Automatic ADC Transfer Function Lua implementation

I. background:

Although mod_fifo and mod_callcenter can be used as call center applications, it is difficult to customize these two modules in the application, here I use Lua to implement the 5-way Customer Service (1000-1004), a call center number: 9958 ADC implementation solution, which is recorded here.

Ii. flowchart:

Iii. Specific settings:

1. Add/usr/local/freeswitch/CONF/autoload_confilgs/modules. conf. XML to the mod_lua module, which is loaded by default;

2. Add 5 global variables to/usr/local/freeswitch/CONF/var. XML to identify the call status of the customer service number. The content is as follows:

<! -- 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. Add 9958_callcenter.xml in the/usr/local/freeswitch/CONF/dialplan/default directory. The content is as follows:

<Extension name = "yj_callcenter">

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

<Action application = "Lua" Data = "yjcall. Lua"/>

</Condition>

</Extension>

4. Add yjcall. Lua in the/usr/local/freeswitch/scripts directory. The content is as follows:

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 CILS", 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 ();

 

By now, the ADC function has been set up. Call 9958 to implement 5 customer service services.
