Due to a growing demand in VoIP Public Address and especially IP based Loud Phone Ringers, we thought a guide detailing available products and most recent data sheets would be helpful for you.

We provide IP enabled SIP endpoints for VoIP Networks. All products integrate with your end users IP-PBX (SIP Server). All products are directly certified & supported by around 37 IP Phone System Manufacturers.

VoIP Loud Ringers & Public Address – On-Site & Hosted Integration

TWO PRODUCTS IN ONE: Each Certified SIP endpoint we provide features 2 x SIP Lines, this allows you to integrate the device to 2 x Phone Extensions on your network. This is especially useful if you want to use the device for Public Address Announcements & Loud Ringing.

If Phone Extension one is called, you can make a live announcement, if phone extension two is called, an audio file can play. Alternatively, just use the Endpoint for either or. Remember: With each device, its not just for use with one phone, from the IP Phone System, you can join many extensions into a hunt group. Therefore, each below device can ring for multiple IP Phones.
