SIP support and more in the Internet communications software update for developers

Nokia has announced the development version release of the Internet Communications Software Update for maemo 3.2. This update brings you the latest developments in Internet messaging and call destined for the next Internet Tablet OS release.

The software release is under development and therefore is not suitable for end users and serious personal use. However, if you are interested in helping improve it, the update should be fairly usable and we encourage to try it.

What is it?

Internet Communications Software is a subsystem in the Internet tablet OS 2007 and running on the Nokia N800 that handles presence, chat, VoIP and video call. It is based on Telepathy framework and components as explained at http://telepathy.freedesktop.org/

Limitations

UI

SIP

• Calls fail to establish media streams when the device is behind a symmetric NAT and the proxies do not deploy transparent media relaying.
• Calls forked to multiple endpoints may fail to establish media streams.
• Video is not interoperable with other implementations.
• DTMF (RFC4733) is not reliable.
