve made some test calls and found it working very well. For example, if someone is online in Gtalk and you want to call him from flashphone you just need to enter SIP URI like sip:google_username@gtalk2voip.com and gtalk user will see incoming call. You also can easily call to flashphone from gtalk via gtalk2voip, add contact like [flashphone_login]_at_flashphone.ru@gtalk2voip.com and call to this contact, flashphone will ring if user online. If you remember our cool feature - CallMe widget, you can setup your widget to call directly your gtalk messenger if enter appropriate SIP URI as number to call.

P.S. We will continue our work with gtalk2voip to find new interesting features.

Vote for Acoustic Echo Cancellation (AEC) support for Flash player 10 on Adobe jira site

Saturday, May 31st, 2008

As we’ve already written flash player doesn’t support AEC now and even in flash player 10 beta we couldn’t find AEC support. That means that we have to use headset to remove echo problem, but if Adobe implements AEC for flash player we’ll be able to use flash real-time audio communications with loudspeakers. AEC is a very big advantage for VoIP services based on flash technology. Let’s vote for AEC support in Flash Player 10 release version! To vote use the next link: http://bugs.adobe.com/jira/browse/FP-273 , but first you have to register on Adobe’s jira website, using the following link: http://bugs.adobe.com/jira/secure/Signup!default.jspa
