Short Version
Teams on mobile is getting a Message option on the incoming call screen. Tap it to decline the call and send the caller a quick reply at the same time, either a predefined message or a custom one typed in the Teams chat. It works for Teams-to-Teams calls only, not phone calls. Due early to mid-December 2026.
Details
When a Teams call comes in on your Android or iOS device, you will see a new Message (1) option alongside the usual accept and decline buttons. It gives you a faster way to let the caller know where you stand, without answering the call or opening the chat separately afterwards.
- Custom reply: select Custom (2) to decline the call and open the Teams chat with that person, so you can type your own message.
- Predefined replies: choose from ready-made responses such as “Can I call you later?”, “I’m on my way.” or “Sorry, I can’t talk right now.” (3). Tapping one declines the call and sends the message to the caller in Teams chat straight away.
- Carry on in chat: the reply appears in your Teams chat with the caller (4), so the conversation can continue there once the call has been declined.
- Teams-to-Teams calls only: the option needs a Teams chat to send the message to, so it does not apply to phone (PSTN) calls, anonymous calls or calls from other platforms connected to Teams (interoperability calls).
- Nothing else changes: the existing accept and decline options stay as they are.
The feature arrives automatically as it rolls out; there is nothing to switch on.
