Product Description
The NS-T20 sip paging gateway offers a streamlined solution for migrating analog audio systems to IP-based platforms with user-friendly operation. This efficient ip paging gateway features integrated volume control buttons and a single PoE network interface, providing straightforward setup and operation. The analog audio interfaces - including MIC input for dynamic microphones, speaker output for 15W passive speakers, and headset jack - allow direct connection to existing analog equipment such as ceiling speakers, horn speakers, and amplifier inputs. It is engineered for environments requiring simple yet reliable IP audio integration.
Equipped with advanced audio processing capabilities, this sip paging gateway supports multiple codecs including OPUS 48kHz and MP3 playback, ensuring superior sound quality through connected analog speakers. The front-panel volume controls enable immediate audio level adjustment without software configuration, making it particularly valuable in retail environments, small offices, and restaurants where quick adjustments are frequently needed. The GPIO alarm inputs automatically trigger emergency announcements through connected speaker systems when integrated with security devices.
Perfect for retail stores, hotels, and small to medium businesses, this sip paging gateway seamlessly connects traditional paging equipment to modern VoIP systems. The PoE capability reduces installation complexity while the compact metal enclosure ensures durability. By bridging analog speakers, microphones, and amplifiers with IP networks, the NS-T20 provides an cost-effective upgrade path to sophisticated SIP Paging System capabilities without replacing existing audio infrastructure.
