Hi all,

I'm really pleased to announce you the first alpha release of a
portage of pjsip for Android : CSipSimple (http://code.google.com/p/csipsimple
)

It's based on the trunk branch (1.x).
And will evolves with updates of the trunk, since for now the aim is
not to have a stable application : there is a lot of work remaining
on the android application itself.

A part of the port was based on the excellent work of Jurij Smakov
(VoiDroid) but I re-wrote the audio driver with new audio-dev API.
(For now audio driver is really minimalistic : only 8KHz and I only
use G711 codec).
I also choose to use pjsip-jni project to glue with java (which I
tweaked a little bit in order to be compliant with the Dalvik JVM).

I will release an apk in next hours for those who want to test. And
i'll also give more information on how to build on http://code.google.com/p/csipsimple/
. It will be also distributed on Google Marketplace and Archos
AppsLib.

Of course, all this work is opensource (released under GPLv3).

For now the build process is deeply linked to the android NDK (a
cross-compil facility toolkit).
But if you are interested, we could imagine to introduce the pjsip
(C) part of my project into a branch of pjsip (or trunk, since it
could be not intrusive just like symbian/wme specific code).

I hope this sounds a good news to you.
I have already a contribution (independent from android port for
pjsua registration module ;) but I'll send it in another post :)....
one thing at time ).

Let me know if you have any remarks or ideas; or if somebody is
interested joining this android project.

Cheers,
Regis. _______________________________________________

Hi Regis,

This is a great achievement, congratulations!

I have one remark, it would make a huge difference compared with existing
SIP clients on mobile if wideband would be supported (g722/speex codecs).

Ok,

So this two codecs will be the first i'll try to build and integrate.

I have already tried to integrate the speex codec but I think that I have
not the good parameters in configuration : I get a metallic voice; so I

postponed the integration of any codec after the alpha release.
I think that the big deal is to properly configure the codec parameters for
mobile. I have to dive into this page I think :
https://trac.pjsip.org/repos/wiki/PJMEDIA-MIPS and also look how they are
configured in symbian and windows mobile.

Is there another referring documentation about codecs configuration?

Metallic voice could be caused by linear resampling, maybe you
upsample from 8 to 16Khz?
