Departments and teams are typically organized by function – customer service, tech support, sales, billing questions, etc. When a team is busy handling other calls, encourage your callers to leave a message and reassure them that you will get back to them within a reasonable time frame. It’s important that you actually follow through to avoid upsetting your callers.
Whether it’s an out-of-stock product, a canceled event, or social media snafu, there are times when your business may see an influx of frustrated callers. While it is important to address their concerns head-on, you may not be able to answer each call as it’s received. Make sure you use best practices for dealing with angry customers, and that your voicemail greeting sets the appropriate tone. Avoid defensive language, validate their concerns, and keep them informed as to how you are handling the situation.

As greeting messages should reflect your mood and your personality, they must be recorded with utmost care and with the right choice of words. Here are a few examples which you can make use of while recording your own greeting messages.
