T-Mobile US call forwarding codes

All calls | **21*[number]# | ##21# |

Forward missed calls to an AI receptionist
The same codes work with Sysevo. Get a number for an AI voice agent, then use the “when you don’t answer” code so the agent picks up the calls you miss: it answers, books, takes the details and logs everything in your CRM. Your customers keep dialling the number they already know, and nothing is ported or switched off. See phone numbers and AI voice agents.
