Algo 2507 Ring Detector allows IP Notification without a SIP Registration. The Algo 2507 Ring Detector is designed to enable loud ringing, notification, and visual alerting directly from a compatible IP phone without a SIP registration. The 2507 can detect when the phone is ringing and activate an Algo device with a smart relay input, such as an Algo SIP speaker or Algo SIP strobe light (.e. 8128G2, 8138, 8180, 8186, 8188, 8189, 8198, 8196, 8301). See documentation for compatible Poly and Yealink phones. Once the Algo 2507 Ring Detector has activated the Algo IP device, the IP device if desired can be configured to activate other Algo devices via an available relay or it may simultaneously multicast to other Algo IP endpoints on the network creating a scalable notification system directly from a single IP phone. The advantage of the Algo 2507 is that no additional seat registration on the cloud / hosted IP telephone system is required for the ring detector thereby avoiding an additional provider charge and/or recurring monthly cost.
