Mjsip SIP stack port for Google Android released

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 :-)

We have SIP working on android!

Final update: For folks who are still reaching this post via searches, the [SIPDroid] project took our initial work and have extended it for a full featured application. Instead of downloading our stuff, check them out – their work will be more recent. We (HSC) are not updating our files. Update: April 2 2008: Source code of stack released here Update: Mar 17 2008 See here for a screencast :-) Update: Mar 12 2008 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

A call to report: VoIP ‘geek-talk’ blogs

Update: I have now created a sidebar widget titled “Tech Blogs I read” instead of updating this post. Please continue sending me quality tech blogs (with more focus on concepts and less on marketing) as you come across them and refer to the sidebar for updates and not this post – thx. Total number of ‘market reporting’ VoIP blogs = k+1 where k=number of times you can blink in a day. However, there are very few blogs that talk about more technology & architecture details and less market details for all things VoIP, SIP, IMS, web 2.0 (with focus on telecom). So here is a call to unite! We need a list of what I call ‘geek-talk’ – those that provide more technical insight into how things are. Here is my list so far. Please update me /comment here with more tech-blogs and I will update this list Many of these blogs are a mix of techno-marketing, but are written by people who are neck-deep in actually developing/architecting many of the talked about solutions themselves, and hence offer a more detailed insight. last updated: Apr-30-2008 TurnGeek – focus on P2P, SBC, etc. IMS Lantern – IMS architecture related Voice of

My presentation at the Internet Telephony on IMS, WiMAX and all things nice

I spoke at the Internet Telephony conference in Los Angeles last week on IMS, hWiMAX, how they all work together (or not) and what it really means to applications. You can see a copy here

Speaking at Internet Telephony and our latest IMS report

Hi folks, My apologies for the lack of postings. It just so happens that Sep/Oct/Nov are the worst three months for travel for me. I have been on the road for most part of this month and will be all over the map till the end of November.If any of you are going to be at the Internet Telephony Conference in LA, I hope to see you there. I will be speaking on Monday about “IMS vs. WiMAX” there. So if you are attending, would be good to meet. On another note, I’ve been speaking and attending at the Internet Telephony show for several years now, and I must say, Rich Tehrani and the team has done a great job over the years in being innovative. For this show, as an example, they have come out with innovative interviews, video clips and press releases which help in advertising both their name and the participating company’s name. Good on you, Rich! I hope other setups pick up a bit on the ideas these folks have implemented. On another note, we have just released our July-Aug 2007 IMS Tracking report. You can read an executive brief here. Technology, VoIP, SIP, IMS, Marketing,
