Benny Prijono — Wed, 09 Nov 2011 08:51:36 +0000

This release contains significant features and bug fixes that we’ve done in the past six months. Highlights of the release include:

support for iOS5 build,
support for OpenCORE AMR-NB codec,
a new pjsua_destroy2() API for faster shutdown, and
many many bug fixes including crashes and deadlocks

Version 2.0-alpha2 is released

Benny Prijono — Mon, 10 Oct 2011 07:47:23 +0000

Version 2.0-alpha is released, yay! We planned to put the last API changes in this release, so after this there will be no more API change (fingers crossed!) and we can focus on more testing for the betas.

There is a significant API change in the codec and some important new APIs on this release, please click on the links below for more info:

codec API has been changed. The new one should be easier to use.
API base support for video orientation.
API support for native preview.
API support for fast device switching (e.g. switch from front to rear camera).

Also there is a new useful utility called sipecho in the samples. More on that later.

Now, go straight to download page to get the latest release!

Cheers!

pjsip for BlackBerry PlayBook: Native SIP client may be closer than you think

Perry Ismangil — Sat, 23 Jul 2011 14:37:23 +0000

One of the most frequently ask questions we got is: does pjsip support BlackBerry? Are there plans to do so?

We always answered no, because the current BlackBerry devices only supports Java and even then there seem to be lack of multimedia access (essential for audio/video capture and playback) and direct socket access (for media streaming).

Recently however, with the BlackBerry Playbook using a different operating system, they have also announced that native C/C++ development kit will be available later this year.

So, maybe it will be not long now until we can answer ‘Yes’. Well, at least it can run on the BlackBerry PlayBook, if not all their smartphones.

SVN URL for version 1.x has been moved to a branch

Benny Prijono — Fri, 06 May 2011 07:16:54 +0000

With the release of PJSIP version 1.10, the svn repository for version 1.x has been moved from trunk to a new branch:

http://svn.pjsip.org/repos/pjproject/branches/1.x

If you are monitoring the SVN trunk version, please switch your repository to the URL above. This can be done easily by running the following command in your work directory:

$ svn switch http://svn.pjsip.org/repos/pjproject/branches/1.x

Later we will put 2.0 development into the svn trunk, but for now, we have equipped the svn trunk with a build error to make people aware that the location has been changed.

Thanks!

Version 1.10 is released

Benny Prijono — Fri, 06 May 2011 06:51:39 +0000

PJSIP version 1.10 has just been released! There are several usable enhancements as well as few important bug fixes on this release, for more information please see the Release Notes. As usual, source packages are available from the Download page.

PJSIP 1.8.10 released with SIP outbound support

Benny Prijono — Tue, 07 Dec 2010 09:19:01 +0000

PJSIP 1.8.10 is released! As we’re currently busy with other development (namely, video for the upcoming 2.0; more on that later), we didn’t plan to put new features into this release indeed.

But still one new feature is worth mentioning. During our SIPit27 visit, we discovered that there are three proxy implementations that support SIP outbound extension (RFC 5626). We’ve always wanted to implement SIP outbound, because it’s very useful for NAT traversal, and the lack of support in the server side was the only thing that held us back. So this convinced us to write the extension on site, in time for successful participation in SIP outbound multiparty test on the event.

So that is the highlight of this release, namely SIP outbound support and one week worth of heavy QA at SIPit 27. Enjoy!

Version 1.8.5 is released

Benny Prijono — Thu, 21 Oct 2010 05:23:56 +0000

Version 1.8.5 is released, containing some bug fixes and incremental enhancements from previous releases. Please see the Download page as usual for more info.

Benny Prijono — Thu, 16 Sep 2010 09:45:31 +0000

PJSIP version 1.8 has been released which adds iPhone/iPad iOS4 multitasking/background feature support into the library. For more info, please see the Release Notes from the Download page.

PJSIP version 1.7 adds iPhone and multipart support

Benny Prijono — Wed, 11 Aug 2010 13:10:29 +0000

PJSIP version 1.7 has been released, with two major features added, namely official PJSIP support for iOS (iPhone/iPad/iPod touch devices) and support for multipart message bodies. The iOS port added native CoreAudio audio device implementation usable for both Mac OS X and iOS, and it also utilizes the device’s built-in echo cancellation feature for more robust echo cancellation. The port also added built-in iLBC codec that comes with the device.

This version also fixed many bugs, part of which discovered during the last SIPIT 26 in Sweden.

Please see the usual download page for more info.

PJNATH ICE Heap Memory Usage Analyzed and Optimized

Benny Prijono — Sat, 05 Jun 2010 09:00:08 +0000

A new article was posted in PJSIP wiki: PJNATH ICE Heap Usage Analysis and Optimization, that shows how to optimize ICE heap memory usage, from around 76 KB of peak heap usage per call (or 25 KB after the call settles down), down to just 21 KB of peak heap usage per call (or 15 KB after the call settles down). And this was with STUN, ICE, and TURN enabled.

PJSIP version 1.6 is released

Migration of svn and Trac: expect disruption

Perry Ismangil — Wed, 17 Feb 2010 10:54:10 +0000

We are currently migrating svn and trac to new hosting provider, so svn.pjsip.org and trac.pjsip.org will be disrupted for a little while.

Sorry for any inconvenience.

[Update: Everything should back to normal now. As a bonus, https connections are now properly certified without warnings! Yay!]

pjsip version 1.5 is released with TLS Rewrite, TLS for Symbian, QoS, and MWI Support

Benny Prijono — Thu, 26 Nov 2009 03:42:37 +0000

Version 1.5 has just been released with the following features.

SSL/TLS Rewrite

A new secure socket abstraction is implemented in PJLIB. The API is implemented using the native CSecureSocket for Symbian platform and OpenSSL for other platforms. With this API, new type of implementations (such as native Windows SSPI) could be written in the future.

The SIP TLS transport has been rewritten to make use of this secure socket API, while maintaining the existing SIP TLS transport API. The secure socket API will also make way for other SSL/TLS based transports in the future, such as TLS TURN client connection.

QoS Framework

All transports in the library (such as SIP UDP/TCP/TLS transports, UDP media transport, and STUN/TURN/ICE transports) have been equipped with QoS (Quality of Service) settings. The QoS framework abstracts QoS technologies such as the Type of Service/DiffServ Code Point (ToS/DSCP) fields, Wi-Fi Multimedia (WMM) priorities, and IEEE 802.1p tagging (via SO_PRIORITY) in a generic manner, while providing flexibility for applications to adjust the settings manually if wanted.

The QoS framework has been tested on Symbian, Windows Mobile 6, Linux, and MacOS X. Note that currently it is not available on Windows XP and later.

Please see the new QoS wiki page for more info.

Message Summary/Message Waiting Indication (MWI) Support

Added support for both subscription based MWI (RFC 3842) and unsolicited MWI that is used by a popular PBX. For more information please see ticket #982.

Presence Enhancements

Ticket #937 among other things implemented automatic buddy’s presence resubscription upon receiving several specific termination causes. Ticket #411 and #364 improved the PUBLISH request handling.

SIP INVITE/CANCEL Destination Fixes

Ticket #917 and #936 fixed the following problems:

CANCEL request may be sent to different server than the INVITE when DNS SRV is used
INVITE request retry because of 401/407 response may be sent to different server than the INVITE when DNS SRV is used
CANCEL request will be sent with UDP if the INVITE was sent with TCP because of 1300 bytes message size/MTU limit (it must be sent with the same transport)

Please get the new version from PJSIP download page as usual.
