How to Forward Calls from OpenPhone to Ringing.io
OpenPhone (rebranded to Quo in 2025) uses a visual call-flow builder — drop a Forward block onto your call flow and point it at Ringing.io. Schedules, ring groups, and after-hours routing are all built in.
OpenPhone became Quo in 2025, so the documentation now lives at support.quo.com (links may show the Quo brand). Your existing OpenPhone numbers and app continue to work. Every scenario below is built using the visual call-flow editor at Settings > Phone numbers > [your number] > Edit call flow.
Forward every call to Ringing.io
Replace the default call flow with a single Forward step that sends every inbound call straight to your Ringing.io number.
- 1
Sign in to OpenPhone
Open my.openphone.com (or the desktop / mobile app) and sign in to your workspace.
- 2
Open Settings > Phone numbers
Click Settings in the top-left menu, then choose Phone numbers under Workspace.
- 3
Select your phone number
Click the phone number you want to forward.
- 4
Open the call-flow editor
Scroll to the call-flow section and click Edit call flow to open the visual builder.
- 5
Remove the default Ring users block
Delete the existing Ring users (or other) block under the Incoming call trigger so you have a blank canvas under the trigger.
- 6
Add a Forward block pointing at Ringing.io
Drag the Forward block onto the canvas, connect it under the Incoming call trigger, and enter your full 10-digit Ringing.io number as the destination.
- 7
Save and test
Save the call flow. Call your OpenPhone number from another phone — it should ring through to Ringing.io and the AI receptionist should pick up.
How to undo: Open the call flow again, delete the Forward block, and put your Ring users block back under the Incoming call trigger. Save.
Note: OpenPhone also exposes a "Forward all calls" toggle in number settings as a quick override — useful when you want to redirect everything to Ringing.io temporarily without modifying your default call flow.
After-hours only — Ringing.io covers nights and weekends
Use the Business hours block so your team rings during business hours and Ringing.io picks up everything after hours.
- 1
Open Settings > Phone numbers and select your number
In OpenPhone, go to Settings > Phone numbers and click the number you want to configure.
- 2
Enable Business hours
Scroll to Business hours, toggle "Enable business hours" on, choose your time zone, and set your weekly schedule (Every day, Weekdays, or Custom by day).
- 3
Open the call-flow editor
Click Edit call flow to open the visual builder.
- 4
Add the Business hours block under Incoming call
Drag the Business hours block onto the canvas and connect it under the Incoming call trigger. This creates two branches: During hours and After hours.
- 5
Set During hours to Ring users
On the During hours branch, add a Ring users block and select your team members (or yourself). Set the ring strategy and duration.
- 6
Set After hours to Forward to Ringing.io
On the After hours branch, add a Forward block and enter your Ringing.io number.
- 7
Save and test
Save the call flow. Test by calling during business hours (should ring your team) and outside business hours (should reach Ringing.io). You can temporarily narrow the business-hours window to force an after-hours call for testing.
How to undo: Open the call flow, delete the Forward block from the After hours branch, and either remove the Business hours block or set its after-hours path to Voicemail. Save.
Note: OpenPhone supports one consecutive time period per day — you cannot configure split shifts like 9am-noon and 2pm-5pm on the same day. If you need split shifts, configure them inside Ringing.io instead and forward all calls there.
Ring your team first, send misses to Ringing.io
Ring your team for a set duration; if nobody answers, the call falls through to Ringing.io instead of voicemail.
- 1
Open the call flow for your phone number
Settings > Phone numbers > select your number > Edit call flow.
- 2
Configure a Ring users block as step 1
Under the Incoming call trigger, add a Ring users block. Select your team members, choose a ring strategy (All at once, Random, or Custom on Business/Scale plans), and set a total ring duration (15-30 seconds is typical).
- 3
Add a Forward block as the next step
Below the Ring users block, drag a Forward block onto the canvas and connect it. This is the fallback if nobody in the Ring users block answers within the ring duration.
- 4
Enter your Ringing.io number
In the Forward block, enter your full 10-digit Ringing.io number.
- 5
Save and test
Save the call flow. Call your OpenPhone number and let it ring through without anyone answering — after the ring timeout, the call should be forwarded to Ringing.io rather than dropping to voicemail.
How to undo: Open the call flow and either delete the trailing Forward block or replace it with a Voicemail block. Save.
Note: Make sure the Forward block is placed after Ring users in the flow. If you place it before, OpenPhone will forward immediately and your team will never ring. The visual builder shows the call path from top to bottom.

Frequently asked questions
Did OpenPhone rebrand to Quo?
Yes — OpenPhone rebranded to Quo in 2025. Your existing OpenPhone account, numbers, and apps continue to work. Support documentation now lives at support.quo.com and the marketing site is openphone.com / quo.com. The product, UI flows, and pricing tiers remain the same.
Where do I set up call forwarding in OpenPhone?
In the OpenPhone app at Settings > Phone numbers > select your number > Edit call flow. The visual call-flow builder lets you drag a Forward block onto the canvas and point it at any external number — your Ringing.io number, for example.
Does OpenPhone support business-hours / time-of-day schedules?
Yes. Each phone number has independent business-hours settings. Drag a Business hours block into the call flow and the call splits into During hours and After hours branches — each can have its own destination, including a Forward block to Ringing.io.
Can I forward only when nobody on my team answers?
Yes. Place a Ring users block first in the call flow, then a Forward block below it pointing at Ringing.io. OpenPhone rings your team for the configured ring duration; if nobody picks up, the call falls through to the Forward block and reaches Ringing.io.
What is the "Forward all calls" toggle in number settings?
It is a quick override that immediately forwards every call to a single number, bypassing your normal call flow. Useful for vacations, emergencies, or any time you want to redirect everything to Ringing.io without editing your call flow. Toggle it off to return to your default flow.
Does OpenPhone support split shifts (e.g. 9-12 and 2-5)?
Not natively — OpenPhone's Business hours block supports one consecutive time period per day. If you need split shifts, configure your full schedule inside Ringing.io and have OpenPhone forward all calls to Ringing.io 24/7.
Will SMS to my OpenPhone number be forwarded to Ringing.io?
No. The Forward block in call flows handles voice calls only. SMS and MMS continue to land in the OpenPhone inbox. If you need messaging automation, configure OpenPhone's message handling separately.
Don't have a Ringing.io number yet?
Get one in five minutes, set up your AI receptionist, then come back to this page to forward OpenPhone.
