How to Forward Calls from Cox Business to Ringing.io
Cox Business VoiceManager and IP Centrex use the standard *72 / *73 star codes plus a full web portal at MyAccount. Use star codes for quick on/off, MyAccount for schedules and selective rules.
Cox Business Voice is line-based: forwarding rules attach to a phone number. Two main service tiers — VoiceManager (SMB) and IP Centrex (cloud PBX) — share the same feature access codes and a similar MyAccount portal. Selective Call Forwarding with time-of-day rules is available on most VoiceManager and IP Centrex packages but the exact UI depends on your plan. The Voice Portal phone number (a per-region call-in number) is a third way to manage forwarding from any phone using your passcode.
Forward every call to Ringing.io (Call Forward Always)
Activate Call Forward Always via *72 or the Cox Business MyAccount portal so all calls on this line reach Ringing.io.
- 1
Option A — from the phone, dial *72
Pick up the Cox Business handset, listen for dial tone, and dial *72. After the second dial tone, dial your 10-digit Ringing.io number. Listen for the confirmation announcement and hang up.
*72 + 10-digit Ringing.io number - 2
Option B — Cox Business MyAccount portal (recommended)
Sign in at myaccount-business.cox.com. Click Voice Tools (or Manage Services > Voice), then select the phone number you want to forward.
- 3
Open Call Forwarding settings
On the line's settings page, expand Call Forwarding. Click Call Forwarding Always.
- 4
Enter your Ringing.io number and turn it on
Enter your 10-digit Ringing.io number in the "Forward calls to" field, set the toggle to ON, and click Save.
- 5
Test
Call your Cox Business number from another phone — it should ring through to Ringing.io with no internal ring on your Cox phone.
How to undo: Dial *73 from the Cox Business line to deactivate Call Forward Always. Or open MyAccount > Voice Tools > the line > Call Forwarding Always and toggle OFF.
Note: On rotary phones (yes, still some out there) dial 1172 for *72 and 1173 for *73. The portal works for everyone regardless of phone type.
After-hours only — Selective Call Forwarding with a schedule
Use Cox Business Selective Call Forwarding with a time schedule so calls forward to Ringing.io only outside business hours.
- 1
Sign in to MyAccount and open the line
myaccount-business.cox.com > Voice Tools > select the phone number > Call Forwarding section.
- 2
Open Selective Call Forwarding (or Call Forwarding Selective)
Expand Selective Call Forwarding. Set the "Default forward to" field to your 10-digit Ringing.io number — this is where calls go when a rule matches.
- 3
Create a Schedule for after-hours
Open Schedules (typically under Voice Tools > Schedules) and create a Time Schedule named "After Hours" with the days and time ranges you want covered (nights, weekends, lunch, etc.). Save.
- 4
Add a Selective Call Forwarding rule
Back on Selective Call Forwarding, click Add Rule. Name it "After Hours to Ringing.io". Choose the After Hours schedule you just created. Leave the caller criteria as "Any" so all callers match during that window. Save the rule and toggle the master Selective Call Forwarding switch ON.
- 5
Test
Temporarily edit the schedule so the current time falls inside "After Hours" and place a test call — it should forward to Ringing.io. Restore the real schedule when confirmed.
How to undo: In Voice Tools > the line > Selective Call Forwarding, either toggle the master switch OFF, or delete the After Hours rule. Save.
Note: Selective Call Forwarding availability depends on your VoiceManager / IP Centrex package. If you do not see it in MyAccount under your line, contact Cox Business to enable the Selective Call Forwarding feature on your seat.
Forward only when busy or no answer
Use Call Forwarding Busy and Call Forwarding No Answer (star codes or portal) so the Cox phone rings first and Ringing.io catches what you miss.
- 1
Enable Call Forwarding Busy
From the Cox line dial *90 + your 10-digit Ringing.io number. Listen for the confirmation tone. (Disable later with *91.)
*90 + 10-digit Ringing.io number - 2
Enable Call Forwarding No Answer
Dial *92 + your 10-digit Ringing.io number. Listen for the confirmation tone. (Disable later with *93.)
*92 + 10-digit Ringing.io number - 3
Or use the MyAccount portal
MyAccount > Voice Tools > the line > Call Forwarding > Call Forwarding Busy / No Answer. Enter your Ringing.io number, set the no-answer ring count (4-6 rings is typical), and toggle ON. Save.
- 4
Confirm voicemail does not intercept
If Cox voicemail picks up before the forward fires, raise the voicemail no-answer ring count (or shorten the Call Forwarding No Answer ring count) in MyAccount so the Ringing.io forward wins.
- 5
Test
Call your Cox Business number and let it ring without answering — Ringing.io should pick up after the configured rings. Test again while on another call to verify busy.
How to undo: Dial *91 to disable Call Forwarding Busy and *93 to disable Call Forwarding No Answer. Or toggle each rule off in MyAccount.
Note: Some features may be restricted by your Cox Business VoiceManager administrator. If a star code returns an error, ask your account admin to enable that forwarding type on your line.

Frequently asked questions
What are the Cox Business call forwarding star codes?
*72 activates Call Forward Always; *73 deactivates it. *90 activates Call Forwarding Busy; *91 deactivates it. *92 activates Call Forwarding No Answer; *93 deactivates it. *63 activates Selective Call Forwarding. On rotary phones use 1172 / 1173 in place of *72 / *73.
Where in MyAccount do I configure forwarding?
Sign in at myaccount-business.cox.com, open Voice Tools (also labeled Manage Services > Voice on some accounts), select your phone number, and expand the Call Forwarding section. From there you can manage Always, Busy, No Answer, and Selective rules.
Does Cox Business support time-of-day schedules?
Yes, on most VoiceManager and IP Centrex packages. Create a Time Schedule under Voice Tools > Schedules, then reference it from a Selective Call Forwarding rule. If your account does not expose Selective Call Forwarding, ask Cox Business to enable that feature on your line.
Can I forward without using the portal?
Yes — three options. From the line itself dial *72 / *90 / *92 with the destination. From any phone dial your region's Voice Portal number, enter your passcode and 10-digit number, and use the menu to change forwarding. Or use the MyAccount portal for full visibility.
Why does *72 not work on my line?
Either the feature is restricted by your VoiceManager administrator, your plan does not include call forwarding, or you are on a rotary line (try 1172 instead). Sign in to MyAccount > Voice Tools and verify Call Forwarding is enabled on the line — if not, contact Cox Business support.
Are there forwarding fees?
Call forwarding is included on most Cox Business Voice plans. Forwarded calls to a domestic US number use your included calling minutes (or are unlimited on most current packages). Your Ringing.io number is a US number, so forwarded calls stay domestic.
Will the original caller's number be visible to Ringing.io?
Yes. Cox Business passes the original calling number through to the forwarding destination via Caller ID, so Ringing.io sees who is calling and can use that for routing, blocklists, or CRM lookup.
