Acceptable Use Policy (AUP)

1. Introduction and Scope

This Acceptable Use Policy ("AUP") defines the acceptable and prohibited uses of the telecommunications services, APIs, networks, and infrastructure provided by CY.TALK SWITZERLAND S.A. ("CY.TALK", "we", "us", or "our").

This AUP applies to all users of our services, including direct end-users, enterprise customers, resellers, API partners, and telecom operators ("Customers"). By using our services, you agree to comply with this AUP. This policy is incorporated by reference into the CY.TALK Terms of Service and any specific enterprise or reseller agreements you may have with us.

2. Prohibited Activities

Customers must not use, or allow others to use, CY.TALK services for any activity that is illegal, fraudulent, abusive, or that violates the rights of any third party. Prohibited activities include, but are not limited to:

• Illegal Content: Transmitting or storing material that violates any applicable local, national, or international law or regulation.
• Infringement: Transmitting material that infringes the intellectual property rights, privacy rights, or other rights of any third party.

• Fraud: Engaging in or facilitating fraud, identity theft, phishing, or financial scams.
• Spam: Transmitting unsolicited commercial communications, bulk emails, or bulk SMS messages without prior consent from the recipient.

3. Telecommunications Abuse

Given the nature of our services, specific telecommunications abuses are strictly prohibited. Customers must not engage in:

• Robocalling: Using automated dialling systems to make unsolicited calls or play pre-recorded messages without explicit prior consent.
• Caller ID Spoofing: Transmitting inaccurate or misleading Caller ID information with the intent to defraud, cause harm, or wrongfully obtain anything of value.
• Traffic Pumping: Engaging in artificial traffic inflation, call generation, or any scheme designed to exploit inter-carrier compensation or revenue-sharing arrangements.
• Toll Fraud: Exploiting vulnerabilities in PBX systems, SIP trunks, or other telecommunications infrastructure to make unauthorised calls.
• Continuous Call Forwarding: Setting up continuous or excessive call forwarding loops that degrade network performance.
• SMS Abuse: Sending SMS messages that violate local regulations regarding sender IDs, opt-out mechanisms, or content restrictions (e.g., adult content, gambling, or unapproved financial services).

4. Network Security and Integrity

Customers must not use CY.TALK services to compromise the security or integrity of any network, system, or application. Prohibited actions include:

• Unauthorised Access: Attempting to access, probe, or connect to any system, network, or account without authorisation.
• Interference: Interfering with service to any user, host, or network, including through denial-of-service (DoS) attacks, mail bombing, or deliberate attempts to overload a system.
• Malicious Code: Distributing viruses, worms, Trojan horses, ransomware, or any other harmful or destructive code.
• Evasion: Attempting to bypass or evade any security controls, authentication mechanisms, or usage limits implemented by CY.TALK.

5. Customer Responsibilities

Customers are responsible for the actions of their own end-users, employees, and agents. If you are a reseller or provide services to third parties using CY.TALK infrastructure, you must:

• Ensure your end-users comply with this AUP or a policy at least as restrictive.
• Promptly investigate and resolve any abuse complaints or AUP violations originating from your network or accounts.
• Maintain adequate security measures on your own equipment, PBX systems, and applications to prevent unauthorised access and toll fraud.

6. Enforcement and Remedies

CY.TALK reserves the right to monitor network traffic and investigate suspected violations of this AUP. If we determine, in our sole discretion, that a violation has occurred, we may take any of the following actions, with or without notice:

• Issue a warning to the Customer.
• Suspend or restrict access to specific services, phone numbers, or API endpoints.
• Suspend or terminate the Customer's account entirely.
• Block traffic to or from specific destinations or IP addresses.
• Report the activity to relevant law enforcement agencies, regulatory bodies, or industry anti-fraud organisations.

CY.TALK shall not be liable for any damages of any nature suffered by any Customer or third party resulting from our exercise of these rights.
