IP Intercom HelpDesk Software

Easy Set-up and Configuration with IP Intercom HelpDesk Software

The free IP Intercom HelpDesk software makes it easy to set up, manage, and monitor the IP intercom system. The software lets you quickly configure system options and does not require any programming knowledge. The software runs on up to four Windows-based PCs and provides the ability to:
  • Transmit, receive, and forward calls or pages
  • Record, log, and archive audio events
  • Forward prerecorded voice announcements or chimes to a group of rooms

Easy Set-up and Configuration

The free IP Intercom HelpDesk software makes it easy to set up, manage, and monitor an IP Intercom system. This software lets you quickly configure system options and does not require any programming knowledge.

Paging Capability

The software also includes a convenient paging capability, allowing the help desk operator to page a single room or a group of rooms simultaneously. A line level audio output is provided for mixing into a local sound system in each room.

Activity Call Logging

Using the intuitive IP Intercom HelpDesk software, intercom calls and pages can be logged, and date/time-stamped on the help desk computer. Activity logs can be accessed and archived for record keeping and tracking purposes.


The IP Intercom System enhances security operations by allowing audio monitoring for each room. Help desk operators or other authorized personnel can use the IP Intercom's audio monitoring capability to listen to the activity in the room, especially after hours, helping them determine if security personnel should be dispatched to investigate. Audio monitoring can be disabled, if necessary, to comply with local regulations and policies.

The Extron IP Intercom System is ideal for campus-wide AV systems that require internal communications, help desk support, and security/status monitoring.
