Service codes
About service codes
Service codes are GSM codes you dial on a traditional mobile phone that has a keypad instead of a touch screen. As such, service codes allow you to use certain One Net Business features with no need for the One Net app or a desk phone.
You can use service codes to:
- Put calls on hold
- Set up conference calls
- Transfer calls
Using service codes
To use any of the service codes, you need to put a call on hold first.
To put a call on hold
- Dial 2 and select the call button.
To resume a held call
- Dial 1 and select the call button.
To start a conference call
- Dial 2 and select the call button to put a call on hold.
- Dial the number of the person you want to add as a second participant.

You can add up to three participants altogether.
