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

Features

Some of the features of the iPhone port:

• it has 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
• supports for the built-in iLBC codec

Requirements

You'll need an iPhone SDK. We tested mainly with version 3.x SDK/devices, but SDK version 2.x would build fine too. Apple iPad is supported starting with iPhone SDK 3.2.

Build Preparation

1. Get the source code, if you haven't already.
2. 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

Notes:

• 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.
