Migrating Teams Calling Bot (EchoBot) from VMSS to Windows Containers / ACI?
Hi everyone, I have built a Microsoft Teams Calling Bot using Application-Hosted Media based on the official C# EchoBot sample: https://github.com/microsoftgraph/microsoft-graph-comms-samples/tree/master/Samples/PublicSamples/EchoBot Currently, our signaling logic is fully serverless and runs efficiently on Azure Functions. However, the actual media processing (using the C# Calling SDK which relies on native Windows media binaries) is deployed on VMSS with Windows Server, just like the repository's default deployment guide suggests. Running these Windows VMs continuously is becoming extremely expensive, and we are looking for a cheaper, modern, or "on-demand" alternative to handle the media pipeline. Since raw audio processing strictly requires these native Windows-based Media binaries, I would like to ask the community: 1. Windows Containers (ACI / AKS): Has anyone successfully run this C# EchoBot/Media SDK inside Windows Containers (such as Azure Container Instances or AKS)? If so, how do you handle the public IP and port-binding requirements for the media sockets (since the platform needs direct public connectivity for UDP/TCP traffic)? 2. On-Demand Provisioning: Are there any known architectures or best practices for spinning up the media processor only when a call starts (e.g., triggering an ACI instance via the Azure Function signaling bot) and tearing it down afterwards to keep costs near zero when idle? 3. Alternative Approaches: If you have solved this high-infrastructure cost problem for a real-time raw audio bot in production, what architecture did you end up using? Any documentation, GitHub references, or architectural advice would be highly appreciated! Thanks!
Can same-tenant meeting bots be routed through lobby approval like external bots?
Hello! As far as I understand, external third-party meeting bots are now detected by Teams and routed to the lobby via RequireApprovalWhenDetected; the organizer must admit them. Same-tenant bots bypass this entirely. Is there currently a way to apply lobby approval to same-tenant bots so it does not appear as a participant until explicitly let into the room? If not, is this on the roadmap? Could for example be a per-app flag on the Entra app registration or a Graph API parameter on the join call. All the best, HaraldMicrosoft Teams API Capabilities
Good morning, We are contacting you to find out whether it is possible to achieve the following functionalities through the Microsoft Teams API: Start a scheduled meeting automatically Through a voice command, a meeting scheduled in a room's calendar is automatically started, and all the necessary equipment and services are activated without any user intervention. Automatically answer an incoming call in a meeting room When a call is placed to a specific account, the room automatically answers the call without requiring any user action. Add participants to an ongoing call or meeting Allows new attendees to be added to an active meeting or call in progress. Thank you in advance for your assistance. Kind regards,
Regarding Teams Meeting Media Transport Behavior in VDI Optimization Scenario
Hello Microsoft Teams Engineering Team, I am currently working on a Browser Content Redirection / media offload implementation for a VDI environment, where WebRTC media transport is handled through a local native component while the Teams application continues running inside the virtual desktop session. While testing, I observed that: 1:1 calls successfully receive audio and video media But in meetings auido / video RTP is never forwarded despite successful ICE, DTLS, and SRTP establishment DTLS ApplicationData traffic is present during meetings, suggesting DataChannel/SCTP activity Based on transport-level observations, it appears that Teams meetings may rely on SCTP/DataChannel communication for SFU video subscription management, while 1:1 calls do not require the same subscription flow. I wanted to ask whether: Teams meeting video forwarding depends on active bidirectional SCTP/DataChannel connectivity Meeting video subscriptions are expected to be coordinated over the WebRTC data channel/control plane Split ownership of media transport and control-plane transport could affect expected Teams meeting behavior in VDI optimization scenarios Thank you for your time and guidance. Best regards,Rajdev
Feature Request: Real-Time Multilingual Voice Translation in Microsoft Teams
Hello Microsoft Teams Community, I would like to suggest a feature for Microsoft Teams that could help multilingual users communicate more naturally during meetings. Feature Idea: Each participant can speak in their own native language, and Teams will automatically translate and play the speech audio in the listener’s selected language in real time. Example: Telugu speaker talks in Telugu Kannada user hears Kannada audio Hindi user hears Hindi audio English user hears English audio This would be more powerful than subtitles because users can continue conversations naturally in their mother tongue without needing to read captions constantly. Possible Technologies: Speech-to-Text AI Translation Text-to-Speech Real-Time Voice Streaming Benefits: Better communication in multilingual countries like India Improved accessibility Easier collaboration for global teams More inclusive meetings I believe this feature could significantly improve communication in international and regional meetings. Thank you.
Is there a way to get live transcript in Microsoft Teams?
I am trying to find a way in Microsoft Teams to get the live transcript, I want to be able to subscribe to a meeting/call that it is still running and to get the transcript from it. I understand that there is an Graph API that allows me to get the transcript for a meeting/call that ended, but that's not what I need. I am alright even with faking the subscription and do a HTTP call every 2-5/seconds. After I get the transcript I would like to do some live processing on the text. I am aware that I can connect a bot to a meeting/call and then the bot can interact with the audio stream and use Azure AI Speech Service to convert the Speech-To-Text and get the live text. I found a sample in Microsoft Github repos: https://github.com/microsoftgraph/microsoft-graph-comms-samples/tree/master/Samples/PublicSamples/EchoBot This is a good solution, but if possible I would like to do be able to do one of the following, if possible: get the transcript without a bot that needs to be connected to a session. connect a bot that can interact with the live transcript in order to get all additional metadata, like speaker name.Add Teams Chat Member API call inexplicably Failing
I have tried every possible permutation of this API call that I can imagine. Nothing works. I already started a thread on this, but now it appears to be glitched and I can no longer reply to message sin that thread for some reason. What can I do to contact Microsoft Support and speak directly to their API team? The responses I have gotten all appear to be AI generated and NONE ARE CORRECT. I really need help, from a human, that actually might understand what's going on here. Please help. "#microsoft.graph.aadUserConversationMember' for 'odata.type' is not valid for this operation." <- I am receiving this error despite the fact that we already have several users in this channel with that same type. This API call is intended to invite a user to an existing group chat. This should really be a very simple thing. 1. ALL users in the group chat already have type = '#microsoft.graph.aadUserConversationMember' so the error message doesn't even make sense. 2. This IS a Group chat. NOT a channel. NOT a one on one chat. 3. The Inviter has permission to invite users to this groupchat through the frontend. (and in fact can do so using the frontend.) Why is this API call failing? I have tried scrubbing the API call of special characters, I have tried using the beta endpoint, I have tried several different formats for the input. ERROR: {"error":{"code":"BadRequest","message":"The provided '#microsoft.graph.aadUserConversationMember' for 'odata.type' is not valid for this operation.","innerError":{"date":"2026-02-10T19:11:28","request-id":"XXXXX","client-request-id":"XXXXXX"}}} POST URL: https://graph.microsoft.com/v1.0/chats/IDHERE/members BODY: { "chatType": "group", "\u0040odata.type": "#microsoft.graph.aadUserConversationMember", "user\u0040odata.bind": "https://graph.microsoft.com/v1.0/users/IDHERE", "roles": [] }
Status during a Teams call : "in a call" only once others have joined!
Hi, I work remotely so most of my job is through Teams calls with laypeople (i.e. not necessarily Teams savvy). I like to start the calls a few minutes before to prepare my shared whiteboard, etc., make sure sound is OK... However, the status, even when I'm alone, is automatically "in a call" and so I don't have notifications anymore, which is generally OK, except that if my client tries to call me on the phone (which is on Teams), they go directly to voicemail. It is annoying to manually switch it. I think that when we are ALONE in the call, waiting for others to join, we should appear as AVAILABLE so that all notifications, etc. are still enabled until we are not alone in the meeting... and then, yes, all the do not disturb aspects must kick in! Thanks!
Meeting Bot issue: Did not receive valid response for JoinCall request from call modality controller
I'm trying to join a Teams Meeting with a bot. I used this https://microsoftgraph.github.io/microsoft-graph-comms-samples/docs/articles/index.html#making-an-outbound-call-to-join-an-existing-microsoft-teams-meeting sample. When the bot attempts to join I get the popup to admit or deny it in the meeting, but as soon as I click admit, it drops. In the logs I see this message: Call status updated to Terminated - Did not receive valid response for JoinCall request from call modality controller.. DiagCode: 580#5426.@ I am using the latest (1.2.0.10563 at time of writing) version of Microsoft.Graph.Communications libraries and the problem only started after I updated from 1.2.0.3742 that I was using previously. I could not find any info on what the call modality controller is, or how to check what it is responding if anything. Any ideas on how to troublshoot this are welcome.
