It's easy to get carried away in a voicemail and include more detail than is necessary. We've all been in that situation where the automated or pre-recorded voice on the end of the line goes on and on with more information than you can take in.
When making an investment in a new phone system that needs to integrate with other systems, the Switchvox system makes the most sense. Regardless of how your business changes and grows, your initial investment is always protected. Using standard IVR/XML scripting, you can easily connect your database and create steps to take your caller almost any direction you can dream without having to know anything about phones or phone system software! For example, a school might offer parents a custom absentee line to quickly report student absences or a company may route new callers to sales people but existing clients are routed directly to a customer success team automatically based only on the Caller ID.

Your voicemail needs to have relevant information such as your name, who the prospects are connecting to, the department you work in, why your not available to assist your prospects, when you will call them and related information, this is what the prospects would prefer hearing instead of dragging the voicemail messages speaking about your brand and more.
You can assign a business hours schedule created previously, or create your own business hours schedule for the auto attendant.
