We’re excited to introduce a new security and control feature in the VSM4 Admin Panel under Retail Client Accounts: the ability to define allowed or blocked Caller IDs.This enhancement gives administrators more flexibility when managing how retail accounts can place calls, ensuring tighter control over caller identity and preventing unauthorized use.

How It Works

When configuring prefixes under a retail client account, you’ll now see a new option: Outbound caller ID filtering which allows to restrict Caller IDs. Two modes are available:

1. Allowed Specified

• Admins can define a single Caller ID or a list of Caller IDs.
• Only calls made with these specific Caller IDs will be allowed.
• Any call using a different Caller ID will be rejected.

Use case: Ideal when a retail customer should only make calls using pre-approved numbers.

2. Blocked Specified

• Admins can define one or more Caller IDs that should not be used.
• Any call made with a blocked Caller ID will be rejected.
• Calls using other Caller IDs will go through normally.

Use case: Perfect when you want to block certain Caller IDs while allowing flexibility for others.

Important Note

When this new feature is enabled for an account:

• The Authorize Caller ID option will no longer work, even if Caller IDs are added there.
• All checks will instead be performed exclusively against the Allowed/Blocked Caller ID settings.

This ensures that the system only uses one Caller ID validation method at a time, reducing complexity and avoiding conflicts.

Benefits of Caller ID Restrictions

• ✅ Stronger security – prevent misuse of accounts with unauthorized Caller IDs.
• ✅ More control – admins can fine-tune Caller ID policies per account.
• ✅ Simplified management – no overlap or conflict with the older Authorize Caller ID feature.

With Caller ID restrictions, VSM4 provides administrators with an additional layer of security and flexibility. Whether you need strict control with Allowed IDs only or more freedom with selective Blocked IDs, this new feature ensures you stay in control of Caller ID management for retail accounts.
