== Requirements ==

=== !BlackBerry 10 Native SDK === #ndk

You'll need [https://developer.blackberry.com/native/ BlackBerry 10 Native SDK] for native development. After you download and install the SDK, set the environment variables:
 {{{
$ source $BBNDK_DIR/bbndk-env.sh
 }}}

== Configure and Build PJSIP ==

=== Get PJSIP Source Code ===

[wiki:Getting-Started/Download-Source Get the source code], if you haven't already. This tutorial applies to PJSIP version 2.2 and above (or the 2.1 from SVN trunk dated 2013/04/16 or later).

[[BR]]
=== Configure PJSIP ===

 1. Run this in your BB10 NDK directory, otherwise the {{{configure}}} command will fail:
 {{{
$ source $BBNDK_DIR/bbndk-env.sh
 }}}
 1. {{{cd}}} to PJSIP source directory.
 1. (For debug build) Run '''{{{configure-bb10}}}''' script with debugging info and '''without optimization'''. 
 {{{
$ CFLAGS="-O -g" ./configure-bb10 --disable-speex-aec
 }}}
 See Build Customiation section in [wiki:Getting-Started/Autoconf#BuildCustomizations Building with GNU] page or run '''{{{./configure --help}}}''' for more customization info.
 1. We suggest to fill in your '''{{{config_site.h}}}''' ({{{pjlib/include/pj/config-site.h}}} file) with the following:
 {{{
#include <pj/config_site_sample.h>
 }}}
 1. Run {{{make dep}}} to build the dependencies:
 {{{
$ make dep
 }}}


At this point, you may build PJSIP simply by executing '''{{{make}}}''', but we'll show you how to import PJSIP into Momentics IDE and build it from there.


[[BR]]
=== The pjsip.pri QMake Project File === #pjsippri

The {{{configure-bb10}}} script above also creates '''pjsip.pri''' at the root of PJSIP directory. This file contains PJSIP build settings in QMake project (.pro) file format, which can be included in application's '''.pro''' file to build with PJSIP.

See [#newappintegrate creating new app] section for more info.


[[BR]]
=== Import and Build PJSIP to/in Momentics IDE ===

This is optional, as you can just run '''{{{make}}}''' in PJSIP directory to build PJSIP. But nevertheless this is a lot more convenient especially if you are developing PJSIP.

==== Import PJSIP as New Project ====

In Momentics IDE:
 1. Select '''File''' --> '''Import..'''
 1. From the list, open '''!BlackBerry''', select '''Existing Code as !BlackBerry C/C++ Makefile Project''', and click '''Next >'''
 1. In the "Import.." wizard, set
    - Project name: '''pjproject''' (or other name. But in this tutorial we will refer the PJSIP project as ''pjproject'')
    - Code location: the directory where you extract PJSIP to
    - Language: C
    and click '''Next >'''
 1. Accept the default "Use workspace SDK selection", and click '''Finish'''.

==== Create Build Configuration ====

 1. Right click ''pjproject'' from the '''Project Explorer''' view (tab), then select '''Build Configurations''' --> '''Manage''' from the pop-up menu.
 1. In the dialog, click '''New..''' to create new build configuration
    - In "Create New Configuration Dialog":
        - set Name: ''PJSIP-Default''
        - press '''OK''' to close the dialog
 1. Set ''PJSIP-Default'' as the active build configuration by selecting it from the list and pressing the '''Set Active''' button
 1. Press '''OK''' to close the "Manage Configurations" dialog

==== Configure Build Configuration ====

 1. Right click ''pjproject'' from the '''Project Explorer''' view (tab) and select '''Properties''' from the pop-up menu.
 1. In the ''Properties for pjproject'' dialog:
     - Select '''C/C++ Build''' from the left tree pane
     - Make sure ''"PJSIP-Default [Active]"'' Configuration is selected from the combo box in the top center of the dialog.
         - if it's not marked as active, make it active
     - Go to '''Behaviour''' tab
     - Set '''Make build target''' in the textbox right to '''Build on resource save (Auto build)''' to: '''all'''
     - I personally uncheck the '''Build on resource save (Auto build)''' (I'd rather build manually)
     - Also set the build target  in the textbox right to '''Build (Incremental build)''' to: "all"
     - Click '''Apply'''
     - Click '''OK''' to close the dialog

==== Build PJSIP ====

Now you can build the ''pjproject'' PJSIP project.

== Configuring the Device and Momentics IDE ==

For the rest of this tutorial, we will assume that you already have the IDE and target device (or simulator) configured for debugging BB10 native applications. If not, follow [https://developer.blackberry.com/native/documentation/bb10/com.qnx.doc.native_sdk.quickstart/topic/set_up_your_environment.html these instructions] from !BlackBerry developer site.

== Building and Running the pjsua Demo Application ==

PJSIP comes with a fully featured pjsua application which runs on all platforms that PJSIP supports including BB10. 

=== Import the PjsuaBB Project ===

In Momentics IDE:
 1. Select '''File''' --> '''Import..'''
 1. Select '''General''' and '''Existing Projects into Workspace''', and press '''Next >'''
 1. In ''Import..'' dialog:
    - Select root directory: '''{{{$PJ_DIR/pjsip-apps/src/pjsua/bb10}}}'''
 Once you select the directory, '''PjsuaBB''' will appear under ''Projects'' list in the dialog. Make sure it is selected (by default it is). Click '''Finish'''

=== Build PjsuaBB ===

Just build it.

=== Create Debug Configuration ===

 1. Highlight "PjsuaBB" from the Project Navigator, select '''Run''' --> '''Debug Configurations..''' from the main menu
 1. From the left list, right click '''!BlackBerry C/C++ Application''', and select '''New..'''
 1. New debug settings will appear with default values
 1. Go to '''Debugger''' tab and uncheck '''Stop on startup'''
 1. Press '''Apply'''

=== Running PjsuaBB ===

Launch debugging session for PjsuaBB. Wait until the app is loaded on the device. You will see telnet instructions on the device's screen. Telnet to this address to operate the application.

== Creating a New PJSIP Based Application == #newapp

=== Creating a !BlackBerry Native Application === #appconfig

Use Momentics new project wizard to create a new !BlackBerry native application. This should be easy, and we will not explain it here.

Configure the permissions by double-clicking ''bar-descriptor.xml'' file and select ''Application'' tab from the bottom of the page, and check these permissions:
 - Internet
 - Microphone
 - Run When Backgrounded


=== Integrating PJSIP into the App ===  #newappintegrate

Integrating PJSIP settings into the app is very easy:
 1. Open the app's '''.pro''' file (e.g. {{{PjsipBB.pro}}} for PjsipBB app)
 1. Include '''pjsip.pri''' file in the relevant target section, e.g.:
 {{{
..
device {
    CONFIG(debug, debug|release) {
        ..
        include(../../../../pjsip.pri)
        LIBS += -lbb
        ..
    }
}
..
 }}}

The '''pjsip.pri''' file is generated by {{{configure-bb10}}} script (as explained [#pjsippri above]) and contains compilation and link flags to integrate PJSIP with your app. 


[[BR]]

== Simulator ==

Install and configure the BB10 simulator, you will need to install a virtual machine player in order to use the simulator. To build for BB10 simulator, just run {{{configure-bb10}}} script with {{{--simulator}}} option:
 {{{
$ ./configure-bb10 --simulator
 }}}


[[BR]]

== Multiple PJSIP Build Configurations ==

If you want to have multiple PJSIP build configurations for your app (for example, Device-Debug, Device-Release, and/or Simulator), you can use the following approach when building PJSIP.


=== Option 1: Build PJSIP in Multiple Directories ===

This is of course the easiest, just extract or checkout PJSIP in multiple locations, configure it differently, build, and include the right '''pjsip.pri''' file in the relevant section of you application's QMake '''.pro''' file.

=== Option 2: Checkout Once, Configure Build and Install Several Times ===

The second option is to checkout PJSIP in one directory, but configure, build, and install it several times, each with separate build settings and to different install '''{{{--prefix}}}'''. Once the build completes, run {{{make install}}} to install PJSIP development headers and libraries to the installation prefix. You also need to edit the contents of {{{pjsip.pri}}} file, point the path to the right prefix, and rename the {{{pjsip.pri}}} to something more appropriate (e.g. {{{pjsip-device-debug.pri}}}). You then include this .pri file in the relevant section of your application's QMake {{{.pro}}} file.

== Notes ==

=== Missing Separator ===

If you forgot to run '''{{{source bbndk-env.sh}}}''' (as explained [#ndk above]) before running {{{make dep}}}, the dependency files will get corrupted with the ''' "!** missing separator" ''' error and you'll have to delete each of those dependency files manually.

=== GSM Call Interruption Problem === #gsm

If a VoIP call is in progress when an incoming GSM call arrives, and if the user accepts the GSM call, the audio routing of the phone is flawed producing the following result: The VoIP call goes to speaker and the GSM call does not “grab” the audio channels so you get a “null” GSM call and the VoIP call carries on with speaker.

To prevent this from happening, application must implement GSM call detection using BB10 native API, and when it detects a GSM call, it should close PJSIP sound device by using either {{{pjsua_set_null_snd_dev()}}} or {{{pjsua_set_no_snd_dev()}}} and put the VoIP call on hold before accepting the GSM call.

Thank you Bob Cripps of Truphone for the note.

=== Unable to Get Sound Device Parameters === #snd0

This error happens because PJSIP is unable to open the audio capture device. Make sure you set the [#appconfig application permissions] correctly.

=== Troubleshooting !BlackBerry Target Device === #targetprob

 1. Development mode is turned ON (''Settings'' --> ''Security and Privacy'' --> ''Development Mode'')
    - Otherwise when you connect the USB you'll have a random IP address and you are not able to connect to target device in Momentics
 1. You can connect to !BlackBerry target device in Momentics IDE. A !BlackBerry target device will be named something like ''usb'' or ''usb1'' if you're connecting via USB
    - right click the target device in '''Project Explorer''', select '''!BlackBerry Tools''' --> '''Connect'''
    [[BR]]
    If you can't connect, make sure that:
     - the device is really connected
     - it has the right IP address
     - you can ping it (make sure Development Mode is ON)
     - the IP address is correct in Momentics target properties
