• Tries to fix a NullPointerException in CallPeerMediaHandlerSipImpl.createMediaDescriptionsForAnswer reported by Bauersachs Ingo on the dev mailing list in the thread "Exception creating media description when all video codecs disabled".

Other recent changes in earlier versions:

• Don't process NOTIFY messages without subscription state header.

• Fixes IndexOutOfBoundsException in Call History, prevents the gui from crashing in any exceptions coming from contact list filters and adds some logs in order to better analyze the situation, which provoked the exception in first place.

• Fix show of wrong password dialog if we wait too long on master password prompt or wrong password dialog for sip accounts. Fix editing sip account password.

• Rebuilds the native binaries of PortAudio and echo cancellation for Windows, Mac OS X and FreeBSD from r7942. The Windows and FreeBSD binaries are contributed by Sebastien Vincent and the Mac OS X one is courtesy of Damian Minkov.

• Tries to improve the echo cancellation by reducing the effects of reverberation.

• Commits work in progress on improving echo cancellation.Attempts to shorten the adaptation time of the echo cancellation.
• Ensure that the received call dialog is close when the call state changes.

• Fixes a NullPointerException reported by Bauersachs Ingo in the dev mailing list thread "Exception creating media description when all video codecs disabled".

• Commits work in progress on improving echo cancellation.

• Allow to override the preferIPv6Address in the default settings.

• Check which is the default sip transport in default properites.
• Move g722 at first place in the list of preferred codec.
• Commits work in progress on improving echo cancellation. Attempts to better the matching of playback and capture which seems to reduce the far to near end delay. Since the drift is wildly varying, the echo canceller will still fail to deliver. (Which also means that there is no need to rebuild the respective native binaries.)

• Check for client default listen port in the default settings.
• Enable ICE by default, fix javadoc warnings.
• Changes the filter length of the Speex echo canceller to 200 ms. Adds javadocs, renames variables to rename readability.

• Show protocol name in the list of contacts shown in merged contacts, when pressing the call button.

• Fix closing media when Bye has a reason string, fix missed and not overriden method.
• Check local hold state when we compute the direction to set on streams after receiving answer with sdp(invite ok or ack).

• Fix saving volume level.
• Disables the volume control before the call is established.

• Volume control user interface, allowing to adjust volume during a call.
• Source file for the new call history icons.

• Fix login with icq protocol after server changes.

• Close receive streams, even if rtp manager has no receive stream list, due to missing rtcp in media.
• Volume control implementation for media service.
• Enable Jingle to provide audio and video call with XMPP.

• Use size of the video stream in VideoEffect's native code rather than hardcoded 640x480.
