The only problem I have with the voices is that the French and Spanish ones are really hard to understand. It’s almost like the voices are speaking English words based solely on French and Spanish phonetic rules, instead of sounding like English in a French or Spanish accent. Either way, it was a jolly good time, and I recommend that you at least play with the app, if not actually use it on a regular basis.
Reassuring the caller that they contacted the correct number or reached the person they intended helps reduce the number of hang-ups and wasted messages you’ll receive. Here are a few notes on how to leave the best greeting possible, along with some voicemail message examples you can use in your own company!

Microsoft continues to ride roughshod over people who have been users - at not inconsiderable expense - for YEARS. Skype itself is NOT free to use (even leaving aside my paid phone number) because it wastes hours and causes anxiety and frustration, each of which has a cost. Skype was never perfect but it had some degree of honesty before it was swallowed up by Microsoft.
If you don’t make any changes the default iPhone voicemail message is pretty bland and not very professional. It is a good idea to change the iPhone voicemail message to something more professional or at least something that lets callers know they reached the right person.
