If your team has more than one person, you can configure Romulus to automatically distribute incoming calls among them. The tool for this is the Call group block, which works in three different ways depending on how you want to manage calls.
💡 Before configuring the inbound rule, make sure you have already created the group in Team → Groups. See How to Add and Manage Users in Your Phone System for details.
For the general context on rules, read How Inbound Rules Work. For a description of each block, see The Available Blocks in Inbound Rules.
The three group types — which one to choose
Type | How it works | Best for |
Standard | Everyone rings at the same time — first available answers | Small teams, fast response |
Cascade | Ring in sequence: first person first, then second, etc. | Prioritising a lead contact |
Queue | Calls wait in line and are assigned to the first free user | High call volumes, no missed calls |
How to add the Call group block to a rule
From the side menu, click Phone Numbers.
Click on the number you want to configure.
Go to the Inbound Rules tab.
Create a new rule or edit an existing one.
In the flow editor, click + Select step.
Select Call group from the list.
Choose the group you want to ring from the dropdown menu.
Click Save changes.
The call behaviour will depend on the type of group you selected.
Scenario 1 — Everyone rings at once (Standard group)
All members of the group receive the call at the same time. Whoever answers first takes the call; the others stop ringing.
Typical example: a three-person sales team — whoever is free answers the customer immediately, with no waiting.
Scenario 2 — Ring in order (Cascade group)
The call rings the first member of the group. If they don't answer within the configured time, it moves to the second, then the third, and so on.
Typical example: the sales manager is the first to receive the call. Only if they are unavailable does the call move on to other team members.
Scenario 3 — Call queue (Queue group)
Calls are placed on hold and distributed to the first user in the group who becomes available. Customers wait in queue in order of arrival — no call is missed, even during peak times.
Typical example: a customer support service with multiple agents. During busy periods, customers wait in a queue instead of getting a busy signal.
What happens if nobody answers
If no member of the group answers within the configured time, you can add a follow-up block in the flow to handle the call. The most common options are:
Voicemail — the caller leaves a message
Play audio — the caller hears an informational message
Call transfer — the call is forwarded to an external number
To add a follow-up block, click + Select step below the Call group block in the flow editor.
Frequently Asked Questions
Can I use more than one group in the same rule?
Yes. You can add multiple Call group blocks in sequence within the same rule — for example, the sales group rings first, and if no one answers, the support group rings next.
Can I change the group type at any time?
Yes. Go to Team → Groups, select the group, and change the type. The change applies immediately to all rules using that group.
How many people can I add to a group?
There is no limit to the number of users you can add to a group.
Can a user be part of multiple groups?
Yes. The same user can be added to multiple different groups.
