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.
One major pain point for any business is when customers aren’t going into a phone call or meeting prepared. If, for example, you’re a lawyer, you need your clients to come prepared with their documents ready. You also know that there are a ton of papers that need to be organized and filed — often with tight deadlines as well — and it’s imperative for the client to have it all readily accessible.

Telling a quick joke or including a little more information can keep you safely within the 20-second timeframe while letting the caller understand a little more about you.
