The simplest configuration you can make in Romulus is this: when someone calls your number, your phone rings. This article walks you through it step by step.
Before You Start
Make sure you have:
At least one active phone number on Romulus
The Romulus app installed on your device (desktop or mobile)
At least one user created in the Team section
💡 If you are not yet familiar with the rules system, we recommend reading How Inbound Rules Work first.
Scenario 1 — Calls ring only on my phone
This is the simplest case: all incoming calls ring directly on your phone.
From the side menu, click Phone Numbers.
Click on the number you want to configure.
Go to the Inbound Rules tab.
Click + Create rule. The flow editor opens.
You will see the fixed starting block: Inbound call – When a call comes in. This is where you build your flow.
Click + Select step to add the first block.
Select Call user from the list.
Choose your name from the list of users.
Click Save.
Assign a schedule to the rule — to receive calls at all times, select every day (Mon–Sun) with the time range 00:00–23:59.
From this point on, every incoming call will ring your Romulus app.
Scenario 2 — Calls ring for multiple people at the same time
If you want incoming calls to reach the whole team simultaneously, use the Call group block instead of Call user.
Follow steps 1–6 from Scenario 1.
Select Ring group from the block list.
Choose a group of type Standard from the list.
Click Save and assign a schedule to the rule.
With a Standard group, all users in the group ring at the same time. Whoever answers first takes the call.
💡 If you have not yet created a group, go to Team → Groups and create one before coming back here.
Scenario 3 — What happens if nobody answers?
You can handle the case where no one picks up by adding a second block after Call user or Call group. The system will automatically move to the second block if the call goes unanswered within the configured time.
Examples of what you can do after a missed call:
Voicemail — the call goes to voicemail and the caller can leave a message
Call another user — the call is passed to a second team member
Play audio — the caller hears an informational message (e.g. "We are temporarily unavailable, please call us back shortly")
To add a second block, click + Select step below the first block in the flow editor and choose the desired action.
Frequently Asked Questions
Will I receive calls on both desktop and mobile?
Yes. If you have the app installed on multiple devices with the same account, the call will ring on all of them at the same time.
Can I limit the hours when I receive calls?
Yes. When you assign a schedule to the rule, you can specify days and time ranges. For example, you can create a rule that is active only Monday to Friday from 9:00 AM to 6:00 PM. To manage what happens outside office hours, see (coming soon: How to Handle Calls Outside Business Hours).
How do I know if the rule is active?
A rule is active when it has been assigned a schedule and its status is active. You can check this in the Inbound Rules tab of the number.
