How to Forward Calls from Nextiva to Ringing.io
Open the Nextiva Voice Admin Dashboard, edit the user, expand Forwarding, and point Call Forward Always (or Selective) at your Ringing.io number.
Nextiva is user-based: forwarding rules attach to each Nextiva user / extension, not directly to a phone number. The Voice Admin Dashboard exposes four call-forwarding options under each user: Call Forward Always, Call Forward When Busy, Call Forward When Unanswered, and Call Forward Selective. Selective supports time-based schedules — create the schedule under My Account > Schedules first, then reference it inside the rule.
Forward every call to Ringing.io (Call Forward Always)
Turn on Call Forward Always on your Nextiva user so every inbound call lands at your Ringing.io AI receptionist.

Call the user's Nextiva number from another phone. It should bypass Nextiva devices and ring through to Ringing.io.
How to undo: Return to Users > Manage Users > the user > pencil icon > Forwarding > Call Forward Always, toggle OFF, and Save. You can also dial *73 from the user's Nextiva line to deactivate Call Forward Always quickly.
Note: Some Nextiva plans gate external forwarding behind a feature pack. If you cannot save an external number, contact your Nextiva account admin to verify Call Forwarding is enabled for your seat.
After-hours only — Ringing.io covers nights, weekends, holidays
Use Call Forward Selective with a schedule so calls forward to Ringing.io outside business hours and ring your team during the day.
- 1
Create the schedule first
In the Voice Admin Dashboard, hover the username in the top-right and click My Account > Schedules > Create Schedule. Name it (e.g. "Business Hours"), choose Time as the type, and add each day with its open hours. Save.
- 2
Open the user > Forwarding > Call Forward Selective
Users > Manage Users > the user > pencil icon. Scroll to Forwarding and click Call Forward Selective.
- 3
Set the default forward number to Ringing.io
In the Default Forward Number field, enter your 10-digit Ringing.io number. This is where calls go when the selective criteria match.
- 4
Add a rule with the "after-hours" criterion
Click Add Rule. Name it (e.g. "After-hours to Ringing.io"). Choose the time schedule you created — but invert: tick "Forward to specified number" when calls come in OUTSIDE the Business Hours schedule. (If your Nextiva tier only matches inside-schedule, build the schedule for off-hours instead.) Save the rule.
- 5
Toggle Call Forward Selective ON
Back on the Call Forward Selective page, set the master toggle to ON and Save.
- 6
Test
Temporarily edit the schedule so the current time falls in your "after-hours" window. Call the line — it should land at Ringing.io. Restore the real schedule when done.
How to undo: Open Forwarding > Call Forward Selective, toggle OFF (or delete the after-hours rule), and Save. The user will revert to ringing their normal devices 24/7.
Ring your phones first, forward misses to Ringing.io
Use Call Forward When Unanswered (and Call Forward When Busy) so the AI only picks up when you do not.
- 1
Open the user > Forwarding section
Voice Admin Dashboard > Users > Manage Users > the user > pencil icon. Scroll to Forwarding.
- 2
Configure Call Forward When Unanswered
Click Call Forward When Unanswered. Enter your Ringing.io number in the Phone Number field, choose the Number of Rings (typically 4-6 rings ≈ 20-30 seconds), toggle ON, and Save.
- 3
Configure Call Forward When Busy
Click Call Forward When Busy. Enter the same Ringing.io number, toggle ON, and Save. Now incoming calls to a busy line also reach the AI.
- 4
Make sure Call Forward Always is OFF
Confirm Call Forward Always is toggled OFF — otherwise it overrides the conditional rules and the phone will never ring.
- 5
Test
Call your Nextiva number from another phone and do not answer. After the configured ring count, the call should reach Ringing.io.
How to undo: In Forwarding, toggle Call Forward When Unanswered and Call Forward When Busy OFF and Save. Missed calls revert to Nextiva voicemail.
Note: If your Nextiva voicemail "ring duration" is shorter than the forward ring count, voicemail will pick up first. Lower the voicemail timeout (or raise the unanswered ring count) under the user's Voicemail settings so forwarding always wins.

Frequently asked questions
Where exactly is call forwarding in Nextiva?
In the Nextiva Voice Admin Dashboard (NextOS > Voice). Hover over Users > Manage Users, click the pencil icon next to a user, and expand the Forwarding section. Four options live there: Call Forward Always, When Busy, When Unanswered, and Selective.
Does Nextiva support time-of-day schedules?
Yes, via Call Forward Selective. Create a Time schedule first under My Account > Schedules > Create Schedule, then reference it inside a Call Forward Selective rule. Nextiva also supports Holiday schedules so you can route holidays separately.
Can I use star codes instead of the portal?
Yes. From a Nextiva user's phone, dial *72 + the forwarding number to enable Call Forward Always, and *73 to deactivate. Star codes only set Call Forward Always — for schedules or conditional rules you must use the admin portal.
Are forwarding rules per-user or per-line?
Per-user. Each Nextiva user / extension has its own forwarding configuration. To forward your main company number, edit the user assigned to the main number, or configure the Auto Attendant / Hunt Group that owns the main number.
Why is my forwarded call going to Nextiva voicemail instead of Ringing.io?
Usually the voicemail timeout is shorter than the Call Forward When Unanswered ring count. Lower the voicemail "no answer" delay in the user's Voicemail settings, or raise the unanswered ring count so forwarding kicks in first. Also confirm Call Forward Always is OFF if you are testing the unanswered path.
Can a regular user change their own forwarding without an admin?
Yes — users with a NextOS login can sign in to their own portal and edit the Forwarding section for their seat. Account-wide changes (Auto Attendants, schedules used by many users) still require an admin.
Will SMS to my Nextiva number be forwarded?
No. Nextiva call forwarding redirects voice calls only. Text messaging is handled by the separate Nextiva Business Texting feature and continues to deliver to the original Nextiva inbox.
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 Nextiva.
