Native VoIP 500 Series Emergency Phones from Talk-A-Phone Co. of Niles, Illinois, can be connected directly into existing routers and LAN infrastructure. They directly replace the company’s 400 Series analog phones. Many custom faceplate sizes are available, allowing analog phones from other manufacturers to be easily replaced. A built-in Layer 2 switch allows other IP devices to be connected directly into the phones, further enhancing IP integration. The phones can be paged at high volume with the company’s WEBS Contact mass notification software, allowing emergency personnel to issue targeted alerts to any segment of a facility. The software automatically tests and verifies connectivity and sends e-mail alerts when it fails.
