Top three free VoIP services

Filed under: voip — Tags: , , , , — miconda @ 7:55 am

Like with emails, some of us prefer to have an independent SIP address, with no relation to current job or location. Being asked several times about free services running Kamailio (OpenSER) or SIP Express Router (SER) – the recently SIP Router project, I am doing a top of my favourite free VoIP providers.

No preference among them, you have to figure out what fits the best for you alone, so I am just listing them in alphabetic order.

ekiga.net

Managed by the author of Ekiga SIP Softphone. Some of the features:

  • peering interconnection
  • presence
  • audio conference
  • address book

iptel.org

Managed by several developers of SIP Express Router (SER). Some of the features:

  • speed dial
  • pstn gateway self provisioning
  • call forward
  • accounting view

voipuser.org

Managed by the founders of VoIPUser.org web forum.

  • UK inbound PSTN number
  • limited outbound calls
  • INum numbers and interconnection
  • peering

Merry Christmas and Happy New Year 2009!

Filed under: openser, voip — Tags: , , , , , — miconda @ 5:01 pm

Day by day, we ended another year. 2008 was full of events, starting with one major release and six minor releases, participation to workshops and conferences wordlwide, adoption in new production environments and acknowledgement of running platforms with millions of users and billions of routed minutes/month using Kamailio (OpenSER), check the News archive at:

http://www.kamailio.org

There were sad events as well, including the hijacking of the old domain name after the rename in Kamailio, still the SourceForge project goes on, with same name, proving the genuine openser project:

https://sourceforge.net/projects/openser/

We maintained release 1.3.x series, last being 1.3.4, which still keeps the old name and is available at:

http://www.openser-project.org/mos/view/News/NewsItem/OpenSER-v1.3.4-Released/

Life is going on, from the the latest major release, version 1.4.0, the project boosted in new features, a summary of what is new since then is available here:

http://www.kamailio.org/dokuwiki/doku.php/features:new-in-1.5.x

An important share of effort was directed to clean the code and improve the stability and performance, a proof of maturity and the need to make the maintenance of the project easier and open for new comers. Lot of documentation was added in doxygen format inside the source code, Devel Guide was published, new developers can start new easier to enhance the application.
Reference moment for the future was the launch of SIP Router project in November – a concentration of many people with great SIP and VoIP expertise, backed up by huge programming experience in this field. This came to strengthen the development workforce, to ensure the reliability, to remove the doubts of what projects is better now or is going to develop better in the future.

So, 2009 is an year that announces already great achievements to be done in its first half:

  • 1st Quarter – release of Kamailio (OpenSER) 1.5.0
  • minor releases for 1.4x and 1.5.x
  • 2nd Quarter – release of SIP Router project as stable version
  • dedicated meeting to celebrate the first operational SIP Router and draw future directions

With the release of SIP Router project, everyone gets access to the features provided by Kamailio (OpenSER), SIP Express Router and OpenIMSCore projects:

Looking forward to a fruitful 2009!

Truphone – Call With Your iPod Touch

Filed under: voip — Tags: , , — miconda @ 3:09 pm

On 4th of December, 2008, Truphone increased its target market, making available their smart VoIP client available for iPod Touch:
http://truphone.blogspot.com/2008/12/turn-your-ipod-touch-into-phone-with.html

… charming and handy to use. Still loyal to my Nokia phone, but the latest developments from Truphone for iPhone and i’Touch are really tempting …

SIP-Router Project Status

Filed under: voip — Tags: , , , — miconda @ 9:43 pm

Just to let you know that on Nov 20, 2008, first openser/kamailio modules run on the common core+tm provided by sip-router project. That was siputils (new module in Kamailio devel version).

Soon after:
– xlog module was ready too, with just an extra define in Makefile, marking the inclusion of pseudo-variable and transformation API in sip-router — one can do color printing via xlog. Note that all pseudo-variables and transformations will be moved in PV module as discussed some time ago on Kamailio devel mailing list.
– db api of Kamailio and SER were included as library and other modules become compilable with sip-router

For reference:
http://lists.sip-router.org/pipermail/sr-dev/2008-November/000071.html
http://lists.sip-router.org/pipermail/sr-dev/2008-November/000077.html
http://lists.sip-router.org/pipermail/sr-dev/2008-November/000081.html
http://lists.sip-router.org/pipermail/sr-dev/2008-November/000082.html

Once MI and statistics will become libraries as well, then many other modules shall work more or less out of the box (some statistics done in core and 1-2 mi commands will miss in the first phase). Then in comesĀ  the second big step, after module integration, config language update — after that point we are kind of 70% ready.

All these happened in just few days since source code repository (GIT) was up … it looks like we will get most of the features from Kamailio/OpenSER and SER together sooner than I expected … let’s see …

Comments to pointed OpenSER project’s issues

Filed under: openser, voip — Tags: , — miconda @ 7:50 pm

Continuing the series of the previous post, these issues were pointed by the person that started the fork from Kamailio (OpenSER). I find none true or consistent. I am pasting here the comments I did on mailing list some days ago.

1) the need for a new reliable release – delayed or low-quality releases are affecting the credibility of the project

http://lists.kamailio.org/pipermail/users/2008-August/018966.html
– the link above shows this one was a faster release than in past
http://www.kamailio.org/mos/view/KAMAILIO-v1.4.0-Released/
– the link above shows the efforts in creating a testing suite which was running on devel server during this development cycle
– the link above shows no much new things in the core, but code cleanup, duplicity removal, source code documentation

2) degradation of the project quality – testing, performance measurements and code quality control are overlooked

– presented before, testing suite was built and running, lot of code was reviewed and improved
– who in the new project (n.r., the new forked project) will do that and couldn’t do it because was blocked in the old project

3) lack of the control, management and coordination of the project – critical project issues could not be handled or solved

– I am not aware of mis-coordinations that could affect the project so badly
– I am not aware of critical issues that could not be solved and there was no report of a critical deadlock
– if there was a failure in management, all from the board share same fault

Moreover, I believe there are facts in the past that openser took care of its quality. I repeat as I said that QA might not be enough no matter is done. If openser 1.3.x is the core component of a platform hosting about 2 millions of subscribers does not ensure some QA, then nothing else can be said, see:
http://www.ilocus.com/2008/03/the_largest_voip_offering_base.html

None above motivates such reactions as happened recently, but if does, then probably with some openess and discussions everything would have been better now.

Worth to link here the board discussions minutes:

About the fork from OpenSER

Filed under: openser, voip — Tags: , — miconda @ 6:16 pm

Being one of the founders of OpenSER, involved deep in the management and development, I was (still am) asked about my position regarding the fork from OpenSER, so I am quoting here my email sent to mailing lists few days after.

As an update, the Kamailio project continues OpenSER and has already many new features:
http://openser.blogspot.com/2008/10/towards-kamailio-v150.html

<quote>
Following the last events (n.r. fork from OpenSER project) everybody perhaps wonders what is going on. I was surprised by the way everything happens and I am not sure yet how this resulted.

Probably a bit of time is needed to clarify relations between developers themselves and community as well. There is not any official statement that a developer quited the support for this project, but I guess the trust between some is at lowest level possible.

It is clear that we cannot say anything about a board right now that manages the project. From board discussions summary you may see that discussions were conducted to create a legal entity around the project, a non profit foundation. This might be hard to achieve in this status, but as a personal decision, I am not going in any other management group unless there is a legal framework backing up. Human relations prove to be pretty unpredictable and not conforming with initial statements.

What is sure now – openser 1.3.x and 1.4.x will be maintained properly and I am volunteering to take care but hope others will join. It is really a good achievement of a sip server. Decision about future development will be based on community and developers feedback for this project. I am not going to promise anything by myself as I admit one person (to be more specific: myself) cannot take care of the entire code base — I am just realistic, not willing to sell dreams. I think the people that still believe in the project can come with suggestions and alternatives of future development.

What I can tell for sure, I am not going to join a fork of the original openser project. If something happened to make developers not working together, solution to solve nicely could have been found, in the worst, maybe just by splitting teams, but keeping old domain together just to show the new alternatives.

“Why not joining a fork in this manner?” Because I was one of the founders of this one and involved in development and management at top level. If I failed to build something I started, I had all the tools in my hands, why just creating something similar saying the old is crap but this new one will be the best? What is the difference? Why I didn’t do it first time? Would I be able to fool someone? Does leaving my ship in secrecy on back door will bring more trust on me? I doubt and perhaps you, too.

I am certainly assuming share of the failure in managing this project. I was there, in management, period. There is no single person responsible for mis-management, but it comes just easy for some to blame the others. But I am really confident we built outstanding sip server, all of us contributed with code, documentation, testing to an application that routes million and millions of minutes per day. There were accuses of bad things about project, I will argument in a separate message, this will get too long.

Truphone and iPhone

Filed under: voip — Tags: , , — miconda @ 3:04 pm

Truphone, UK-based VoIP Mobile operator, has announced the iPhone version of their application. I am a heavy user of Truphone during travelings, on my Nokia phone. Now that iPhone ships 3G version and I can have Truphone reachability, it might be a time to get into the Apple world.

Truphone Anywhere

Filed under: openser, voip — Tags: , , — miconda @ 11:44 am

Just returned from a drive trip to Berlin, for Asterisk Tag and Linux Tag 2008 (see some comments at http://www.asipto.com/index.php/2008/06/04/remarks-asterisktag-and-linuxtag-2008/), I am catching up with latest VoIP news.

Interesting for me is the launch of TruphoneAnywhere, a new service from the UK-based VoIP mobile operator Truphone that allow you to do check calls from your mobile even if you are not connected to WiFi. These guys are going to reduce my phone bill a lot — last month I was 90% of the time in roaming. See here some price comparisons:
