FreeSWITCH 1.2.12 Released

Submitted by mcollins on Thu, 07/25/2013 - 22:55

We are pleased to announce that FreeSWITCH version 1.2.12 has been released! Ken's mailing list post details some of the changes and contains any follow up conversations regarding this release.
What's new in this release? Lots and lots of bug fixes. 1.2.12 is now the recommended FreeSWITCH version for production environments. As usual, test it with your configuration prior to migrating a production server.
As of this writing the CDN has been purged so you can download the latest source tarballs and RPMs. Naturally the git repo is tagged already. The DEB files are coming soon.
Thanks for all your help in making FreeSWITCH get better and better.

Welcome to July!

We've had lot's of great news lately with FreeSWITCH and now there's even more. Our friends at Yealink have reported on a very large VoIP installation in Spain that utilizes Yealink phones and FreeSWITCH servers. The complete writeup can be found here. We look forward to reporting on more success stories in the future.

With the recent announcement about FreeSWITCH 1.4 beta and WebRTC support there has been a lot of interest in just how to make this all work. On this week's conference call we will be taking a closer look at the code and showing you how to setup both sides of a WebRTC connection with FreeSWITCH. Please join usthis Wednesday at 1PM Eastern, 10AM Pacific for this interesting discussion.

We also had an interesting discussion on last week's conference call. Lorenzo Magani and Alexandr Dubovikov from the HOMER project gave us a tour of their new version 3.5 release. The HOMER SIP capture system is an excellent - and free - tool that can be put into production with any FreeSWITCH server. HOMER is an invaluable tool used for SIP diagnostics and troubleshooting and we highly recommend it for anyone using FreeSWITCH and SIP in a production environment.

Have a great week and we'll talk to you on Wednesday.

FreeSWITCH Project Releases Version 1.4 Beta with WebRTC Media Support

Submitted by mcollins on Wed, 06/19/2013 - 18:36

The FreeSWITCH team is very proud to announce that FreeSWITCH 1.4 beta is now available. The community will benefit greatly from all of the effort that has gone into producing a version of FreeSWITCH that supports WebRTC media streams.
WebRTC is a technology poised for explosive growth. By some estimates, there will be three billion WebRTC-enabled devices and endpoints by 2016. Having this new technology in FreeSWITCH will ensure that developers and users will always have a robust platform on which to build solutions that can utilize WebRTC, VoIP, and traditional telephony. Additionally, FreeSWITCH allows these solutions to be built completely with FOSS technologies.

We would like to take time to thank the following sponsors who helped make the new FreeSWITCH possible:

We appreciate companies like these as well as individuals who work very hard to make sure that FreeSWITCH continues to innovate while remaining free software.

Happy 2nd week of June to everyone.

We want to remind everyone that on June 19th we will be releasing the ClueCon 2013 schedule on the FreeSWITCH community conference call, so please be there. As an added bonus the whole FreeSWITCH dev team will be on hand and hanging out with the community.
On occasion we like to acknowledge community members who've stepped up and made a difference in a way that benefits the FreeSWITCH project as a whole as well as those who use it. Our friend Call Leeming has been doing a great job of doing triage on the FreeSWITCH bug tracker. In fact, just today he reported on checking five Jira tickets. We appreciate these efforts and we encourage everyone to take a few moments to peruse the open tickets and look for items where they can assist, even if it's merely testing the validity of a bug report. Thank you to everyone who helps out.

After having open community discussions these past few weeks we will have a formal presentation this week by yours truly. In response to numerous requests we have decided to do a demonstration of the CudaTel Communication Server. I will be giving a tour of the CudaTel user interface and we will be glad to answer questions. I think you will be impressed with the hard work that the core FreeSWITCH team has put into building the CudaTel.

We look forward to talking to you on Wednesday.

FreeSWITCH Weekly News and Notes - New Book is Out!

Submitted by mcollins on Tue, 05/28/2013 - 16:59

Happy Tuesday to you all! It is a short week for us here in the U.S. as yesterday was a national holiday.

The first order of business: I am happy to let you know that Packt Publishing has informed us that the new FreeSWITCH 1.2 book is available as of May 24th! Congrats to the FreeSWITCH team for getting yet another book ublished. This is the third one we've done with Packt. Also, many thanks to all those who spent time answering questions and helping us with the technical reviewing process.

With the new book completed we focus our attention on other things, not the least of which is ClueCon 2013. Starting this week, those who've submitted talk proposals will be receiving the official acceptance of their presentations, including the day and time for the presentation. If you have not already submitted a talk proposal please do so right away as we have a limited number of available speaking slots.

Our weekly conference calls have been lively with discussions on various topics suggested by those calling in. On last week's call we had a particularly nice discussion about mod_skinny. A relatively new community member, Nathan Neulinger, has really done a nice job of picking up the torch for mod_skinny. If you have a need to use Cisco phones with FreeSWITCH using SCCP then definitely listen to last week's discussion.

This week we have Martin from the project. We look forward to learning more about VoIPMonitor and how it can help us with keeping tabs on our VoIP servers.

Have a great week!

The FreeSWITCH team is busy on several fronts but the most exciting news at the moment is that Packt Publishing has told us the new book is officially off to production! If all goes well it should be available in the next few weeks. (It looks like they changed the cover art - once we know for sure what's on the cover we'll give it a nickname like we did with the "bridge" book.)

Last week we had an impromptu discussion on various FreeSWITCH topics. We have rescheduled the conference call presentation for May 29th. Also, we have tentatively scheduled the HOMER presentation for June 5. That means we will have another open discussion for this Wednesday's conference call.
As a tip, if you would like to browse around and see what has been committed in FreeSWITCH lately you can use the Fisheye site. Here you can browse the source code and look at recent commits to see what has changed. If you prefer to look at the commits without the source code browser then try out the HTML front-end for our FreeSWITCH git repository. We also have repositories for contributions and sample configuration sets.

Have a great week!

A belated happy new week to you all!

As Ken mentioned in his email yesterday, the big news from last week is, of course, the release of FreeSWITCH 1.2.9 stable. This is now the "latest stable" version of FreeSWITCH and the one most recommended for production use. The tarball is available from theusual location. The CentOS and Debian packages have also been updated to use the latest stable. 

On last week's conference call we welcomed Dan from the CGRateS project. CGRateS is a relatively new project that handles call rating for carrier-grade operations. We are happy to have CGRateS (an open-source project itself) as part of the FreeSWITCH ecosystem.

On this week's call we look at another VoIP-related OSS project: This software performs a number of monitoring functions for VoIP implementations. Please join us tomorrow at 1PM EDT, 10AM PDT for an interesting discussion. 

One ClueCon reminder: We are still accepting speaking proposals, however time is running out so please send them in as soon as possible. We hope to have the ClueCon 2013 schedule released in the next few weeks.

Take care and have a great week!

Happy first May Monday to all.

We are please to let everyone know that the new FreeSWITCH book is nearing completion. Each day the Packt editors have been sending us revised and re-revised chapters to polish off. If we keep up our current pace then it is quite likely the book will be available in early June. We hope you enjoy it.

On last week's call we enjoyed a nice presentation from Omar over at OrecX who showed us some of the useful features of their call recording
solutions. They have an open source version as well as commercial versions. If you are looking for a call recording solution then we recommend that you review what OrecX has to offer.

This week we continue in our series of presentations on FreeSWITCH-compatible software applications. We look forward to having Dan Bogos from CGRateS join us to talk about their project. Click here to get a quick look at what CGRateS does, and then make plans to join our call on Wednesday.
Regarding ClueCon 2013 we would like to remind everyone that we are still accepting talk proposals. If you have a talk idea please let us know. In the meantime feel free to get registered and book your hotel room at the Hyatt.

Have a great week!
