Grandstream 2-FXS Port Analog Telephone Adapter HT802 - Secure VoIP

Our review of the Grandstream HT802 finds it best suited for small offices or home users who need a compact, secure way to connect analog phones to a VoIP service. The single biggest reason to buy is its combination of two FXS ports with support for two SIP profiles and built-in security, which makes the HT802 a simple path to high quality IP telephony without replacing existing handsets. It is compact, supports automated provisioning, and balances advanced features with a straightforward hardware footprint.

Key Features

• Two FXS ports: Allows two analog phones or devices to run separate SIP profiles so users can manage multiple lines from one adapter.
• Single 10/100Mbps port: Provides reliable network connectivity for voice traffic on typical home and small office networks.
• TLS and SRTP security: Protects calls and account credentials with transport layer and media encryption to reduce eavesdropping risk.
• Automated provisioning: Supports TR-069 and XML configuration files so service providers and admins can deploy multiple units with minimal manual setup.
• Ultra-compact design: Small footprint makes the HT802 easy to place in tight spaces or network closets without additional rack space.

Who It's For

The HT802 is ideal for small businesses, remote workers, and residential users who want to keep their analog phones while moving to VoIP services, and for service providers deploying IP voice across many endpoints because of its provisioning options. Its support for two separate SIP profiles makes it useful where two numbers or lines are needed without extra hardware.

Users who require integrated Ethernet switching, multiple LAN ports, or built-in battery backup should look elsewhere, as the HT802 focuses on compactness and basic connectivity rather than advanced routing features or redundant power options.
