Update: Apr 29 2008: UA+Stack code released here
Hey folks, HSC released the android ported mjsip stack source code.
Grab it from here. Look for the attachment to the post titled "Ported GNU Mjsip stack for Google Android"
If you see a "PDF" icon under that post, don't worry, its actually a ZIP with source in it. Our website folks will fix that annoyance soon.
Note that this is a "developer's release". It will allow you to start building applications using the mjsip stack on android. It's not an "automatic solution for long distance calling" (as some blogs reported it) - it is a tool for developers within you to make such applications.
We also have a working SIP UA we ported on top of this stack (which we called 'SIPDroid' - no points for being imaginative here). We are yet to release that port - will do so in a short while.
Note that this is just a SIP stack. There is no RTP included. We did some initial experiments with porting open source RTP stacks - seems very simple. We may just do it later, or you do it and add to this effort :-)
