Custom Login

LDAP example

You can find complete LDAP example in GUI directory under scripts/ldap_custom_login_example.php

custom script

Custom login allows to implement your own login mechanism. You need to create file scripts/custom_login.php and function custom_login

custom login script place in: <GUI_INSTALL_DIR>./scripts/custom_login.php

<?php

function custom_login($user, $password) {
        debug_log('custom_login');
        return(array(
                'username' => $user,
                'is_admin' => false,
                'id' => $userIdUniqueNum,       // required numeric unique identifier for each user
//              'id_group' => 1,                // you can set user rights with the gui's group id too
                'enable_sensors' => array(2,3)
        ));
}
?>

The array can return those parameters:

• enable_sensors - array(A,B,...) where the number is number of the sensor. If no enable_sensors provided the user will see all sensors CDR.
• username
• name
• secret
• id_group

CDR HTTP API

This method allows to get CDR rows formatted in JSON which you can see in the WEB GUI using the same filter which you can see in the WGB GUI: Call_Detail_Record_-_CDR#Filter_Form_button

You need to have valid session GUI_automate_login and you have to send those parameters via POST request

For disable authorization (if you are in safe environment) you can use 'GUI->Settings->System Configuration->Disable authorization for API usage' option.

CURL IMPORTANT NOTES

• for entering special characters in curl (e.g. + in caller option) is needed to use -G plus --data-urlencode options

curl -G -X GET 'http://localhost/php/api.php?task=getVoipCalls&user=USER&password=PASSWORD' --data-urlencode 'params=[{"startTime":"2013-01-01","endTime":"2013-08-01","caller":"910251414"},{"startTime":"2013-01-01","endTime":"2013-08-01","caller":"1+1","customHeaders":"Cell-ID-Caller,Cell-ID-Called"}]'

OUTPUT

Output is JSON formated array of CDR

GUI is in default DocumentRoot location

Example for /var/www/html

curl -X POST '192.168.76.201/php/model/sql.php?module=bypass_login&user=voipmonitor&pass=voipmonitor'

returns something like this

{"SID":"ahs2ubdhc0ukb262be60v900ko","cookie_name":"PHPSESSID","success":true,"_vm_version":240034,"_debug":false}

take the SID which you will put to cookie_name variable

Example for /var/www/html/demo

curl -X POST '192.168.76.201/demo/php/model/sql.php?module=bypass_login&user=voipmonitor&pass=voipmonitor'

returns something like this

Example Output for the LISTING task

Please see the attached link output of the API LISTING task

Share CDR

Sharing CDR is possible by sending request to php/model/utilities.php with following parameteres. If you want to share SIP+RTP set type2 to "rtp" and if only SIP set type2:null

show link local public

task=shareCdr&params={"type":"share_cdr_show","type2":null,"subType":"self_protected_link","id":[128024514],"emailFields":null}

show link local private

task=shareCdr&params={"type":"share_cdr_show","type2":null,"subType":"self_login_link","id":[128024514],"emailFields":null}

show link share.voipmonitor.org

task=shareCdr&params={"type":"share_cdr_show","type2":null,"subType":"share_link","id":[128024590],"emailFields":null}

get PCAP file

To get pcap file send GET or POST request with id of the CDR:

http://voipmonitor/php/pcap.php?id=203800251

optinaly RTP can be filtered out by adding parameter disable_rtp=1

Search CDR by URL

If you would like to build URL which will show CDR in web browser matching filter you can use cdr_filter parameter for admin.php

http://localhost/admin.php?cdr_filter={fcallid:"uDR8mtloKFa1F8625VL2OXSFp.RuG73v"}

cdr_filter takes the same arguments like in section WEB_API#CDR_HTTP_API

HTTP API 2

It's preferred. This API was created for getting audio files based on various search criteria. Requests are over HTTP POST or GET.

Rate limit

You can enable it in GUI->Settings->System configuration->API maximal concurrent connections

The limit is set per user.

Check license

• basic test for the license check. It covers the ioncube problems too (e.g. ioncube is not properly installed)

'http://localhost:88/php/apilicensecheck.php?task=licenseCheck'
{"status":1,"message":"license file key.php expired. Current date: 2021-02-23 Expiration date: 2021-02-16"}

'http://localhost:88/php/apilicensecheck.php?task=licenseCheck'
{"status":0,"message":"License OK."}

• test for the concurrent calls limit in the license (required functional ioncube)

'http://localhost:88/php/apilicensecheck.php?task=licenseCallsLimitCheck'

examples of possible outputs:

{"status":1,"message":"You have exceeded the license limit for concurrent calls and the system has been locked. Contact support."}

{"status":1,"message":"You have exceeded the license limit for concurrent calls. The system will be locked in 14 days. Contact support."}

{"status":0,"message":"Limit violation for 2nd consecutive day."}
