== Important: Correct API Endpoint Path ==
= VoIPmonitor Web API =


All API requests MUST be sent to the correct endpoint path:
This page documents VoIPmonitor's Web APIs for programmatic access to CDR data, recordings, active calls, and system functions.


*  '''Correct:''' <code>/voipmonitor/php/api.php</code>
== Overview ==
*  '''Incorrect:''' <code>/voipmonitor/api.php</code>


Using the wrong path (missing the <code>/php/</code> directory) will cause API calls to fail with various errors.

If your VoIPmonitor GUI is installed in the default web root (/var/www/html), use:
{| class="wikitable"
curl -X POST 'http://yourserver/php/api.php?task=getVoipCalls&user=USER&password=PASSWORD'
|-
! API !! Endpoint !! Authentication !! Use Case
|-
| '''HTTP API 2''' || <code>/php/api.php</code> || user/password params || CDR queries, recordings, PCAP, active calls
|-
| '''CDR HTTP API''' || <code>/php/model/sql.php</code> || Session cookie || Advanced CDR filtering with GUI filters
|}


If using a subdirectory like /demo:
{{Warning|1='''Correct path is critical:''' Always use <code>/php/api.php</code> (not <code>/api.php</code>). Missing the <code>/php/</code> directory causes "action parameter missing" errors.}}
curl -X POST 'http://yourserver/demo/php/api.php?task=getVoipCalls&user=USER&password=PASSWORD'


== Custom Login ==
== HTTP API 2 ==


VoIPmonitor supports custom authentication mechanisms (such as LDAP) via the <code>custom_login.php</code> script. This script intercepts login requests from the web GUI and allows you to validate credentials against external systems.
Preferred API for programmatic access. Requests via HTTP POST or GET to <code>/php/api.php</code>.


'''Important:''' Web API (HTTP API 2) authentication uses local VoIPmonitor database credentials directly and does NOT use <code>custom_login.php</code> or LDAP authentication. API requests submit <code>user</code> and <code>password</code> parameters that are validated against the local database.
=== Authentication ===


=== LDAP Example ===
Include <code>user</code> and <code>password</code> parameters in every request:


Complete LDAP example available in GUI directory: scripts/ldap_custom_login_example.php.
<syntaxhighlight lang="bash">
curl 'http://server/php/api.php?task=getVoipCalls&user=USER&password=PASSWORD&params=...'
</syntaxhighlight>


Ensure php-ldap package (or equivalent) is installed on the OS hosting the LDAP script.
{{Note|1=API authentication uses local VoIPmonitor database credentials. It does NOT use LDAP or custom_login.php.}}


==== Troubleshooting LDAP Login Issues ====
'''Rate Limiting:''' Enable in GUI > Settings > System Configuration > "API maximal concurrent connections".


If LDAP authentication is working for the local admin user but failing for non-admin users, you can debug the script manually from the command line to isolate LDAP connectivity issues.
=== getVoipCalls ===


===== Step 1: Enable Debug Mode for CLI Testing =====
Retrieve CDR records by search criteria.


Edit the <code>custom_login.php</code> file and **uncomment the debug block** at the top of the script (if present):
'''Parameters:'''
{| class="wikitable"
|-
! Parameter !! Description
|-
| <code>startTime</code> || Calls starting >= this time (required)
|-
| <code>startTimeTo</code> || Calls starting <= this time
|-
| <code>callEnd</code> || Calls ending <= this time
|-
| <code>caller</code> / <code>called</code> || Caller/called number
|-
| <code>callId</code> || SIP Call-ID
|-
| <code>cdrId</code> || Database ID
|-
| <code>id_sensor</code> || Sensor number
|-
| <code>msisdn</code> || Match caller OR called (instead of AND)
|-
| <code>onlyConnected</code> || <code>1</code> = only answered calls
|-
| <code>customHeaders</code> || Comma-separated custom header names to return
|}


<pre>
'''Examples:'''
# debug for manual run
if (!function_exists('debug_log')) {
function debug_log($txt) {
echo $txt . "\n";
}
}
# uncomment next line for test with manual run from command line (php SCRIPTNAME)
custom_login('testuser', 'testpass');
</pre>


===== Step 2: Run Script Manually =====
<syntaxhighlight lang="bash">
# HTTP GET - by time range and caller
curl 'http://server/php/api.php?task=getVoipCalls&user=USER&password=PASSWORD&params={"startTime":"2024-01-01","startTimeTo":"2024-01-31","caller":"123456"}'


Execute the script directly from the command line:
# HTTP POST - by Call-ID
echo '{"task":"getVoipCalls","user":"USER","password":"PASSWORD","params":{"startTime":"2024-01-01","callId":"abc123"}}' | curl -X POST -d @- http://server/php/api.php


<syntaxhighlight lang="bash">
# With custom headers
cd /var/www/html/scripts/
curl -G 'http://server/php/api.php?task=getVoipCalls&user=USER&password=PASSWORD' \
php custom_login.php
  --data-urlencode 'params={"startTime":"2024-01-01","caller":"123","customHeaders":"X-Custom-Header"}'
</syntaxhighlight>
</syntaxhighlight>
'''Response fields:'''
{| class="wikitable"
|-
! Field !! Description
|-
| <code>cdrId</code> || Database CDR ID
|-
| <code>id_sensor</code> || Sensor ID
|-
| <code>calldate</code> / <code>callend</code> || Call start/end time
|-
| <code>duration</code> / <code>connect_duration</code> || Total / connected duration
|-
| <code>caller</code> / <code>called</code> || Caller/called numbers
|-
| <code>sipcallerip</code> / <code>sipcalledip</code> || SIP endpoint IPs
|-
| <code>codec_a</code> / <code>codec_b</code> || Audio codecs
|-
| <code>lastSIPresponseNum</code> || '''(New in 2026.1)''' Final SIP response code (e.g., 200, 404, 503)
|-
| <code>callId</code> || SIP Call-ID
|}
=== getVoiceRecording ===


This will test the script with the hardcoded 'testuser' credentials and output any connection failure messages directly to the console.
Download audio recording (WAV format).
 
===== Step 3: Check LDAP Server Configuration =====


Verify the LDAP server configuration in your script:
'''Parameters:'''
{| class="wikitable"
|-
! Parameter !! Description
|-
| <code>cdrId</code> || Database CDR ID (preferred)
|-
| <code>callId</code> || SIP Call-ID
|-
| <code>calldate</code> || Date hint (default: today)
|-
| <code>zip</code> || <code>true</code> = return ZIP archive
|-
| <code>ogg</code> || <code>true</code> = return OGG format
|-
| <code>saveaudio_afterconnect</code> || <code>"yes"</code> = audio only after call connect
|}


* Check the <code>$ldapsrvs</code> variable contains correct LDAP server IP addresses
'''Examples:'''
* Verify the LDAP server ports are correct and accessible
* Ensure network connectivity exists from the VoIPmonitor server to the LDAP endpoints
 
If the CLI test shows connection failures, verify network connectivity:


<syntaxhighlight lang="bash">
<syntaxhighlight lang="bash">
telnet <ldap_server_ip> <ldap_port>
# By CDR ID
# or
curl 'http://server/php/api.php?task=getVoiceRecording&user=USER&password=PASSWORD&params={"cdrId":12345}' > call.wav
nc -zv <ldap_server_ip> <ldap_port>
</syntaxhighlight>
 
===== Step 4: Verify Required Dependencies =====


Ensure the LDAP PHP extension is installed:
# By Call-ID
 
curl 'http://server/php/api.php?task=getVoiceRecording&user=USER&password=PASSWORD&params={"callId":"abc123"}' > call.wav
<syntaxhighlight lang="bash">
# Debian/Ubuntu
php -m | grep ldap
sudo apt-get install php-ldap


# CentOS/RHEL
# Multiple recordings (returns ZIP)
php -m | grep ldap
echo '{"task":"getVoiceRecording","user":"USER","password":"PASSWORD","params":{"cdrId":[6,7]}}' | php api.php > calls.zip
sudo yum install php-ldap
</syntaxhighlight>
</syntaxhighlight>


===== Step 5: Check User Mapping =====
=== getPCAP ===


The <code>custom_login</code> function must return a valid array containing a required numeric unique identifier (<code>id</code>). If your script successfully authenticates against LDAP but users cannot log in, verify:
Download PCAP file. Automatically merges multiple legs and returns ZIP if needed.


1. The user exists in the VoIPmonitor local database (<code>users</code> table)
'''Parameters:'''
2. The script correctly queries the local database to retrieve the user's ID
{| class="wikitable"
3. The returned array includes the <code>id</code> field
|-
! Parameter !! Description
|-
| <code>cdrId</code> || Database CDR ID
|-
| <code>callId</code> || SIP Call-ID
|-
| <code>cidInterval</code> || Time window (seconds) to search for matching Call-ID
|-
| <code>cidMerge</code> || <code>true</code> = merge multiple legs
|-
| <code>zip</code> || <code>true</code> = force ZIP output
|}


Create users in the GUI (Settings → Users) with the same usernames as in your LDAP directory if you require local user record mapping.
'''Examples:'''


===== Step 6: LDAP Users Cannot View CDRs Despite Being Assigned to Groups =====
<syntaxhighlight lang="bash">
# By CDR ID
curl 'http://server/php/api.php?task=getPCAP&user=USER&password=PASSWORD&params={"cdrId":"12345"}' > call.pcap


If LDAP users can authenticate successfully but cannot view CDRs even though they are assigned to groups with the correct permissions in the GUI, the issue is likely caused by the <code>is_admin</code> flag in your <code>custom_login.php</code> return array.
# By Call-ID with merge
curl -G 'http://server/php/api.php?task=getPCAP&user=USER&password=PASSWORD' \
  --data-urlencode 'params={"callId":"abc123","cidInterval":60,"cidMerge":true}'
</syntaxhighlight>


When <code>is_admin</code> is set to <code>false</code> (the default recommended setting), VoIPmonitor applies the group permissions from the user's local database record. However, if your script incorrectly includes <code>is_admin</code> with any value (even <code>false</code> itself), it may interfere with group-based permission inheritance depending on your specific configuration.
{{Tip|Use <code>curl -G --data-urlencode</code> for complex JSON params to avoid encoding issues.}}


To fix this issue:
=== listActiveCalls ===


1. Ensure your script returns the correct <code>id_group</code> value that matches the group assigned in the GUI Users & Audit section.
Get currently active calls from sensor.


2. Set <code>is_admin</code> to <code>false</code> (or omit it entirely to use default values) to allow group permissions to be applied correctly:
'''Parameters:''' <code>sensorId</code> (optional), <code>callId</code> (optional)
<pre>
return(array(
    'username' => $user,
    'is_admin' => false,  // Allows group permissions to be applied
    'id' => $userIdUniqueNum,
    'id_group' => $groupIdNum,  // Must match GUI group ID
    // ... other parameters
));
</pre>


3. Debug the <code>$groupIdNum</code> variable by running your script manually from the command line:
<syntaxhighlight lang="bash">
<syntaxhighlight lang="bash">
cd /var/www/html/scripts/
curl 'http://server/php/api.php?task=listActiveCalls&user=USER&password=PASSWORD&params={"sensorId":"1"}'
php custom_login.php
</syntaxhighlight>
</syntaxhighlight>
Check the debug output to verify that <code>$groupIdNum</code> is being assigned the correct integer value before the return statement.


4. Implement a fallback mechanism for users without a valid role to prevent login failures. For example:
{{Note|1=IP addresses in response are integers. Convert with <code>INET_NTOA()</code> in MySQL or equivalent in your code.}}
<pre>
if ($groupIdNum === 0){
    debug_log("User $user does not have valid permissions to login, setting the group 1 with low permissions");
    $groupIdNum = 1;
}
</pre>
This ensures users without group mappings can still log in with restricted access rather than being completely blocked.


=== Custom Script ===
=== handleActiveCall ===


Custom login enables implementing your own mechanism. Create file: scripts/custom_login.php with function custom_login.
Pause/unpause RTP recording on active call.


Location: <GUI_INSTALL_DIR>/scripts/custom_login.php
'''Parameters:'''
* <code>sensorId</code> - Sensor number
* <code>command</code> - <code>pausecall</code> or <code>unpausecall</code>
* <code>callRef</code> - Call reference from listActiveCalls


<?php
<syntaxhighlight lang="bash">
function custom_login($user, $password) {
curl 'http://server/php/api.php?task=handleActiveCall&user=USER&password=PASSWORD&params={"sensorId":"1","command":"pausecall","callRef":"0x7f0e4c3c2680"}'
        debug_log('custom_login');
</syntaxhighlight>
        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)
        ));
}
?>

=== Customizing share.voipmonitor.org Domain ===
custom_headers_cdr, custom_headers_message
 
blocked, blocked_reason, req_2fa
To brand the share service with your own domain instead of using the default share.voipmonitor.org, edit the <code>brand.php</code> file in your GUI directory and add the following definitions:
</syntaxhighlight>
 
</div>
<pre>
define('BRAND_SHARESITE', 'share.yourdomain.fr');
define('BRAND_DOMAIN', 'yourdomain.fr');
</pre>
 
Replace 'yourdomain.fr' with your actual domain. This causes share links to use your branded domain instead of share.voipmonitor.org.

=== reportSummary ===
 
Generates a pre-configured summary report as an image. This is the '''only''' type of report available via the web API.
 
'''Important:''' Reports must be created in the GUI before use with the API.
 
====== Report Creation ======
 
Before using this API task:
1. Navigate to '''GUI → Reports → Daily Report'''
2. Create a new report of type ''summary''
3. Fill in the '''Description''' field - this text becomes your '''report_name''' for API calls
4. Configure any charts or filters as needed for the report
5. Save the report
 
The API generates reports that have been pre-configured in the GUI - you cannot create new report configurations via the API.
 
==== Input Data ====
 
task: reportSummary,
user: USER,
password: PASSWORD,
params: {
    report_name: '''the Description field from your GUI report''',
    datetime_from: datetime from (YYYY-MM-DD or YYYY-MM-DD HH:MM:SS)
    datetime_to: datetime to (YYYY-MM-DD or YYYY-MM-DD HH:MM:SS)
    json: true or false (returns JSON response instead of image)
}

===== HTTP GET =====
 
http://localhost/php/api.php?task=reportSummary&user=USER&password=PASSWORD&params={"report_name":"test summary","datetime_from":"2017-12-20","datetime_to":"2017-12-20"}
 
=== getShareURL ===
 
Parameters like getVoiceRecording. Returns public link for LEGs by CID. Use '''callId''' (SIP Call-ID string) or '''cdrId''' (database ID) to identify the call. If 'sip_history' true, only SIP history (RTP ignored).
 
Options: 'anonIps' anonymizes IPs/domains; 'validDays' limits validity.
 
==== Examples ====

'''Summary:''' This article covers VoIPmonitor's custom login (LDAP/script examples, parameters), CDR HTTP API (inputs/outputs, examples), sharing CDRs, getting PCAPs, URL searches, HTTP API 2 (getVoipCalls, recordings, active calls, reports, shares, PCAPs, CDR lists, audio graphs), direct links, SIP history retrieval, and license checks. The LDAP troubleshooting section provides step-by-step instructions for debugging LDAP login issues by testing the custom_login.php script from the command line. A new troubleshooting subsection addresses the specific issue where LDAP users can authenticate but cannot view CDRs despite being assigned to groups with correct permissions, explaining how to properly configure the is_admin flag and id_group variable.
'''Summary:''' VoIPmonitor Web API reference with two main APIs: (1) HTTP API 2 at <code>/php/api.php</code> using user/password authentication for tasks like getVoipCalls, getVoiceRecording, getPCAP, listActiveCalls, getShareURL, handleActiveCall, reportSummary; (2) CDR HTTP API at <code>/php/model/sql.php</code> using session cookies with full GUI filter support. Critical: correct endpoint path is <code>/php/api.php</code> (not <code>/api.php</code>). reportSummary requires pre-configured reports in GUI. Custom login via <code>scripts/custom_login.php</code> enables LDAP/SSO - requires unique numeric ID per user to avoid shared settings. Antivirus may delete scripts with shell_exec - disable with DISABLE_ANTIVIRUS or move to external file. Branding: BRAND_NAME for product name, BRAND_SHARESITE/BRAND_DOMAIN in brand.php for custom share domain.

VoIPmonitor Web API

This page documents VoIPmonitor's Web APIs for programmatic access to CDR data, recordings, active calls, and system functions.

Overview

API Endpoint Authentication Use Case
HTTP API 2 /php/api.php user/password params CDR queries, recordings, PCAP, active calls
CDR HTTP API /php/model/sql.php Session cookie Advanced CDR filtering with GUI filters

⚠️ Warning: Correct path is critical: Always use /php/api.php (not /api.php). Missing the /php/ directory causes "action parameter missing" errors.

HTTP API 2

Preferred API for programmatic access. Requests via HTTP POST or GET to /php/api.php.

Authentication

Include user and password parameters in every request: 

curl 'http://server/php/api.php?task=getVoipCalls&user=USER&password=PASSWORD&params=...'

ℹ️ Note: API authentication uses local VoIPmonitor database credentials. It does NOT use LDAP or custom_login.php.

Rate Limiting: Enable in GUI > Settings > System Configuration > "API maximal concurrent connections".

getVoipCalls

Retrieve CDR records by search criteria.

Parameters:

Parameter Description
startTime Calls starting >= this time (required)
startTimeTo Calls starting <= this time
callEnd Calls ending <= this time

curl 'http://server/php/apilicensecheck.php?task=licenseCheck'

# Concurrent calls limit check
curl 'http://server/php/apilicensecheck.php?task=licenseCallsLimitCheck'

Share CDR Configuration

Share Link Types

Use /php/model/utilities.php with task=shareCdr:

Type subType Description
Local Public self_protected_link Password-protected local link
Local Private self_login_link Requires GUI login
voipmonitor.org share_link Public via share.voipmonitor.org

Custom Branding

Product Name: Edit config/system_configuration.php: 

define('BRAND_NAME', 'YourCompany');

Share Domain: Edit brand.php to use your domain instead of share.voipmonitor.org: 

define('BRAND_SHARESITE', 'share.yourdomain.com');
define('BRAND_DOMAIN', 'yourdomain.com');

Custom Login (LDAP/SSO)

Custom authentication via scripts/custom_login.php. This applies to GUI login only, NOT to API authentication.

Basic Structure

<?php
function custom_login($user, $password) {
    // Authenticate against external system (LDAP, etc.)
    // ...

    return array(
        'username' => $user,
        'id' => $uniqueNumericId,  // REQUIRED: Must be unique per user!
        'is_admin' => false,
        'id_group' => 1,           // Optional: GUI group ID
        'enable_sensors' => array(1,2,3)  // Optional: restrict to sensors
    );
}
?>

⚠️ Warning: The id field MUST be unique per user. If multiple users return the same ID, they share ALL settings (timezone, dashboard, etc.). Use LDAP uidnumber or crc32($email) for uniqueness.

LDAP Example

See scripts/ldap_custom_login_example.php in GUI directory.

Requirements: php-ldap package installed.

Debug from CLI: 

cd /var/www/html/scripts/
php custom_login.php

Enable debug by uncommenting the debug block at top of script.

Troubleshooting

Users share settings: Return unique id per user (see warning above).

LDAP users can't view CDRs: Ensure is_admin => false and correct id_group is returned.

Script being deleted: GUI antivirus deletes scripts with shell_exec(), exec(), etc.

Solutions:

  1. Disable antivirus in config/system_configuration.php:
define('DISABLE_ANTIVIRUS', true);
  1. Or move shell commands to external file outside web directory and require_once() it.

Azure AD / Microsoft SSO

For Microsoft Entra ID integration, see Microsoft_Sign_in_usage. For Google, see Google_Sign_in_usage.

AI Summary for RAG

Summary: VoIPmonitor Web API reference with two main APIs: (1) HTTP API 2 at /php/api.php using user/password authentication for tasks like getVoipCalls, getVoiceRecording, getPCAP, listActiveCalls, getShareURL, handleActiveCall, reportSummary; (2) CDR HTTP API at /php/model/sql.php using session cookies with full GUI filter support. Critical: correct endpoint path is /php/api.php (not /api.php). reportSummary requires pre-configured reports in GUI. Custom login via scripts/custom_login.php enables LDAP/SSO - requires unique numeric ID per user to avoid shared settings. Antivirus may delete scripts with shell_exec - disable with DISABLE_ANTIVIRUS or move to external file. Branding: BRAND_NAME for product name, BRAND_SHARESITE/BRAND_DOMAIN in brand.php for custom share domain.
