CyberGate Call Groups for Sequential and Parallel Calling

Written by Frank Kuipers | Mar 31, 2026 7:10:20 AM

Setup Intercom Call Destinations once — and never touch them again.

Picture this: a Teams user assigned to answer intercom calls changes role or leaves the company. You’ve got 25 intercoms deployed, sourced from 3 different manufacturers. Now you have to update the call Destination on every single device. Three intercom brands means three UIs, three different ways of doing the same task. And the worst part: next month, when someone else changes position, the party starts all over again.

CyberGate Call Groups solves this problem.

One Destination. All the Flexibility.

With CyberGate Call Groups, you configure a single call Destination in your Intercom, just once.

This Destination points to CyberGate, and from there CyberGate takes over: who gets called, in what order, and what happens if nobody answers.

What if someone leaves, changes role, or a new Teams member joins? You update it in CyberGate. One change. One portal, for all 28 supported intercom brands, instantly updated. No logging into intercom device UIs. No vendorspecific menus. No chance of missing one.

CyberGate Call Groups - Three routing models

  • Sequential Calling
  • Parallel Calling
  • Sequential and Parallel Calling combined

Each model is best explained with an example. In each diagram below, note that the intercom call Destination (‘Entrance_AMS’) is configured once and never changes.

Sequential Calling

Call multiple Teams users one after another. If the first person is busy or doesn’t answer, CyberGate moves on to the next in line. And the next, until someone picks up.

 

Parallel Calling (Multi Ring)

Call up to 15 Teams users simultaneously. The first person in the Ring Group who picks up is connected to the visitor.

 

Combined: Sequential and Parallel Calling

Chain multiple Call Groups in sequence, where each group can be a single user or a Multi Ring group of up to 15 users. First, try the reception team (parallel). If no one answers, try the supervisors team (parallel). If still nobody answers, escalate to security team lead (single).

 

Why this matters for IT ?

  • Every intercom vendor has its own UI, menu structure, and terminology. So if you’ve deployed intercom devices from three different manufacturers, your IT team has to learn and remember three UIs and three different configuration methods.
  • Updating call routing across dozens of intercom devices is a headache. Logging into each device one by one just to change a call Destination is tedious, errorprone, and a drain on your IT teams time.

How to Set Up Call Groups

Step 1: Create your Call Group in CyberGate

  • Login to the CyberGate Management Portal
  • Navigate to menu Basic Call Group
  • Create one or more Multi Ring Groups for Parallel Calling.
  • Finally, create a Call Group of type Sequential and chain ring groups and / or team supers.
  • Set the calling Destination in your intercom to the Call Group address (e.g. Entrance_AMS@cybergate.cybertwice.com).

 

Step 2: Point your intercom to the Call Group

Ringing Duration - Settings You Should Know

CyberGate Ringing Duration (5-30 seconds)

  • Defines after how many seconds CyberGate will move on calling the next Destination in a sequential Call Group, if the previous Destination is busy, or didn’t answer.
  • Ringing Duration is configurable in the CyberGate Management Portal, per Call Group.
  • Defines how many seconds the IP Intercom will try calling a Destination.
  • This is how long your intercom will wait for a connection before giving up. When using sequential calling, make sure this value covers the total ring time. Example: 3 sequential Destinations at 15 seconds each = set your intercom timeout to at least 45 seconds.
  • Configure once in: IP Video Intercom

Intercom Maximum Ringing Time

Pro tip: Always calculate your intercom timeout as: number of sequential steps x CyberGate ringing duration. If you add more steps later, remember to increase the intercom timeout accordingly.
