Algo 8180 SIP Audio Alerter for Loud Ring and Voice Paging

The 8180 SIP Audio Alerter is a SIP compliant PoE network audio device for loud ring and voice paging applications using dual endpoints. When registered with a SIP server, one endpoint will play an audio file from internal memory upon ring detection. The second endpoint will auto-answer for voice paging, complete with two-way talk-back.

Equipped with a high efficiency integrated amplifier and tuned high quality loud speaker, the 8180 is typically eight times louder than a telephone speaker. If the optional 1185 Horn Speaker is used, then the 8180 can be twenty times louder. Several audio files are pre-loaded into the 8180 internal memory for ring sounds but users may also record or upload custom audio files, music, sound effects, or voice announcements.


The advanced features of the 8180 include SoundSure™ technology which automatically adjusts loud ring and paging volume to compensate for background ambient noise. Ideal for variable noise environments (restaurants, workshops, classrooms, etc.), SoundSure™ ensures that ringing or paging is always heard but not unnecessarily loud.

Outputs for external speaker, slave amplifier, or visual alerter plus multi-casting capability enable many more options to enhance notification and alert capabilities. Configuration is possible using the feature buttons or web interface.
