Voicemail not being delivered from Phone System to Exchange 2013

After having this discussion in the Teams forum, I have a theory that the issue I'm seeing is specific to the Canadian geo. Is there anyone else out there with their SfB tenant in Canada and is using Phone System who saw a change to the delivery of voicemail around mid-October? This may have affected you even if your email is in Exchange Online. For example, incoming voicemail messages may be now be acted upon by mailbox rules, whereas previously they were unaffected. Voicemail playback controls in Outlook may not be appearing for voicemails received after that date.
