# Phone by Cubilock

### Overview

Phone by Cubilock (CubiCall) is an enterprise-grade dialer designed to enforce carrier and regional compliance policies through deterministic call barring. The app intelligently intercepts both inbound and outbound calls at the telecom layer and cross-references them against centrally managed allow/block rules before the connection is established. This ensures that regulated devices remain aligned with organizational compliance requirements at all times.

### Key Features

#### Dual-Direction Call Barring

Take complete control over both incoming and outgoing call traffic with independent rule sets tailored to your organization's needs. Phone by Cubilock supports:

* **Whitelist-only dialing** — Restrict calls to pre-approved numbers only
* **Blacklist enforcement** — Block specific numbers or patterns
* **Hybrid rules** — Combine country-level restrictions with number-specific rules for maximum flexibility

Each direction operates independently, allowing you to enforce different policies for inbound and outbound calls.

#### Granular Number Controls

Maintain detailed white lists and black lists directly through the admin console. The system provides:

* **Detailed visibility** — Tap through to see every enforced number in the system
* **Compliance tracking** — Keep a complete record of all call restrictions

#### Country-Level Governance

Enforce compliance at the country level without managing individual numbers. Switch between two modes:

* **"Allow only"** — Permit calls only to specified countries
* **"Block these regions"** — Allow all calls except those to blocked countries

Sync your compliance profile from headquarters, and the app automatically applies the appropriate country-level restrictions.

#### Offline-Ready Enforcement

Your devices continue to enforce compliance policies even when they're offline. Phone by Cubilock:

* **Caches the latest policy set locally** — No connectivity required to block calls
* **Continues enforcement offline** — Maintains all call restrictions without network access
* **Auto-syncs on reconnection** — Automatically updates policies when connectivity returns
* **Zero compliance gaps** — Never exposes devices to policy violations due to connectivity issues
