I have my incoming voicemails sent automatically to my Gmail account. Gmail cannot automatically play the way files and I have to download them to play them.
Is there a way to specify that these e-mails be sent in mp3 format instead of wav?
By now is not possible. To achieve what you request, we have to create a special script that will converts wav files to mp3 and then send to the specified email address.
However, we don’t discard the possibility to add this functionality in future versions of VitalPBX.
