Talk-A-Phone has introduced its Native VoIP 500 Series Emergency Phones, which can be connected directly into existing routers and LAN infrastructure. The new unit is a direct physical replacement of a Talk-A-Phone 400 Series analog phone. Many custom faceplate sizes are available, allowing other manufacturer's analog phones to be easily upgraded. The phone's built-in Layer 2 switch enables other IP devices to be connected directly into phone, further enhancing IP integration options. Additionally, the phones can be paged at high volume with the supplier's WEBS Contact mass notification software, enabling emergency personnel to issue targeted alerts to any segment of a facility.
