This was an option before the 2017 software update. It saved time because it avoided having to login to Phonebooth and manually delete the voicemail already delivered and acted upon via the email notification alone.
Is it possible to reconfigure settings on the user end to enable this feature? If so, please describe the necessary steps.
If not, is this feature able to be re-enabled manually by Phonebooth?
If neither is an option, could you please consider re-enabling it, or describing why it's no longer feasible?
Thank you for your help.
