Two ways to get your Optimum Business number to your agent. Forwarding keeps Optimum Business as your phone company and sends calls over. Moving the number (porting) makes Answering Agent your phone company for that number.
Forwarding codes are confirmed on two official Optimum Business PDF guides (high confidence, including busy/no-answer codes found in the West Guide). Optimum publishes no official business landline port-out how-to; porting fields beyond account-number placement are left null rather than borrowing Optimum Mobile’s documented process, which is a different product with a different Transfer PIN system.

​
Forward calls

1

Sign in to the User Portal (optional)

In the My Services area, select Call Forwarding and enter the number forwarded from and the number forwarded to.
2

Or use the phone keypad

Lift the receiver and listen for a dial tone.
3

Dial *72

This activates Call Forwarding Always.
4

Enter the destination number

Wait for the confirmation tone, then dial the number to which calls should be forwarded.
5

Deactivate when done

Dial *73 from the handset to turn off Call Forwarding Always.
6

Call your business number from another phone

Answering Agent listens for the call. When your agent picks up, the phone numbers step in your dashboard turns green.

​
Good to know

  • Deactivate Call Forwarding Busy with *91 and Call Forwarding No Answer with *93.
  • Optimum Business also documents Call Forwarding Not Reachable (*94, number of rings configurable) for when the line can’t register.

​
Move your number

Start the move from Dashboard, then Phone numbers, then Add a number, and choose Move my number. Upload your latest bill and we read the details for you. Have these ready:
Do not cancel your service with Optimum Business until the move is complete. A cancelled number can be lost.

​
Watch out for

  • No official Optimum Business page describing a customer-facing landline port-out procedure was found; Optimum directs business customers to call support (888-276-5255) rather than publishing self-serve steps.
