Update: Nov-20-2008: Updated SDK + UA for 1.0 SDK released here. Also released jSTUN port for android here.

Hi folks, as promised, HSC released the ported SIP UA including the stack. This is an update to our previous ’stack only’ release. We have overwritten the old release with this new one in our download area. You can get it from here (look for the post titled “SIP UA + Stack for Google Android).

This release includes a short illustrative manual on how to use the SIP client and some things you need to do to configure it (mostly because of the limitation of the android emulator and what it does(not) support as of the current date). We have also included a ported RTP stack with this release. Theoretically, this release is all set for a signalling + media use case. I say theoretically, because it seems the android emulator does not support audio capture, so everytime one tries to start a media conversation, the emulator crashes. Folks @ the android-dev group have confirmed this is currently not supported in the emulator (but works on their actual phone).

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

Update: April 2 2008: Source code of stack released here 

Hey folks. Enjoy this screencast of a working Android enabled SIP Phone (using mjsip) talking to an X-lite phone.

This is an update to the original “We have SIP working on android” post.

So there you go. It’s real

Some other sites linking here seem to be reporting this news with their own verbiage. Lets be specific on what we are doing:

• We have taken the GPL’d mjsip SIP stack and our objective is to make it work on android (this is mostly a porting activity). We are not writing our own stack.
• We are not doing any optimizations, etc. The scope is exactly what I wrote – make mjsip work on android, so developers can use the mjsip APIs to build apps in android.
• It is a very straighforward ‘take from community (GPL/mjsip), give back to community (post ported code back to GPL/mjsip)’ activity.
• We are targetting to release the port in a week or so… (as-is – as I mentioned the objective is straighforward -a port of mjsip – if it has bugs when you do funky stuff , fix it yourself when we release it )

We (my company) had started an internal project to get SIP working on Android and some smart folks belted out some nifty code to get SIP working on android. We hope to release the ported SIP stack on android pretty soon. We used the GPL’d mjSIP stack and will be releasing the modifications as per GPL, obviously – so other developers have a good SIP API to build apps. This should happen pretty soon. Some time ago, we did a rss-to-presence implementation stub (concept here) over Google Mashup editor. I look forward to seeing the “google-phone” talk SIP to the “google-server” and other cool stuff.

Stay tuned!
