The product is a software license for the use of SIP-TLS (Session Initiation Protocol over Transport Layer Security) in small VoIP gateways from the Patton SmartNode series SN200 and SN500. This license enables encrypted signaling over the SIP protocol, thereby enhancing the security of communication between VoIP devices and services. The license is intended for resale and does not include any transfer of copyright. It serves exclusively to activate the SIP-TLS function in compatible Patton devices and is not delivered as a physical unit.

Applications
The SIP-TLS license is designed for businesses and service providers who require secure VoIP communication over public networks or insecure IP connections. It is particularly used in environments where the confidentiality of signaling (e.g., call setup, number transmission) is important. The license is suitable for small VoIP gateways offered in the SmartNode series SN200 and SN500, and supports integration into existing IP telephony infrastructures.

Features and Specifications in Detail
The license activates encryption of SIP signaling using TLS, a standard for secure data transmission over the Internet. This protects communication control (e.g., call setup, termination, number transmission) from eavesdropping and manipulation. Encryption occurs at the transport layer, ensuring SIP messages are protected during transmission. The license is not associated with any physical components and is activated via the Patton management interface or a corresponding software platform.

Technology Explained Simply
SIP-TLS means that signaling—i.e., the control of VoIP connections—takes place over an encrypted connection. This is especially important when VoIP devices communicate over public networks or insecure IP connections. Encryption is performed using TLS, an established protocol for secure data transmission also used in web browsers and email systems. The license enables activation of this security feature in compatible Patton devices without requiring additional hardware.

Compatibility and Accessories
The license is specifically designed for Patton SmartNode devices from the SN200 and SN500 series. Compatible devices include, for example, the SmartNode 4141, SmartNode 4151, and SmartNode 4131 models, available in various configurations with BRI or FXS interfaces and different VoIP channel counts. The license can be used in combination with these gateways to encrypt SIP signaling. No physical accessories are included with this license; it is purely software-based.

Installation and Mounting
The license is not physically mounted but activated via the software platform of the Patton device. Installation is performed through the gateway’s management interface, where the license key must be entered. The exact procedure depends on the firmware version used and is described in the documentation for the respective device. No special mounting work or hardware modifications are required.

Operational Benefits
Using the SIP-TLS license enhances the security of VoIP communication by encrypting signaling. This protects against unauthorized access to call data, such as phone numbers or call times. The license is easy to activate and requires no additional hardware. It is particularly advantageous in environments where communication occurs over insecure networks, such as mobile or remote connections. The license is not linked to any physical components and is not included in the delivery scope; it must be purchased and activated separately.
