Using an on-site PBX means you own the hardware of your phone system. You can modify the system to you exacting specifications, including changing phone numbers and adding extensions as necessary. You will also be in charge of ensuring the security of your data stores such as phone number listings and voicemail recordings.
A voicemail greeting, on the other hand, refers to the message that your callers hear upon answering the phone. Voicemail greetings can include any information you’d wish to convey, such as special sales, bargains, alternate phone numbers to use, or your company’s normal working hours.

It’s more important that your callers feel like they can ask you for help on a subject they don’t know too well. A really easy way of simplifying your greetings is by using smaller words. Imagine yourself explaining what you want to a three-year-old. Your customers aren’t stupid, but they’re not going to always be familiar with typical business jargon. Make sure you’re adjusting your greetings to accommodate for the lack of familiarity, unnecessary details, and technical information.
