Here comes the bad news: I have a few complaints about the app, most of which could ultimately be resolved in a software update. The first is the voices, as I’ve already said. Secondly, the app UI isn’t all that smooth. I found myself tapping buttons three or four times before I got a response, and that was over a pretty solid WiFi connection. Luckily, little stuff like that can be fixed in an update, and we hope that the folks at Orange Vallée get that cleaned up soon.

Voicemails need to maintain a professional consistency that’s aligned with the entity it’s representing. That said, the structure can vary depending on the situation.

The service also recommends stating your name, apologizing for missing the call and that you will call them back. If possible include a time frame for a return call. Don’t ramble or include un-needed information.
