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.

Questions

What is the code to forward all calls?

On most mobile networks it is **21*[number]# to forward every call, **61*[number]# when you don’t answer and **67*[number]# when you’re busy. Dial ##21#, ##61# or ##67# to turn each off, or ##002# to clear them all. Canadian networks use a single star (*21*[number]#), and Verizon, US Cellular and Boost Mobile use *72, *71 and *90.

How do I check whether call forwarding is on?

On most GSM networks, dial *#21# and press call. Your phone shows whether forwarding of all calls is active and where calls are going.

Does call forwarding cost anything?

Setting it up is free on most networks, but forwarded calls can be charged as an outgoing call from your line, depending on your plan. Check your network’s tariff, especially when forwarding abroad.
