JAIN SIP is working on top of android

[Jean Deruelle]

Hi guys,

Since I got a bit of spare time yesterday night and that I saw that
Android was available in US. I wondered for those that are interested
in building mobile SIP client apps if the jsip stack could run on
android.
And it actually does without any modifications :-)

I ported the Shootme and Shootist examples to android to showcase it.

More details are available here

Wow. 

This is great.

Does this mean that i can build an IMS client using Jsip on top of Android ?? It can be a possibility ! 

Aayush

[Vicky Kak]

Yes you can do that ;)

[aayush bhatnagar]

Hmm great..if something like that can be done. Or maybe JSR 281 APIs
can be clubbed with android to make an IMS client.

[Amit Bhayani]

Can one of us try directly using Sip Communicator, we don't have to reinvent the wheel.

[aayush bhatnagar]

You mean this ? : https://sc-android.dev.java.net/

:)

[Amit Bhayani]

Ahh so its already started, I was referring to original SIP Communicator project.

[Jean Deruelle]

Sip communicator is more than just SIP protocol so a bit more work
might be needed to port it to android.

[Ivelin Ivanov]

Cool, Jean!

Were you able to establish a voice call? Does Android provide access
to the audio input/output in a way that you can connect to RTP
streams?

[aayush bhatnagar]

Speaking of RTP...
http://blog.roychowdhury.org/2008/04/29/sip-ua-for-android-stack-rtp-released/
however, according to this gentleman..the Android emulator crashes
when they try to capture voice.

[Jean Deruelle]

No I just ported the signalling part but I can try to experiment a bit
with the RTP stream now I guess. :-)

[Jean Deruelle]

Yeah it seems Android is not providing a RTP stack so this would need
to be ported. the Media API of Android just allow to play a raw
resource, a file from the system, or from an available network (URL if
the file is capable of progressive download.)
http://code.google.com/android/toolbox/apis/media.html
Since MMS provides an RTP stack and after an offline talk, Amit told
me that it would be possible to make the MMS RTP stack modularized and
externalizable in a standalone jar. Same thing with the codecs. So if
anyone is interested we can put it as an low priority Issue. So please
vote :-)
I vote for it :-) Moreover that this could be also reused for a
standalone standard java sip client if needed.

[aayush bhatnagar]

I vote for it...we won 2-0.

[Jean Deruelle]

lol :-)

Also Android can only record to a file. an API would need to be built
for recording to an RTP stream

[Ivelin Ivanov]

Stream or file? Is it possible to intercept the writing and redirect
to a live RTP stream? Same question for reading.

[Jean Deruelle]

From the API it doesn't look like it's possible
http://code.google.com/android/reference/android/media/MediaRecorder.html
and http://code.google.com/android/reference/android/media/MediaPlayer.html.
But since Google opened it's source code, we should be able to copy
paste and write new APIs to do so.

[thomas]

Hi all,

We have started to develop a SIP/IMS phone a few months ago. We tried
a few SIP stacks and chose JSIP since it worked without any problem.
Media was working fine before Google removed the javasound support
(though the emulator had a few bugs with audio capture). We started
with an in-house basic RTP stack and we think that a modularized MMS
would be very nice. We are now working within the sc-android project.
The main issue at the moment is the Android support for audio in/out.

Anyhow, we are interested to contribute to this kind of project and
also vote for :-)

Hi Thomas,

Thanks for showing interest. can you please point us to your RTP Stack? Is it open source?
The MMS code can be found at http://code.google.com/p/mobicents/source/browse/#svn/trunk/servers/media/core

As of now there is no independent RTP Stack that can be reused out-of-box, but is TODO
You can start with http://code.google.com/p/mobicents/source/browse/#svn/trunk/servers/media/core/server-impl/src/test to understand the architecture and of course forum is helpful.

Amit.

[jean.d...@gmail.com]

I created an Issue so that the RTP Stack can be reused in the future.
See http://code.google.com/p/mobicents/issues/detail?id=436
Contributors are welcome here ! :-)

On a related note : Skype is coming on the Android App Market :-)

[Ivelin Ivanov]

Its starting to get a bit more exciting. Vladimir showed me how Android can run on a Windows Mobile device via boot loader switch, which broadens the Android deploy base quickly.

[aayush]

IMS client for android: http://code.google.com/p/android-ims

[Jean Deruelle]

how do you do that ? any link, tutorials ? it happens I do have a Windows Mobile device...

[Vladimir Ralev]

Well, it has to be an HTC (the android vendor). Most new HTC devices have almost identical hardware to the G1 and it's easy to port. For example http://forum.xda-developers.com/showthread.php?t=402002

[Jean Deruelle]

ok too bad then, Thanks for the link it might prove helpful to someone else out there :-)

[Jean Deruelle]

One gentleman brought to my attention the cupcake branch of android
http://www.google.fr/url?sa=t&source=web&ct=res&cd=3&url=http%3A%2F%2Ftechnologyexpert.blogspot.com%2F2008%2F12%2Fnew-features-coming-to-android-via.html&ei=gjtrSeKVJ5iq-gbVpd2sBw&usg=AFQjCNGyVUiLDuXQEGXYlVZ9MwI7PjgesQ&sig2=M0nIAcNUxp4AOTryKZt-TQ

and it has just been merged in the trunk
http://groups.google.com/group/android-developers/browse_thread/thread/ed7fc8d6265a1a11/0d34ba1c2b0d3632

It seems Android just got Audio I/O Streaming...so a SIP UA with voice support might be able to work now on android...

Exciting. If anyone can setup a working SIP+RTP softphone prototype please post the results here.

[thomas]

Hi all,

We are still very interested to contribute. Our first prototype phone was somewhat frozen due to the removal of audio streaming features from Android. Our RTP stack was rather straightforward (probably too) and I think that having the RTP stack from MMS as an reusable as hinted by Amit is very appealing.
Please let me know if a project (or bootstrap) is available so that we may jump on the wagon.

Cheers,

Thomas

Hi thomas,

there is an issue open to externalize the RTP stack from MMS http://code.google.com/p/mobicents/issues/detail?id=436.
I think that's a nice first step once this is done we can think of porting it to Android.

Adding Earlence Fernandes, a student from India, since he is also interested in developing a prototype SIP UA on Android.

MMS team, could you provide any hints, guildelines, steps or better lead the effort on how to best externalize the RTP stack in another sub maven project ?

Jean

[Oleg Kulikov]

We will move rtp to subproject after CR4 release

excellent, looks like you just got some more resources to help you out :-)
