Not all business telephone systems are on-hold compatible. In some cases older phone systems might need a module to enable on-hold messaging.

At no charge Mac Donald Audio can quickly and efficiently ascertain your phone system’s on-hold capabilities. To find out if your phone system is on-hold compatible, please click on the e-mail icon and make sure to include the following information:

• Name brand and model number of the phone system
• Where the phone system was purchased
• Contact information of the company that supports your telephone system

In your e-mail please indicate that you would like to find a company to service your phone system. Mac Donald Audio will provide these services free of charge, whether or not you choose to select Mac Donald Audio as your messaging provider.
