VOS3000 Authorization Type Hierarchy: Vital International Domestic Local Net
How does your VOS3000 softswitch decide which destinations a phone is allowed to call? What stops a local-only extension from dialing expensive international numbers? The answer lies in the VOS3000 authorization type hierarchy — a four-tier permission system that controls exactly which call types each phone can make.
According to the official VOS3000 V2.1.9.07 Manual, Section 2.5.2 (Phone Management), the VOS3000 authorization type hierarchy follows a strict precedence rule: International call > Domestic call > Local call > Net call. This means that a phone with International authorization automatically has permission to make Domestic, Local, and Net calls — because the higher authorization level inherently includes all lower levels. Conversely, a phone with only Local authorization cannot make Domestic or International calls, and the call will be banned.

What Is VOS3000 Authorization Type Hierarchy?
The VOS3000 authorization type hierarchy is a permission system that determines which call destination types a phone extension is allowed to reach. Each phone in VOS3000 is assigned an authorization type, and that type governs the entire scope of outbound calling for that extension.
According to the official VOS3000 V2.1.9.07 Manual, Section 2.5.2:
Authorization TypeCall PermissionIncludes Lower Levels International callAll destinations: international, domestic, local, net Yes — Domestic, Local, Net Domestic callDomestic, local, and net destinations Yes — Local, Net Local callLocal and net destinations only Yes — Net Net callInternal/net calls only No lower levels
Key insight: The VOS3000 manual states clearly: “The precedence of authorization is: International call > Domestic call > Local call > Net call.” This hierarchical design means that assigning a higher authorization level automatically grants all lower-level permissions — you never need to assign multiple authorization types to a single phone. The system also states that if a phone lacks the proper authorization to call the type of number specified, “the call will be banned.”
Why VOS3000 Authorization Type Hierarchy Matters
Without properly configured authorization types, several critical problems can arise in your VOS3000 deployment:
Cost overruns: Phones with excessive authorization can dial expensive international routes, causing unexpected billing charges on the associated account
Security risk: Unauthorized international or domestic calling from extensions that should only have local or net access
Billing disputes: When phones can reach destinations beyond their intended scope, account holders dispute charges they did not authorize
Operational inefficiency: Phones with too-restrictive authorization (e.g., Net only when Local is needed) prevent legitimate business calls from completing
Compliance violations: Regulatory requirements in some jurisdictions mandate strict call-type segregation per extension
How Authorization Checks Work in VOS3000
When a phone initiates an outbound call in VOS3000, the softswitch performs an authorization check before routing the call. The billing rate assigned to the phone’s account is used for both billing calculation and authorization verification. This is why the VOS3000 manual specifies that the account’s “Rate of this account will be used to bill and perform authorization checks upon calling.”
VOS3000 Authorization Check Flow:
Phone Initiates Call
│
├── Step 1: Identify destination number type
│ ├── International number (e.g., 00144207…)
│ ├── Domestic number (e.g., 021234…)
│ ├── Local number (e.g., 3456789)
│ └── Net/internal number (e.g., 1001)
│
├── Step 2: Check phone’s authorization type
│ ┌───────────────────────────────────────────────┐
│ │ Phone Authorization: Domestic call │
│ └───────────────────────────────────────────────┘
│
├── Step 3: Compare authorization vs. destination
│ ├── International → BANNED (exceeds Domestic)
│ ├── Domestic → ALLOWED (matches Domestic)
│ ├── Local → ALLOWED (below Domestic)
│ └── Net → ALLOWED (below Domestic)
│
└── Step 4: Route or reject
├── Authorized → Route call, apply billing rate
└── Banned → Reject call, no CDR generated
Important note: The VOS3000 manual specifies that the operator editing the phone number “must have authorizations to manipulate phones of the concerned account.” This means that not only the phone’s authorization type, but also the operator’s administrative authorization level controls which phones can be modified. This dual-layer authorization system ensures that only properly authorized administrators can change call permissions.
VOS3000 Authorization Type — Per-Phone Configuration
The VOS3000 authorization type hierarchy is configured on a per-phone basis in the Phone Management section. Each phone’s authorization type determines its calling scope, and this is managed through the VOS3000 client interface.
According to the VOS3000 Phone Management documentation:
SettingLocationDescriptionAuthorization typePhone Management → Phone settingsSet the phone’s call authorization level: International, Domestic, Local, or NetAccount IDPhone Management → Account assignmentDesignating the billing account for this terminal; rate of this account will be used for authorization checksDefault authorization typeSystem-level default settingCan also set default authorization type for new phones
Configuration workflow: When creating or editing a phone in VOS3000, navigate to the phone management page, select the desired phone, and set the authorization type to the appropriate level. The phone can also be assigned a billing account whose rate will govern both billing and authorization checks. For detailed guidance on account-based billing, see our VOS3000 account billing guide.

VOS3000 Authorization Type Hierarchy — Deployment Scenarios
Different VoIP deployment scenarios require different authorization configurations. Here are recommended authorization assignments based on the VOS3000 manual specifications and common use cases:
Phone User TypeRecommended AuthorizationRationale Executive / Manager International callRequires full calling scope for global business communications; includes all lower authorizations Sales / Regional staff Domestic callNeeds domestic long-distance plus local calling; no international access needed Local office worker Local callOnly requires local area calling and internal net calls; prevents long-distance charges Internal extension only Net callCan only dial other extensions on the same system; no external calls whatsoever Reception / Front desk Domestic callNeeds to transfer incoming calls and make domestic outbound calls for the organization Conference room phone International callMay need to join international conference calls; full authorization ensures no call failures
Best practice: Always assign the minimum authorization level that fulfills the phone user’s requirements. This follows the principle of least privilege and prevents unexpected toll charges. For more on controlling call costs, see our VOS3000 billing system guide and monthly consumption limits reference.
Authorization Type and Account Billing Relationship
The VOS3000 authorization type hierarchy works in conjunction with the phone’s assigned billing account. According to the manual, when an account is designated for a phone terminal, the “Rate of this account will be used to bill and perform authorization checks upon calling.” This means the authorization check is tied to both the phone’s authorization type setting and the account’s billing rate.
ComponentScopeFunctionAuthorization typePer-phone settingDetermines which call destination types the phone can reachAccount billing ratePer-account settingUsed for billing calculation and authorization checks upon callingOperator authorizationPer-operator settingControls which phones the operator can modify; must have authorization to manipulate phones of the concerned account
This three-layer system ensures that: (1) the phone’s authorization type restricts call destinations, (2) the account’s rate governs billing and supplementary authorization checks, and (3) the operator’s permission level controls who can modify phone settings. For complete documentation on account rates, see our VOS3000 billing rating and settlement guide.
Common Authorization Problems and Solutions
Misconfigured authorization types can cause a range of issues in your VOS3000 deployment. Here are the most common problems and their solutions:
Problem 1: Phone Cannot Make International Calls
Symptom: A phone user reports that international calls are rejected or fail, while domestic and local calls work correctly.
Cause: The phone’s authorization type is set to Domestic call or lower, which does not include International call permission. According to the VOS3000 manual, if a phone lacks the proper authorization, “the call will be banned.”
Solutions:
Change the phone’s authorization type to “International call” in Phone Management
Verify the phone’s account ID is correctly assigned — the account rate affects authorization checks
Check that the operator making the change has authorization to manipulate phones of the concerned account
Problem 2: Local Phone Making Unexpected Domestic Calls
Symptom: A phone assigned Local authorization is able to make domestic long-distance calls, resulting in unexpected charges.
Cause: The phone’s authorization type was changed to Domestic or International by another operator, or the account’s billing rate permits domestic calls regardless of the phone’s authorization setting.
Solutions:
Verify the phone’s current authorization type in Phone Management
Check the account audit log for unauthorized authorization type changes
Ensure operator permissions are properly restricted to prevent unauthorized changes
Problem 3: Operator Cannot Modify Phone Authorization
Symptom: An operator attempts to change a phone’s authorization type but receives a permission error or the change does not save.
Cause: The VOS3000 manual specifies that “the operator that edits this number must have authorizations to manipulate phones of the concerned account.” If the operator lacks the appropriate administrative authorization level, the modification will be blocked.
Solutions:
Verify the operator’s authorization level includes phone management permissions
Check the operation authorization settings in user management
An administrator can adjust the operator’s authorization template to grant the necessary permissions

Frequently Asked Questions
What is the VOS3000 authorization type hierarchy?
The VOS3000 authorization type hierarchy defines four levels of call permission for phone extensions, with strict precedence: International call > Domestic call > Local call > Net call. According to the VOS3000 V2.1.9.07 Manual (Section 2.5.2), higher authorization levels inherently include all lower-level permissions. A phone with International authorization can make all call types, while a phone with Net authorization can only make internal calls. If a phone lacks the proper authorization for a destination, “the call will be banned.”
Does a phone with Domestic authorization include Local and Net calls?
Yes. According to the VOS3000 manual’s precedence rule — International call > Domestic call > Local call > Net call — a phone with Domestic call authorization automatically has permission to make Local calls and Net calls. The hierarchy is inclusive: each higher level encompasses all lower levels. You only need to assign the highest authorization level required by the phone user, and all lower-level call permissions are automatically granted.
What happens when a phone tries to call a destination above its authorization level?
According to the VOS3000 manual, if a phone lacks the proper “authorization to call the type of number specified here, the call will be banned.” For example, if a phone has Local call authorization and attempts to dial an international number, the softswitch will reject the call. No CDR is generated for banned calls, and the phone user receives a rejection response. This protects against unauthorized toll charges and ensures call permissions are enforced.
How do I change a phone’s authorization type in VOS3000?
To change a phone’s authorization type: (1) Log in to VOS3000 Client with appropriate operator credentials, (2) Navigate to Phone Management, (3) Select the phone you want to modify, (4) Change the authorization type field to the desired level (International, Domestic, Local, or Net), (5) Save and apply the changes. Note that the VOS3000 manual states “the operator that edits this number must have authorizations to manipulate phones of the concerned account” — so ensure your operator account has the necessary permissions.
Can I assign multiple authorization types to a single phone?
No. Each phone in VOS3000 has exactly one authorization type. Because the VOS3000 authorization type hierarchy is inclusive — higher levels automatically include all lower levels — there is no need to assign multiple types. For example, a phone with International authorization does not need separate Domestic, Local, and Net permissions, because International already encompasses all of them. Simply assign the highest level the phone user requires.
How does the account billing rate relate to phone authorization?
According to the VOS3000 manual, when a phone is assigned an account, the “Rate of this account will be used to bill and perform authorization checks upon calling.” This means the account’s billing rate works together with the phone’s authorization type. The phone’s authorization type controls which destination types are permitted, while the account’s rate determines the billing calculation for permitted calls. Both must be properly configured for correct authorization enforcement and accurate billing. For more details, see our VOS3000 billing rate guide.
