AGI in “Custom Application”

Variables in Dialplan

Variables are needed to store the information necessary to execute the application.

...

Example 3: Check  if the CALLERID(number) matches a regular expression

GotoIf($[${REGEX("^0[6-7][0-9][0-9][0-9][0-9][0-9][0-9][0-9][0-9]$" ${CALLERID(number)})}]?noanswer,01,1)

...

${CallCount} > 0 - If a count of calls is greater than 0, a call will be routed to the Dialplan procedure.

In case of using MySQL or MSSQL DB, apply one of these custom applications:

...

SayDigits(digits)
Says the digits, one by one, digits can be a variable.

SayNumber(number, gender)
Says number
gender is "f" for female voice; "m" - for male ;"c" - for neutral

Example:

Read(FOO,00000/smartdialplan/numcommande,3,,,10)

SayNumber(${FOO},f)

Dial(SIP/${FOO})

Implementation of Smart Dialplan: limited access to the phone based on the amount of credits purchased

...

After these initial steps it’s necessary to set up “accounting” procedure:

Context 555 (called number 555)

“Custom applications”:

Read(CALLER,00000/accounting/code,,,,10)

(secret code for authentication)

MYSQL(Connect connid support-fr.wildix.com odessa2016-12 oDess@0912to18 odessa2016-12)

MYSQL(Query resultid ${connid} SELECT credit FROM accounting WHERE id=${CALLER})

MYSQL(Fetch fetchid ${resultid} Current_units)

MYSQL(Clear ${resultid})

NoOp(Current Units : ${Current_units})

(connection to the DB and check the number of credits)

GotoIf($[${Current_units} != NULL]?accounting,0,1:accounting,1,1)

(jump to context 1 if code is wrong, else - context 0)

...

You need to:

• Upload PHP AGI (phpagi.sourceforge.net) to /var/www/agi/phpagi/phpagi.php

• Upload test script to /var/www/scripts/test.php

...

Then you can use “remote script” in dialplan, example: Remote script

Microsoft SQL Integration

Create /rw2/var/www/scripts/sqllookup.php

...

Call file Syntax

A simple call file example which dials a number and plays a sound file.

Test.call

-------------------------------------------------------
Channel: SIP/trunkname/18882223333
Application: Playback
Data: 0000/hello-world
-----------------------------------------------------------------

Syntax of call files

• Specify the call destination and the channel to use:

• Channel: <channel>: Channel to use for the call.

• CallerID: "name" <number> Caller ID, please note: it may not work if you do not respect the format: CallerID: "Some Name" <1234>

• MaxRetries: <number> Number of retries before failing (not including the initial attempt, e.g. 0 = total of 1 attempt to make the call). Default is 0.

• RetryTime: <number> Seconds between retries. Default is 300 (5 min).

• WaitTime: <number> Seconds to wait for an answer. Default is 45.

• If the call answers, connect it here:

• Context: <context-name> Context in extensions.conf

• Extension: <ext> Extension definition in extensions.conf

• Priority: <priority> Priority of extension to start with

• Set: Set a variable to be used in the extension logic (example: file1=/tmp/to)

• Application: Application to run (use it instead of specifying context, extension and priority)

• Data: The options to be passed to the application

Use Callfile in dialplan

Create a script file in /var/www/scripts dir.

This script will be executed by dialplan.

Copy a template file and move the duplicated file to /var/spool/callweaver/outgoing/

callfile.sh

------------------------------------------------------
#! /bin/sh
cp /var/www/scripts/test.call /var/www/scripts/temp.call
mv /var/www/scripts/temp.call /var/spool/callweaver/outgoing/
------------------------------------------------------
Give permissions to execute the script.
#chmod +x /var/www/scripts/callfile.sh
Create a template file in /var/www/scripts dir.
Test.call
------------------------------------------------------
Channel: SIP/0276510950/0970720101
Application: Playback
Data: 00000/callfile/message
---------------------------------------------------------

Call a remote script in dialplan.

Use device comment field for customize CID of outgoing call

Set comment in WMS -> Devices for devices:

• Double click on a device to edit it

• Fill out the “Comment” field and click Save

In users dialplan add the following Custom apps:

...

Dial(SIP/0123456789/${EXTEN:3},30,A(00000/Message/Recording) - in this example SIP trunk is used and ${EXTEN:3} removes 3 first digits from the called number.
