Description
Connect your SIP phone system to existing 25V, 70V, or 100V speaker lines with the VIP-851-70/100, a 20-watt multi-voltage IP SIP amplifier gateway that drives up to 40 Valcom amplified speakers with PoE+ power and automatic AUX music muting.
The Telecom Spot Expert Review
The multi-voltage VIP-851-70/100 is the right gateway when your facility has 70V or 100V speaker runs — it handles all three common distributed audio voltages (25V, 70V, and 100V) from one product. Three audio outputs let you split the downstream speaker load across independent runs. The base version has no InformaCast or Syn-Apps licensing, making it the straightforward SIP-only choice for facilities that do not use a mass notification platform.
