Graph API: create a PSTN call and invite a PSTN participant
Hello everybody, We are using the MS Graph API within a C# project. After successful creating a PSTN call from our bot like described here https://docs.microsoft.com/en-us/graph/api/application-...
Could you please share the doc or steps that you have followed to setup the bot with PSTN?
Have you any news regarding this issue? Our customer is waiting and gets impatient ...
- We have tried this but right we are not having the repro. I will update you as soon we get anything.
Thanks- Any update?
A peer-to-peer bot to PSTN call, works as expected, but we receive the following exception when adding a PSTN participant into a group call:
Code: 403

adrianpopa - We are confirm with the engineering team ,if bot wants to invite another PSTN to join, the P2P call will be escalated into a group call. So far we don't support escalation by adding PSTN. We are working on this feature now and it will be ready soon.
So, here are some scenarios:
1. P2P call between Bot and another peer (Teams user, PSTN), bot invites another PSTN: Not supported.
2. P2P call between Bot and another peer (Teams user, PSTN), bot invites another Teams user: Supported.
3. P2P call between Bot and another peer (Teams user, PSTN), bot invites another bot: Supported.
