We have had reports from a user we are a reseller for that they are receiving a number of blank voicemail and callers are complaining they are leaving voicemails. I've checked over a recent report and can see that there is significant talk time in each of the instances where the audio in the file is blank. From checking a mail trace there are also instances of only one email being sent but the report is showing two voicemails were left in a short period. See the example below, the user received an email for the 3.53pm instance which was 00:00:00 in duration but no email for the 3.54pm voicemail that was apparently also left from the same number.
We are using the 3CX SMTP server from emails and there was no issues testing. We also placed a few test calls and could not replicate this issue but this has happened for this user on multiple occasions over the last week. I can see a number of 3CX users have reported similar issues over the last few years but have seen 3CX advise this was resolved in updates years back. Any assistance would be greatly appreciated!
