I know you probably thought of this, but did you ever record the message someplace else or possibly have it playing while shooting a home video during a birthday or an anniversary? Probably a remote possibility, but you never know. Since you didn’t record over it, there might be a possibility of retrieving it. I really hope so! Please let us know what happens.
Yes. As the voicemail greeting is the first thing your calls hear as in the examples above, the On-Hold message is the really important part if you have to ask your customers or clients to hold. No one ever likes to be on hold, but if you don't have a professionally structured on-hold system set up, it is worse for them to sit and wait. On-hold messages can be set up to include just music, which with the right music will keep your calls more relaxed during the hold time, especially longer holds. On-hold time should be best utilized to further build your company brand, or offer suggestions and info to guide the caller to ask more questions when with a live operator or you. ...music playing.... Thank you for holding we will be with you in a moment. Did you know (company name) offers this and that service along with the service you have. Ask a representative when we come on the line how this can benefit you today. ....music continues for 15 seconds... We appreciate your business, thank you for continuing to hold. We at (company) strive to give you the best possible products at the best prices. Did you know you can get a (product) this week only for ($). Tell the representative you heard this offer while waiting and we can get you all the details. On-hold messages can include whatever you want and will often just loop from end to beginning as the customer or client is on hold. Think of it as a way you can advertise to your own customers as they wait.

If you're still with me, leave your name and number and they will get back to you. This is not a voicemail; this is a telepathic thought-recording device. After the tone, think about your name, your reason for calling, and a number where I can reach you and I'll think about returning your call. Hello, this is Death.
