This page explains how channel licensing works in VoIPmonitor, including what constitutes a channel, what happens when you exceed the limit, and how to resolve license lock issues.
This page explains VoIPmonitor channel licensing: what counts as a channel, what happens when limits are exceeded, and how to resolve license issues.


== What is a Channel License? ==
== Understanding Channel Licensing ==


A channel license limits the number of concurrent calls processed by the VoIPmonitor GUI. Commercial licenses are sold with a specific channel cap (e.g., 100, 500, 1000 channels).
=== What is a Channel License? ===
 
A channel license limits concurrent calls processed by the VoIPmonitor GUI. Commercial licenses specify a channel cap (e.g., 100, 500, 1000 channels).
 
{{Note|1='''Key distinction:''' A ''channel'' is a single, un-mergeable CDR leg—not necessarily one logical call. Complex scenarios (transfers, forking, re-invites) can create multiple CDR legs from one conversation.}}


=== What Counts as a Channel? ===
=== What Counts as a Channel? ===


The GUI counts **one channel per call**. For call correlation purposes, the GUI merges CDRs from all legs if the caller and called numbers share at least the last 6 digits.
{| class="wikitable"
|-
! Scenario !! Channels !! Explanation
|-
| Simple call: A → B || 1 || One CDR leg
|-
| Call ending with 487 (Request Terminated) || 0 || Excluded from counting
|-
| Call transfer: A → B → C (creates 2 legs) || 2 || Each un-mergeable leg counts
|-
| Forking/parallel ring || Multiple || One per destination leg
|-
| Same call captured by 2 sensors || 1 || Deduplicated if last 6 digits match (±10s window)
|}
 
'''Deduplication logic:''' The GUI deduplicates CDRs across sensors if the last 6 digits of caller and called numbers match within a ±10-second window. This means geo-redundant captures count as one channel.
 
=== Distributed Deployments ===
 
For multi-sensor architectures:
 
* '''One license covers all sensors''' connecting to a single central GUI+DB
* Channels are aggregated across all sensors, not multiplied per sensor
* Same call captured by multiple sensors is deduplicated automatically


For example:
'''Example:''' Sensors in New York, London, and Tokyo connecting to Frankfurt GUI = ONE license sized for total concurrent calls across all sites.
* Call from 123456001 to 123456002 = 1 channel (caller and called share last 6 digits: 456001 and 456002)
* Call from 123456789 to 987654321 = 1 channel (different numbers do not merge)
* Multiple calls to different phone numbers are counted separately


== What Happens When the License Limit is Exceeded? ==
For deployment details, see [[Sniffer_distributed_architecture|Client-Server Mode]].


When the channel count exceeds your license limit, VoIPmonitor has a grace period before locking:
== License Limit Exceeded ==


1. **3-Day Grace Period:** You can exceed the limit for up to 3 consecutive days without any blocking
=== Timeline ===
2. **Day 4 onwards:** The system begins a lockdown process
3. **After 14 Days:** The GUI locks completely


=== Effects of a Locked GUI ===

When the GUI becomes locked after exceeding the license limit for more than 14 consecutive days:
=== Effects When Locked ===


* **GUI becomes unusable:** You cannot access the web interface

* **CSV exports are blocked:** Data export functionality is disabled
|-
| GUI access, Alerts, Reports, CSV exports || '''Sniffer continues recording all CDRs''' (data is NOT lost)
|}


=== What Still Works During Lock ===
== Resolving License Issues ==


'''Important:''' The sniffer continues to operate normally and record all CDRs to the database even when the GUI is locked. Your call data is not lost.
=== Option 1: Upgrade License (Recommended) ===


== Resolving a License Lock ==
# Log in to [https://www.voipmonitor.org voipmonitor.org] → '''Services''' → '''My services'''
# Click '''UPGRADE''' on your license → select new tier → complete checkout
# Download new <code>key.php</code> and install (see [[#License Key Location|License Key Location]])


To unlock your VoIPmonitor GUI after it has been locked due to license limit overage:
=== Option 2: Self-Service Temporary Increase ===


=== Option 1: Upgrade Your License ===
For immediate relief without contacting support:


The recommended solution is to upgrade to a larger channel license:
# GUI → '''Settings > License'''
# Click '''"Get License Key"''' button
# Receive '''14-day temporary increase'''


1. Contact VoIPmonitor support to upgrade your license to a higher channel limit
{{Tip|The license check considers only the last 3 weeks of call data. After clicking "Get License Key", daily over-limit alerts stop for 14 days.}}
2. Install the new license key
3. Restart the GUI service


=== Option 2: Increase License Limit (Temporary) ===
=== Option 3: Contact Support ===


If you have a higher tier license available but the limit is currently set lower:
Support can:
* Provide temporary channel limit increase
* Investigate incorrect CDR counting
* Issue emergency 30-day trial license (for expired licenses due to billing issues)


1. Update your license key configuration to increase the channel limit
=== Option 4: Delete CDRs (Destructive) ===
2. Restart the GUI service


=== Option 3: Remove and Re-compute CDRs ===
{{Warning|1=This deletes all existing CDRs. Only use as last resort.}}


If you need to quickly unlock the GUI without upgrading:
<syntaxhighlight lang="bash">
systemctl stop voipmonitor
mysql -u root -p voipmonitor -e "TRUNCATE TABLE cdr; TRUNCATE TABLE cdr_next_partition;"
systemctl start voipmonitor
</syntaxhighlight>


To re-process from PCAP files afterward:
<syntaxhighlight lang="bash">
<syntaxhighlight lang="bash">
# WARNING: This will delete all existing CDRs from the database
voipmonitor --config-file /etc/voipmonitor.conf --readpcapdir /var/spool/voipmonitor
# Make sure you have backups or can re-compute from PCAP files
</syntaxhighlight>
 
=== Trial Expiration ===
 
Before purchasing after trial expiration:
 
# Check if license already purchased: voipmonitor.org → '''Services''' → '''My services'''
# If purchased but not applied: Get <code>key.php</code> from order email and install it
# Only if no purchase exists: Buy via GUI (About > Buy License) or portal
 
=== HWID Mismatch Error ===


# Stop VoIPmonitor
'''"license file key.php is for another hwid"''' occurs when hardware ID changed (migration, cloud instance recreation).
systemctl stop voipmonitor
 
'''Solution:''' GUI → '''Settings > License''' → '''"Get License"''' button (auto-syncs with current HWID)
 
'''For frequent cloud instance recreation:''' Request '''domain-based licensing''' from support (binds to domain name instead of hardware ID).
 
=== After License Renewal ===
 
# GUI → '''Settings > License'''
# Click '''"Change license key"''' to expand options
# Click '''"Get license key"''' to fetch updated license
 
'''Manual method:''' Paste full license key (all lines: Expires, easycallerid, hwid, id, maxcalls, upgradeexpire) into the license text field.
 
== Monitoring Usage ==
 
=== Current Status ===
 
Check GUI footer or '''About/License''' page for active channels vs. license limit.
 
=== Historical Data ===
 
'''Tools > Concurrent Calls Stats''' shows maximum concurrent calls for last 14 days (averaged over 60-minute windows).
 
=== Notification Emails ===
 
To disable license notification emails:
 
# GUI → '''Settings > License'''
# Clear the email address field for license notifications
# Save changes


# Connect to MySQL and delete CDRs
{{Note|This only disables license-related emails (warnings, overage, expiration, lock). Other alerts continue normally.}}
mysql -u root -p voipmonitor


# Run these commands in MySQL
== License Key Management ==
TRUNCATE TABLE cdr;
TRUNCATE TABLE cdr_next_partition;
-- Also truncate any cdr_partition_* tables
TRUNCATE TABLE cdr_partition_YYYYMM;
EXIT;


# Restart VoIPmonitor
=== License Key Location ===
systemctl start voipmonitor
</syntaxhighlight>


After deleting the CDRs and restarting, the GUI will recalculate the channel count from the remaining data. If the count is now within the license limit, the GUI will unlock.
<code>/var/www/html/voipmonitor/key.php</code>


'''Note:''' This is a destructive operation. Only use this if you can afford to lose historical CDR data.
=== Transferring to New System ===


=== Option 4: Re-compute CDRs from PCAP Files ===
# Copy <code>key.php</code> from old system to new system
# Restart GUI service


If you have PCAP files in your spool directory, you can re-compute CDRs after making changes:
'''For concurrent operation''' (old + new during migration, or test/dev environments):
* Contact support to configure license for simultaneous multi-server use (preferred)
* Or obtain 30-day trial license for temporary system


<syntaxhighlight lang="bash">
{{Tip|For test/dev servers, contact support to reconfigure your existing license for multiple servers at no extra cost.}}
# Stop VoIPmonitor
systemctl stop voipmonitor


# Delete old CDRs (see Option 3 above)
=== AWS/Cloud Considerations ===


# Re-process PCAP files to regenerate CDRs with the new license settings

|-
! Term !! Meaning
|-
| '''Formal End Date''' || When your paid service period ends
|-
| '''Grace Period''' (20 days after) || For automatic renewal processing only—NOT extended access after cancellation

1. Log in to the VoIPmonitor GUI
{{Warning|1=If you cancel, access ends on the Formal End Date, not the grace period end.}}
2. Check the footer or the **About/License** page (often found under the Gear icon or User menu)
3. Look for **Active channels** vs **License limit**


If you consistently hit the limit during peak hours, consider upgrading your license to avoid lock situations.
'''Emergency access:''' Contact support for 30-day emergency trial license while resolving billing issues.


== License Key File Location ==
== Known Issue: Incorrect Channel Counting ==


The license key file is typically located at:
{{Warning|1=Known bug: Some calls are incorrectly counted as two channels. Confirmed and escalated to development team.}}


<code>/var/www/html/voipmonitor/key.php</code>
'''Symptoms:'''
* License exceeded more frequently than expected
* Tools > Concurrent Calls Stats shows higher peaks than actual call patterns


This file contains your license details including the channel limit. Updates to this file (e.g., when upgrading your license) should be provided by VoIPmonitor support.
'''Workaround:''' Contact support for manual channel limit increase (no upgrade required).

'''Summary:''' VoIPmonitor channel licensing limits the number of concurrent calls processed by the GUI, with licenses sold in channel caps (e.g., 100, 500, 1000 channels). The GUI counts one channel per call, merging CDRs from all legs if caller and called numbers share at least the last 6 digits. What constitutes a channel: one channel per SIP call (concurrent dialog). CDR merging logic: merges all legs if caller and called numbers share the last 6 digits. Exceeding the limit consequences: 3-day grace period allows exceeding limit without block; after 3 consecutive days over limit, lockdown process begins; after 14 days total, GUI locks completely. When locked, GUI, alerts, reports, and CSV exports become unusable. The sniffer continues recording all CDRs to database even while locked (sniffer does NOT stop). Resolution options: (1) Upgrade license to higher channel limit (recommended), (2) Increase license limit if higher tier available, (3) Remove and re-compute CDRs from database (destructive - TRUNCATE TABLE cdr and cdr_next_partition, then restart), (4) Re-compute CDRs from PCAP files using --readpcapdir. Monitor usage: check GUI footer or About/License page (Gear icon or User menu) for Active channels vs License limit.

This page explains VoIPmonitor channel licensing: what counts as a channel, what happens when limits are exceeded, and how to resolve license issues.

Understanding Channel Licensing

What is a Channel License?

A channel license limits concurrent calls processed by the VoIPmonitor GUI. Commercial licenses specify a channel cap (e.g., 100, 500, 1000 channels).

ℹ️ Note: Key distinction: A channel is a single, un-mergeable CDR leg—not necessarily one logical call. Complex scenarios (transfers, forking, re-invites) can create multiple CDR legs from one conversation.

What Counts as a Channel?

Scenario Channels Explanation
Simple call: A → B 1 One CDR leg
Call ending with 487 (Request Terminated) 0 Excluded from counting
Call transfer: A → B → C (creates 2 legs) 2 Each un-mergeable leg counts
Forking/parallel ring Multiple One per destination leg
Same call captured by 2 sensors 1 Deduplicated if last 6 digits match (±10s window)

Deduplication logic: The GUI deduplicates CDRs across sensors if the last 6 digits of caller and called numbers match within a ±10-second window. This means geo-redundant captures count as one channel.

Distributed Deployments

For multi-sensor architectures:

  • One license covers all sensors connecting to a single central GUI+DB
  • Channels are aggregated across all sensors, not multiplied per sensor
  • Same call captured by multiple sensors is deduplicated automatically

Example: Sensors in New York, London, and Tokyo connecting to Frankfurt GUI = ONE license sized for total concurrent calls across all sites.

For deployment details, see Client-Server Mode.

Timeline

Effects When Locked

Blocked Still Working
GUI access, Alerts, Reports, CSV exports Sniffer continues recording all CDRs (data is NOT lost)

Resolving License Issues

Option 1: Upgrade License (Recommended)

  1. Log in to voipmonitor.org → Services → My services
  2. Click UPGRADE on your license → select new tier → complete checkout
  3. Download new key.php and install (see License Key Location)

Option 2: Self-Service Temporary Increase

For immediate relief without contacting support:

  1. GUI → Settings > License
  2. Click "Get License Key" button
  3. Receive 14-day temporary increase

💡 Tip: The license check considers only the last 3 weeks of call data. After clicking "Get License Key", daily over-limit alerts stop for 14 days.

Option 3: Contact Support

Support can:

  • Provide temporary channel limit increase
  • Investigate incorrect CDR counting
  • Issue emergency 30-day trial license (for expired licenses due to billing issues)

Option 4: Delete CDRs (Destructive)

⚠️ Warning: This deletes all existing CDRs. Only use as last resort. 

systemctl stop voipmonitor
mysql -u root -p voipmonitor -e "TRUNCATE TABLE cdr; TRUNCATE TABLE cdr_next_partition;"
systemctl start voipmonitor

To re-process from PCAP files afterward: 

voipmonitor --config-file /etc/voipmonitor.conf --readpcapdir /var/spool/voipmonitor

Trial Expiration

Before purchasing after trial expiration:

  1. Check if license already purchased: voipmonitor.org → Services → My services
  2. If purchased but not applied: Get key.php from order email and install it
  3. Only if no purchase exists: Buy via GUI (About > Buy License) or portal

HWID Mismatch Error

"license file key.php is for another hwid" occurs when hardware ID changed (migration, cloud instance recreation).

Solution: GUI → Settings > License → "Get License" button (auto-syncs with current HWID)

For frequent cloud instance recreation: Request domain-based licensing from support (binds to domain name instead of hardware ID).

After License Renewal

  1. GUI → Settings > License
  2. Click "Change license key" to expand options
  3. Click "Get license key" to fetch updated license

Manual method: Paste full license key (all lines: Expires, easycallerid, hwid, id, maxcalls, upgradeexpire) into the license text field.

Monitoring Usage

Current Status

Check GUI footer or About/License page for active channels vs. license limit.

Historical Data

Tools > Concurrent Calls Stats shows maximum concurrent calls for last 14 days (averaged over 60-minute windows).

Notification Emails

To disable license notification emails:

  1. GUI → Settings > License
  2. Clear the email address field for license notifications
  3. Save changes

ℹ️ Note: This only disables license-related emails (warnings, overage, expiration, lock). Other alerts continue normally.

License Key Management

License Key Location

Transferring to New System

  1. Copy key.php from old system to new system
  2. Restart GUI service

For concurrent operation (old + new during migration, or test/dev environments):

  • Contact support to configure license for simultaneous multi-server use (preferred)
  • Or obtain 30-day trial license for temporary system

💡 Tip: For test/dev servers, contact support to reconfigure your existing license for multiple servers at no extra cost.

AWS/Cloud Considerations

Operation HWID Changes? Action Required
Stop & Start Usually No None
Reboot No None
Terminate & Launch New Yes New license key (use "Get License" button or contact support)
Auto-scaling Group Yes per instance Request domain-based licensing

AWS permission fix (for "Invalid or corrupted hwid" errors): 

chmod 644 /dev/root

Subscription Terms

Term Meaning
Formal End Date When your paid service period ends
Grace Period (20 days after) For automatic renewal processing only—NOT extended access after cancellation

⚠️ Warning: If you cancel, access ends on the Formal End Date, not the grace period end.

Emergency access: Contact support for 30-day emergency trial license while resolving billing issues.

Known Issue: Incorrect Channel Counting

⚠️ Warning: Known bug: Some calls are incorrectly counted as two channels. Confirmed and escalated to development team.

Symptoms:

  • License exceeded more frequently than expected
  • Tools > Concurrent Calls Stats shows higher peaks than actual call patterns

Workaround: Contact support for manual channel limit increase (no upgrade required).
