ADC自动转接功能Lua实现

一、背景介绍:

  虽然使用Mod_fifo和mod_callcenter可以做呼叫中心的应用,但在实现应用中,这两个模块很难客制化需求,再此我用Lua实现了5路客服(1000-1004),一个呼叫中心号码:9958 的ADC实施方案,谨在此记录。

二、流程图:

ADC自动转接功能Lua实现

三、具体设定:

  1 .  /usr/local/freeswitch/conf/autoload_confilgs/modules.conf.xml 中加在 mod_lua模块,默认是加载的;

  2.  在/usr/local/freeswitch/conf/var.xml 中添加5个全局变量,标识客服号码通话状态,内容如下:

           <!-- yjCallCenter Sets: 0 allow the call, 1 busy -->

            <X-PRE-PROCESS cmd="set" data="yj1000=0"/>

            <X-PRE-PROCESS cmd="set" data="yj1001=0"/>

           <X-PRE-PROCESS cmd="set" data="yj1002=0"/>

           <X-PRE-PROCESS cmd="set" data="yj1003=0"/>

          <X-PRE-PROCESS cmd="set" data="yj1004=0"/>

  3.  在/usr/local/freeswitch/conf/dialplan/default 目录下添加 9958_callcenter.xml ,内容如下:

     <extension name="yj_callcenter">

         <condition field="destination_number" expression="^(9958)$">

           <action application="lua" data="yjcall.lua"/>

         </condition>

      </extension>

  4.  在/usr/local/freeswitch/scripts 目录下添加yjcall.lua,内容如下:

    print("\n*******logo_fox's CallCenter******\n")

    api=freeswitch.API();

    local yj1000= freeswitch.getGlobalVariable("yj1000");

    local yj1001= freeswitch.getGlobalVariable("yj1001");

      local yj1002= freeswitch.getGlobalVariable("yj1002");

    local yj1003= freeswitch.getGlobalVariable("yj1003");

    local yj1004= freeswitch.getGlobalVariable("yj1004");

    function yjCheck(command,lineNum,info)

       local yjdata=api:executeString(command);

        local i1,j1=string.find(yjdata,"100"..lineNum);

        if(info=="LineStatusCheck") then

           if(i1~=nil  and  i1>0) then

              api:executeString("global_setvar yj100"..lineNum.."=1");

        else

        api:executeString("global_setvar yj100"..lineNum.."=0");

         end

      end

        if(info=="RegistionCheck") then

             if(i1~=nil  and  i1>0) then

              return 1;

          else

               return 0;

        end

     end

    end

    local L1000=yjCheck("sofia status profile internal reg",0,"RegistionCheck");

    local L1001=yjCheck("sofia status profile internal reg",1,"RegistionCheck");

    local L1002=yjCheck("sofia status profile internal reg",2,"RegistionCheck");

    local L1003=yjCheck("sofia status profile internal reg",3,"RegistionCheck");

    local L1004=yjCheck("sofia status profile internal reg",4,"RegistionCheck");

    for  i=0,4,1 do

     yjCheck("show calls",i,"LineStatusCheck");

    end

    yj1000= freeswitch.getGlobalVariable("yj1000");

    yj1001= freeswitch.getGlobalVariable("yj1001");

    yj1002= freeswitch.getGlobalVariable("yj1002");

    yj1003= freeswitch.getGlobalVariable("yj1003");

    yj1004= freeswitch.getGlobalVariable("yj1004");

    if(yj1000=="0" and L1000==1) then

    print("------Customer 1000 is at your service------");

     api:executeString("global_setvar yj1000=1");

      session:transfer("1000","xml","default");

         return;

    end

    if(yj1001=="0" and L1001==1) then

       print("------Customer 1001 is at your service------");

      api:executeString("global_setvar yj1001=1");

     session:transfer("1001","xml","default");

      return;

    end

    if(yj1002=="0" and L1002==1) then

     print("------Customer 1002 is at your service------");

      api:executeString("global_setvar yj1002=1");

      session:transfer("1002","xml","default");

      return;

    end

    if(yj1003=="0" and L1003==1) then

     print("------Customer 1003 is at your service------");

      api:executeString("global_setvar yj1003=1");

       session:transfer("1003","xml","default");

      return;

    end

    if(yj1004=="0" and L1004==1) then

    print("------Customer 1004 is at your service------");

     api:executeString("global_setvar yj1004=1");

       session:transfer("1004","xml","default");

      return;

    end

    print("---------No available line, please wait dial!!----------");

    session:hangup();

  到此,ADC功能已经设定完毕,呼叫9958即可实现5路客服的服务。
