Hello Reza!
Seems like you are recycling your old extension. The text to speech option will no longer work if you are trying to recycle your extension by the time that the new update came.
I would suggest deleting the whole extension and re-do it.
The deleted extension will now go to Unassigned Extension
Please let me know if you have further questions!
Same issue. The work around is a pain. This is a bug not an enhancement. Should be fixed.
I was able to resolve this issue by changing "Ring Central Text-to-Speech" to "Record my name" then uploading or recording anything, save it. Reload the page, go back to user and change back to "Ring Central Text-to Speech" with the correct name in the user's settings and it works as intended. There is absolutely no need to rebuild an entire extension like the mod suggested.
Cameron Murphy thank you so much for your diligence in creating a workaround for this Text-to-Speech System bug.
