That rich feature fabric can change radically between vendors, however. For example, RingCentral's softphone offers a long list of app integrations and features, including not just collaboration platforms, but bi-directional email and scheduling among other things. Line2's softphone client, on the other hand, is specifically designed to be simple so users can pick it up quickly, and it does this by mostly mirroring the buttons you'd find on a standard desktop handset. Two ends of the spectrum, but that means you need to be very careful when testing these apps to make sure you're getting not only what you need but in the right way for how your company does work.
A good voicemail greeting is short and professional, lets people know that you’ll get back to them, and invites callers to continue engaging with a call-to-action. You should also show your personality if you’re in an industry or role that allows that. If your industry is more conservative, however, you’ll want to keep humor and personal touches to a minimum. A greeting Your name Your company A simple explanation for missing the call (e.g. you’re away from the phone or are on holiday) A rough estimate of when you’ll get back to the person An alternative person to reach out to (if you’re out of office) An alternative mode of communication (if you prefer email or text) A call-to-action such as “Leave a message” or “Send me an email at [email protected]”
