Typically, most of these services are uniform—i.e. include the same tools and features (send a script, they record it in a tone you approve, they send it as a file, you supply any feedback, etc.); however, there are some services that go above and beyond. For example, VoiceOverPro, is a single voice professional who records 30 second voicemail messages based on users’ scripts. This is standard; however, users also have options like adding music, recording up to 60 seconds (or 150 words), rush, 2-day turnaround, and even same day delivery.
Solution: Poor sound quality is unlikely the fault of a reliable business voicemail service that uses VoIP technology, Baldwin says. So garbled voicemails are often due to callers’ poor mobile phone reception while leaving their message—and you may just need to call them back, assuming you can figure out their phone number. But if the problem does seem to be your voicemail, make sure you’re using a business phone and voicemail service that uses VoIP and not relying on, say, your mobile phone’s voice mailbox.

Having a dedicated emergency contact will help make sure anything important that comes up is taken care of. Another option is directing callers to a separate answering service.
First, open your mailbox for the first time. To open your mailbox from your telephone: Dial 083210. Enter your area code without the zero and your telephone number eg. 9 123 4567 (this is your temporary PIN). Enter a new PIN and decide whether to have PIN protected access. Press #. You are now at the main menu. Follow the voice prompts to set up your mailbox.
