Algo 8180 IP Loud Ringer, SIP Speaker, & Voice Paging Device

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.

Features / Benefits

  • High efficiency for maximum sound level
  • Wideband audio and output level outperforms traditional telephone loud ringers
  • SoundSure™ ambient noise compensation
  • Includes several ring tones including chime, gong, warble, and dogs
  • Network managed SIP endpoint
  • Dual purpose loud ringing and/or voice paging
  • Significantly louder (eight to twenty times) than typical telephones

The advanced features of the 8180 include SoundSure technology which automatically adjusts loud ring volume to compensate for background ambient noise. For environments with variable noise levels (restaurants, workshops, classrooms etc) the 8180 can step up the volume when necessary to be heard and provide a more comfortable level during quiet periods. Outputs for external speaker, slave amplifier, or visual alerter plus multicasting capability enable many more options to enhance notification and alert capabilities. Configuration is possible using the feature buttons or web interface.
