In reality, that's when you can bump into voice quality problems. Your IT staff not only can't control those home routers remotely, they often won't even know their capabilities. These routers were either chosen by the employee or by the employee's ISP, so even in a midsized company, you're looking at hundreds of different makes and models. Some will have more advanced features, like QoS, some won't. Those that do may also implement QoS and similar features in different ways.
Most people screen their phone calls and often avoid answering unknown numbers. If you’re applying for new positions, you should try to view each unexpected call as an exciting opportunity! In the event that you simply can’t pick up the phone, you’ll want a polished voicemail greeting to let the caller know they’ve reached the right person.

If your customers feel that you don’t care, they’ll take their business elsewhere. Experiences are the differentiating factor between businesses. Big efforts to improve the overall experience in tiny ways by crafting a voicemail greeting script can make a huge difference when customers are asked by their friends and family how easy it was to work with you. And word spreads quickly in the age of social media. The more positive experiences you offer, even when you’re not available, the more likely those people will call back.
Put some thought into your message before you hit “record.” It takes very little time to write a script for yourself to read as you record your greeting. Reading off a script eliminates unnecessary pauses, “ums” and “ahs.”
