You can change your information and hold music as often as needed to reflect changes with your product or service.
Most companies have one on hold message and music recording produced and then update every year or two. Other clients change their hold messages with each new season or have chosen to update their program monthly to offer specials and announce other dated information. New messages can be coordinated to present special events, roll out a new product line, or any other custom needs.
Please also consider the following: Do you receive frequent calls from the same people or do you tend to have a steady stream of new customers? Keeping your on hold message fresh has proven to be more effective when marketing to repeat callers.
