FSK Signal For Voicemail on MCI

I have MCI as my local carrier and subscribe to MCI's CID and voicemail service. I recently purchased a new phone that has a voicmail indicator. However, when I have voicemail, the indicator does not work. The manual for the phone states I need a FSK signal for the indicator to work. Emails and calls to MCI have proved fruitless when I ask if MCI supports FSK for VM notification. No one seems to know what I'm talking about. Does anyone here know if MCI local service provides a FSK signal for VM?

Thanks.
