Which kind of forwarding to use
Always
Every call goes to FrontDesk Talk and your phone never rings. Use it when you want the AI to answer everything, or at night and on weekends.
No answer
Your phone rings first. If you don’t pick up, the call moves to FrontDesk Talk. This is the setup most owners start with.
Busy
If you’re already on a call or you decline one, the caller goes to FrontDesk Talk instead of voicemail.
Unreachable
If your phone is off, out of battery, or has no signal, calls still get answered.
Our advice for T-Mobile: Start with no answer, plus busy and unreachable as backups. Your phone rings first, and FrontDesk Talk answers anything you miss.
The T-Mobile codes
| Forwarding | Turn on | Turn off |
|---|---|---|
| Always | **21*Talk number# | ##21# |
| No answer | **61*Talk number# | ##61# |
| Busy | **67*Talk number# | ##67# |
| Unreachable | **62*Talk number# | ##62# |
| Everything off | Not needed | ##002# |
Replace Talk number with your 10-digit FrontDesk Talk number, then press Call. Codes can vary by plan. If one doesn’t work, call your carrier.
Step by step
Find your FrontDesk Talk number
It’s the number we give you during setup. Use all 10 digits, no spaces.
Open your phone’s keypad
Use the regular phone app on your T-Mobile line.
Dial the code for no answer
Dial the code below and press Call. A message on screen confirms it.
**61*Talk number#Add busy and unreachable
Repeat with these two codes so calls still get answered when you’re busy or out of signal.
**67*Talk number# and **62*Talk number#
Good to know
- To change how long your phone rings first, add a ring time in seconds: **61*[Talk number]**20# waits about 20 seconds.
- Some business and prepaid lines handle forwarding differently. If a code fails, dial 611 from your T-Mobile phone.
Test it
- Call your business number from a different phone.
- If you set up always, you should hear your FrontDesk Talk greeting right away. If you set up no answer, let it ring without picking up.
- Check your text messages. A Talk Note, the summary of the call, should arrive a moment after you hang up.
Turn it off
Dial ##002# and press Call. That clears every kind of forwarding.
Before you cancel FrontDesk Talk, turn off forwarding so calls go back to your phone.
Questions
The code says “connection problem or invalid MMI code.”
Check the stars and the pound sign. If it still fails, forwarding may need to be turned on for your line. Dial 611 from your phone.
Will my callers know the call was forwarded?
No. They dial your usual number and hear your receptionist. Nothing sounds different on their end.
Does forwarding cost extra?
Most plans include forwarding. Some carriers count forwarded calls against your minutes if your plan isn’t unlimited. Check with your carrier if you’re not sure.
Can I still make calls from my phone?
Yes. Forwarding only changes where incoming calls go. Outgoing calls work the same as before.
Can I switch between always and no answer?
Yes. Turn one off and the other on anytime. Many owners use no answer during the day and always at night.
Would porting my number be better?
Forwarding is quickest. Porting moves your number to us so you can drop the old line. Read the porting guide.
