一.编译asterisk和安装Freepbx多处依赖错误
1.configure: error: no acceptable C compiler found in $PATH
解决办法:apt-get install gcc
2.configure: error: C++ preprocessor “/lib/cpp” fails sanity check
解决办法:apt-get install g++或者apt-get install build-essential
3.
configure: *** XML documentation will not be available because the ‘libxml2’ development package is missing.
configure: *** Please run the ‘configure’ script with the ‘–disable-xmldoc’ parameter option
configure: *** or install the ‘libxml2’ development package.
解决办法:安装 libxml2-dev也没用,直接./configure ‘–disable-xmldoc’
4.
configure: error: *** termcap support not found (on modern systems, this typically means the ncurses development package is missing)
解决办法:apt-get install ncurses-dev
5.
[FATAL] PEAR must be install (reauires DB.php). Include path: .:/usr/share/pear:/usr/local/src/PEAR解决办法:pear install db
二.Unknown SQL engine
错误表现:安装完FreePBX后进入admin页面,显示错误:未知数据库引擎.
FATAL ERROR
Unknown SQL engine: []
Trace Back
/var/www/html/admin/common/db_connect.php:57 die_freepbx()
[0]: Unknown SQL engine: []/var/www/html/admin/bootstrap.php:75 require_once()
[0]: /var/www/html/admin/common/db_connect.php/var/www/html/admin/config.php:61 require()
[0]: /var/www/html/admin/bootstrap.php
解决办法:
vi /etc/apache2/httpd.conf
默认是空文件,添加两行
User asterisk
Group asterisk
/etc/init.d/apache2 restart
重启apache后问题解决.
三.Registering 无法注册分机
错误表现:在FreePBX中添加分机后,软电话无法正常注册分机.长时间Registering
解决办法:
执行 asterisk -r 命令,摁s键后tab键,看是否有sip命令.如果没有
则执行module load chan_sip.so,加载sip模块.
重启asterisk后问题解决.
如果不是以上问题,则是asterisk的端口被防火墙封死,执行iptables -F
四.分机之间无法打通电话
错误表现:软电话可以正常注册多个分机.但拨打另一个分机号码后无法打通电话.
执行asterisk -r 打开asterisk控制台
当客户端软电话注册分机时显示如下错误
chan_sip.c:8876 process_sdp: No compatible codecs, not accepting this offer!
解决办法:
在软电话设置中确保selected codecs包含a-law或u-law
或者在FreePBX的分机设置中allow和disallow选项中设置对应的编码格式
