Take the time to listen to calls, call back if necessary, use your cell phone when you’re out of town, and take care of anything actionable listed in the messages instead of watching your mailbox fill in. This kind of attention to detail can go a long way towards building a good reputation and image for the business. Good luck! Search
First of all, I want to say great work on using the phrasal verb “to pick up!” Native English speakers love phrasal verbs and we use them often. In this example, to pick up the phone means to answer the phone.

In the case that your business is closed due to an emergency, it's only worth it to go into detail if the problem is affecting everyone in the area. Otherwise, stick to your Company Wide Voicemail Greeting, but remove the stated hours and tell callers that you're currently closed. Thank you for calling Cutlass Technology.

The above section details types of phrasing to avoid; however, it doesn’t detail what users should NOT say on their greeting. Though this is a bit loaded, as there are hundreds of combinations of things one shouldn’t say, there are some key components users should ALWAYS avoid. a. Forget About Slang: You should strive to be as professional and welcoming as possible in your greeting. While this may steer you towards using slang, in an attempt to make callers comfortable, it’ll most likely work against you. As a professional, your demeanor, tone, and speech should be clear cut and well articulated. Using slang undercuts this and works against you. b. Don’t Even Think About Profanity: This is a no-brainer. Never, under any circumstances, curse in your greeting EVER! c. Keep Your Sentences Clean, Don’t Ramble: Introduce yourself and give your caller specific direction. Avoid long diatribes detailing tangent thoughts. Keep it simple and quick. d. Always Return Your Calls: It’s important for callers to feel they are valued. Nothing dissolves this quicker than a greeting that doesn’t stress this. For example, “I’ll call you when I can,” “If I don’t return your call, please call back”—these phrases are terrible and completely destroy any good will you may have with a caller.
