SIP Cordless Handset and Charger

The EnGenius DuraFon-SIP-HC is a ruggedised cordless SIP handset supplied with its charger. It targets facilities that need secure, long-range wireless voice over an existing IP-PBX without deploying dense access-point infrastructure.

Setup Compatibility Check

Verify that your IP-PBX supports the standard SIP protocol and that the 902-928 MHz band is permitted for indoor use in your region. The base station handles up to four concurrent calls, so confirm your trunk capacity matches that limit. Ensure a DC power source is available for the charger cradle.

Build Integration

The handset operates on 128 frequency-hopping channels with 200 kHz spacing, delivering up to 250,000 sq. ft. of in-building coverage and 12-floor penetration from a single base cell. Its 3.7 V 1700 mAh Li-ion battery supports extended shifts, while the 2-way intercom and push-to-talk broadcast features reduce the need for separate paging hardware.
