Apple iPhone target is supported by PJSIP version 1.6.5 and later.


The iPhone port contains a native CoreAudio based audio device, which supports the following features:

  • the built-in/device's echo canceller
  • output volume setting
  • change input route to bluetooth input
  • change output route
  • input latency setting
  • output latency setting


You'll need an iPhone SDK. We tested mainly with version 3.x SDK/devices, but SDK version 2.x would build fine too.

Build Preparation

  1. Get the source code, if you haven't already.
  2. Please set your config_site.h to the following:
    #define PJ_CONFIG_IPHONE 1
    #include <pj/config_site_sample.h>
    This will activate iPhone specific settings in the config_site_sample.h.

Building PJSIP

Just run:

$ cd /path/to/your/pjsip/dir
$ ./configure-iphone
$ make dep && make clean && make


  • the ./configure-iphone is a wrapper that calls the standard ./configure script with settings suitable for iPhone target.
  • the latest iPhone SDK version will be selected by default. You may change this by setting IPHONESDK environment variable to the desired SDK path.
  • you may pass standard ./configure options to this script too.
  • for more info, run ./configure-iphone --help
  • other customizations are similar to what is explained in Building with GNU page.
