Intercom is a feature that allows you to page an individual phone, or even an entire ring group, by automatically activating their speakerphone—unless the receiving phone is on another call or set to do not disturb. This is convenient for reaching people who are frequently near their phone, but not right next to their phone—like a warehouse worker or a teacher.
1. Dial * + ext from your phone.
- This feature is automatically enabled when a line is created. If it has been disabled, contact your system admin.
2. Say what you gotta say (remember, everyone can hear you).
3. Hang up.
Tip: Ring groups are automatically compatible with the intercom feature. Dialing * + ring group extension will cause members of that ring group to auto-answer your call on speaker. To avoid confusion (and feedback), members of the target ring group will only RECEIVE audio and will not SEND audio to the call.
Tip: This feature is different from multicast paging, but can be used as a simple workaround if multicast paging is not an option (e.g. equipment limitations or different locations across multiple networks).
With ring groups, what happens when...
Q: One member of the ring group is on a call?
- On a Linksys/Cisco SPA, it will interrupt the call.
- On a Snom and Polycom, it won’t interrupt the call, it will just ring in the background.
- The call proceeds as normal and the lines will immediately pick up. External numbers will begin ringing and will hear the intercom as soon as the call is answered.
- The call proceeds as normal, but the member on DND is ignored.
- The disabled setting is overruled, and the line will auto-answer the call.
