Bot status changes from Establishing to Terminated - Unable to Add Bot in the meeting

Hello, I'm trying to get my bot into a meeting.
I get all status working fine, when it comes to actually join, it fails.

The Bot Call status goes from state "Establishing" to "Terminated" which I debuged from the code itself.

      `"message": "Server Internal Error. DiagCode: 500#3002.@",`

There is no documentation or help on this issue. How can I find and fix the source of the issue?
I have been working on the PSI bot for quite sometime and this is the 3rd time this issue has occured out of no where. 2 days back, everything was working fine and suddenly the bot fails to join the meeting and I get this error everytime.

Start by reviewing the bot's meeting-join flow and the logs for the Establishing-to-Terminated transition, especially result code 500 and subcode 3002. Use the provided LegID, CallID, tenant, and meeting identifiers to correlate the failure. Done means identifying a reproducible cause and documenting or applying a verified fix, but the issue names no repository files or tests.
