Valcom VIP-851-25 Sip Gateway Power Amplifier 20W

Product Description

The VALCOM VIP-851-25 is a SIP-based gateway and power amplifier designed for voice-over-IP paging and intercom distribution systems. Rated at 20 watts output with a 25-volt line configuration, it bridges VoIP network infrastructure to analog 25-volt paging speaker systems. Installation is typically performed by low-voltage communications technicians or commercial electricians integrating IP-based paging into facilities. The unit ships as a single piece (each) and is categorized as a power amplifier within the Valcom product line.

The VIP-851-25 is suited for commercial and institutional paging applications where an existing 25-volt speaker network needs to be driven from a SIP-compatible IP communications platform. Typical installations include office buildings, schools, warehouses, and healthcare facilities upgrading from analog paging to VoIP-based systems. The 20-watt output capacity supports distributed speaker loads common in these environments.
