SIP UserAgent (B2BUA client)——pjsip

SIP UserAgent常用的SIP协议栈有pjsip/bell-sip/sofia-sip/libeXosip/libre等

更方便的是用js来开发网络终端，nodejs开发网络程序非常方便，收集了两个比较好用的

先梳理一下pjsip的应用，sip client一般都处于背靠背的网络环境，需要服务器转接，很多情况还需要网络穿透。

 

 

1、pjsip编译

https://www.pjsip.org

sudo apt-get install libasound2-dev

Linux音频驱动分为alsa和oss，oss是比较旧的驱动，pjsip支持这两种音频驱动，默认是oss，如果目标系统内核使用的是alsa驱动，运行例子程序的时候会出现以下问题。

alsa_dev.c ! ca_thread_func: error reading data!   解决方法 修改config_site.h文件 在pjproject\pjlib\include\pj目录下

增加 #define PJMEDIA_AUDIO_DEV_HAS_ALSA 1 

 

./configure
make dep
make
make instal

编译完就可以直接运行pjsua-x86_64-unknown-linux-gnu测试了

 

2、pjsip移植

1) 移植 alsa-lib-1.1.7.tar.bz2
export ARCH=arm
export CROSS_COMPILE=arm-linux-gnueabihf
tar xjvf alsa-lib-1.1.7.tar.bz2
cd alsa-lib-1.1.7/
./configure --host=arm-linux-gnueabihf CC=arm-linux-gnueabihf-gcc --prefix=/home/dong/alsa-lib-1.1.7/_install
make
make install

2) 移植 alsa-utils-1.1.7.tar.bz2
./configure --host=arm-linux-gnueabihf --prefix=/home/dong/alsa-utils-1.1.7/_install CFLAGS=-I/home/dong/alsa-lib-1.1.7/_install/include LDFLAGS=-L/home/dong/alsa-lib-1.1.7/_install/lib --disable-alsamixer --disable-xmlto
make
sudo make install

3) pjsip交叉编译

./configure --prefix=/home/dong/pjproject-2.8/_install --host=arm-linux-gnueabihf CC=/usr/local/gcc-linaro-arm-linux-gnueabihf/bin/arm-linux-gnueabihf-gcc --disable-libwebrtc CFLAGS=-I/home/dong/alsa-lib-1.1.7/_install/include LDFLAGS=-L/home/dong/alsa-lib-1.1.7/_install/lib
make dep
make
make install

 

下面这些不用管，alsa是同事编译的，gcc也不同，添加了amr转码，作个记录，环境变了容易冲突

1) 移植 alsa-lib-1.1.7.tar.bz2
export ARCH=arm
export CROSS_COMPILE=arm-linux-gnueabihf
tar xjvf alsa-lib-1.1.7.tar.bz2
cd alsa-lib-1.1.7/
./configure --host=arm-linux-gnueabihf CC=/usr/local/arm/gcc-4.9.4-arm-buildroot-linux-gnueabihf/bin/arm-linux-gnueabihf-gcc --prefix=/home/dong/alsa-lib-1.1.7/_install
make
make install

2) 移植 alsa-utils-1.1.7.tar.bz2
./configure --host=arm-linux-gnueabihf CC=/usr/local/arm/gcc-4.9.4-arm-buildroot-linux-gnueabihf/bin/arm-linux-gnueabihf-gcc --prefix=/home/dong/alsa-utils-1.1.7/_install CFLAGS=-I/home/dong/alsa-lib-1.1.7/_install/include LDFLAGS=-L/home/dong/alsa-lib-1.1.7/_install/lib --disable-alsamixer --disable-xmlto
make
sudo make install

3) pjsip交叉编译

./configure --prefix=/home/dong/pjproject-2.8/_install --host=arm-linux-gnueabihf CC=/usr/local/gcc-linaro-arm-linux-gnueabihf/bin/arm-linux-gnueabihf-gcc --disable-libwebrtc CFLAGS=-I/home/dong/alsa-lib-1.1.7/_install/include LDFLAGS=-L/home/dong/alsa-lib-1.1.7/_install/lib
make dep
make
make install

4) opencore-amr交叉编译
./configure --prefix=$(pwd)/_install --host=arm-linux-gnueabihf CC=/usr/local/arm/gcc-4.9.4-arm-buildroot-linux-gnueabihf/bin/arm-linux-gnueabihf-gcc

make

make install


5) pjproject交叉编译
./configure --prefix=/home/dong/pjproject-2.8/_install --host=arm-linux-gnueabihf CC=/usr/local/arm/gcc-4.9.4-arm-buildroot-linux-gnueabihf/bin/arm-linux-gnueabihf-gcc --disable-libwebrtc CFLAGS=-I/home/dong/alsa/include LDFLAGS=-L/home/dong/alsa/lib --with-opencore-amr=$(pwd)/third_party/opencore-amr-0.1.3/_install

make dep

make

make install

 

4) 应用配置

将移植好的alsa-lib-1.1.7_install.tar.gz和alsa-utils-1.1.7_install.tar.gz都解压到/usr/local/qbox10/下

export PATH=$PATH:/usr/local/qbox10/alsa-1.1.7/bin
export LD_LIBRARY_PATH=/usr/local/qbox10/alsa-1.1.7/lib:$LD_LIBRARY_PATH
export ALSA_CONFIG_PATH=/usr/local/qbox10/alsa-1.1.7/share/alsa/alsa.conf

因为编译alsa时路径写死了/home/dong/alsa-lib-1.1.7/_install/

所以录音播音也需要这个路径存放配置文件
mkdir /home/dong
mkdir /home/dong/alsa-lib-1.1.7
mkdir /home/dong/alsa-lib-1.1.7/_install

cp -r /usr/local/qbox10/alsa-1.1.7/share /home/dong/alsa-lib-1.1.7/_install/

5) 录音播音测试
arecord -D "plughw:0,0" -f S16_LE -r 16000 -d 5 -t wav file.wav
aplay file.wav

arecord -d 10 -f cd -r 8000 -c 2 -t wav test.wav
arecord -D "plughw:0,0" -f U16_LE -r 16000 -d 5 -t wav file.wav
arecord -d 10 -t raw -f S16_LE test.pcm
aplay -t raw -c 1 -f S16_LE -r 8000 test.pcm
arecord -d 10 -t raw -f U16_LE test.pcm
aplay -t raw -c 1 -f U16_LE -r 8000 test.pcm
arecord -d 10 -t raw -f U8 test.pcm
aplay -t raw -c 1 -f U8 -r 8000 test.pcm
aplay -t raw -r 8000 test.g711
arecord -D "plughw:0,0" -f U16_LE -r 16000 -d 5 -t wav file.wav
arecord -f S16_LE | aplay -f S16_LE

 

3、pjsua应用实例

pjsua Manual Page

https://www.pjsip.org/pjsua.htm

1) register --- make call
./pjsua-x86_64-unknown-linux-gnu --config-file paul.cfg
m
sip:[email protected]:5060

2) peer to peer
./pjsua-x86_64-unknown-linux-gnu --null-audio
./pjsua-x86_64-unknown-linux-gnu sip:120.78.180.208 --null-audio

3) register cli
>>> +a
Your SIP URL: (empty to cancel):sip:[email protected]:5060
URL of the registrar: (empty to cancel):sip:120.78.180.208:5060
Auth Realm: (empty to cancel): *
Auth Username: (empty to cancel): 100
Auth Password: (empty to cancel): 100
 

sip:[email protected]

 

4) alice.cfg

# This is a comment in the config file.
--id sip:[email protected]:5060
--registrar sip:xx.xxx.xx.236:5060
--realm *
--username alice
--password secret

启动程序，自动应答

./pjsua-arm-unknown-linux-gnueabihf --config-file alice.cfg --auto-answer 200

指定“紧凑模式”（去掉SIP协议的一些非必须的字段），采样率和编码优先级，我在cortex-a5上以默认参数启动，会出现pb和ca线程不同步underrun！

./pjsua-arm-unknown-linux-gnueabihf --config-file alice.cfg --use-compact-form --clock-rate=8000 --add-codec=pcmu --auto-answer 200

其他配置参考官网应用手册https://www.pjsip.org/pjsua.htm

 

5) 临时建群，多方通话

查看pjsua应用手册https://www.pjsip.org/pjsua.htm

的Call Commands和Conference Commands

M

Make multiple calls

Make multiple calls to the same destination.

 

cl	Conference List	List all the ports registered to the conference bridge, and show the interconnection among these ports.
cc	Conference Connect	Create a unidirectional connection between two ports. For example, if you have a WAV player connected at slot #1 and a call connected at slot #2, you can stream WAV file to the call by specifying this command: cc 1 2.

cl查看已拨号的通道， 0是拨号的主叫号码本身，1和2分别是ringback和ring，3和4是被叫号码

M

2

sip:[email protected]:5060

sip:[email protected]:5060

cc 3 4

cc 4 3

 

6) freepbx语音会议

配置好freepbx语音会议后，直接拨号会议号，然后输入密码进入会议室

./pjsua-x86_64-unknown-linux-gnu --config-file 106.cfg --use-compact-form --clock-rate=8000 --add-codec=pcmu --auto-answer 200

也可以自动登陆会议室，auto-conf是自动登陆会议室

./pjsua-x86_64-unknown-linux-gnu --config-file 106.cfg --use-compact-form --clock-rate=8000 --add-codec=pcmu --auto-answer 200 --auto-conf sip:[email protected]:5060

PC/android/ios也是一样的操作

 

 

4、 py_pjsua应用实例

https://trac.pjsip.org/repos/wiki/Py_PJSUA

python实例在pjsip-apps/src/python/samples/

 

5、Python_SIP编译安装
1) ./configure CFLAGS='-O2 -fPIC' --enable-shared
https://trac.pjsip.org/repos/wiki/Python_SIP/Build_Install

 2) pjsua2安装

sudo apt-get install -y software-properties-common # To make add-apt-repository work
sudo add-apt-repository ppa:dennis.guse/sip-tools 
sudo apt-get update 
sudo apt-get install python-pjsua
sudo apt-get install python-pjsua2

To check if everything went well:

python
import pjsua 
https://stackoverflow.com/questions/20195542/python-how-to-get-the-import-pjsua-giving-no-module-named-pjsua

3）Building PJSUA2 and SWIG

The PJSUA2 C++ library will be built by default by PJSIP build system. Standard C++ library is required. If you intend to use Python SWIG module (see below), you need to configure PJSIP with --enable-shared option, i.e.:

./configure --enable-shared make dep & make sudo make install
https://www.pjsip.org/docs/book-latest/html/intro_pjsua2.html#building-python-and-java-swig-modules

装好pjsua2就可以启动pygui测试了拨号了，这个例子带图形界面，ui用的Tkinter，另外一个带gui的例子是vidgui，ui用的qt 

 

 

6、Using OpenCORE AMR NB and WB Codecs

https://trac.pjsip.org/repos/wiki/Using-OpenCORE-AMR-NB-WB-Codec

#opencore-amr 和 vo-amrwbenc
./configure --prefix=$(pwd)/_install --host=arm-linux-gnueabihf CC=/usr/local/arm/gcc-4.9.4-arm-buildroot-linux-gnueabihf/bin/arm-linux-gnueabihf-gcc
make
make install

装好之后将两个库的_install目录合并，合并到opencore-amr-0.1.3/_install

#pjproject
./configure --prefix=/home/dong/pjproject-2.8/_install --host=arm-linux-gnueabihf CC=/usr/local/arm/gcc-4.9.4-arm-buildroot-linux-gnueabihf/bin/arm-linux-gnueabihf-gcc --disable-libwebrtc CFLAGS=-I/home/dong/alsa/include LDFLAGS=-L/home/dong/alsa/lib --with-opencore-amr=$(pwd)/third_party/opencore-amr-0.1.3/_install

make dep
make
make install

 

 ln -s libopencore-amrnb.so.0.0.3 libopencore-amrnb.so.0
 ln -s libopencore-amrwb.so.0.0.3 libopencore-amrwb.so.0
 ln -s libvo-amrwbenc.so.0.0.4 libvo-amrwbenc.so.0
