Bot deployed in AKS bot doesn't join the meeting with the MediaControllerConversationAddParticipantFailed error

Describe the issue
Hi all,
We try to deploy our bot to AKS by guide
https://github.com/microsoftgraph/microsoft-graph-comms-samples/blob/master/Samples/V1.0Samples/AksSamples/teams-recording-bot/docs/deploy/aks.md#create-bot-channels-registration

We had configured it, the bot is accessible by HTTP and can receive incoming events. When we try to send a join request on /joincall endpoint, we get a response 200 - OK. But then the Bot doesn't join the meeting. We get a MediaControllerConversationAddParticipantFailed error. But locally the Bot in a container works via ngrok.

Logs of the call attached below

Expected behavior
Bot joins to the meeting.

Graph SDK (please complete the following information):
Microsoft.Graph.Communications.Calls.Media v1.2.0.850
Microsoft.Skype.Bots.Media v1.17.0.39-alpha

Please help to resolve that issue. That is stopping us from going to prod. Thank you.

Start with the deployment guide at Samples/V1.0Samples/AksSamples/teams-recording-bot/docs/deploy/aks.md, then trace the /joincall request and the attached MediaControllerConversationAddParticipantFailed logs. Compare the AKS deployment with the working local container setup; done means the deployed bot joins the meeting successfully.
