I got a call today to look at a, hopefully new customer, SBX voicemail problem tomorrow. The customer tells me, that when a caller leaves them a voice message, and when they listen to the message, they have dead spots through the message. They hear the first couple words, then nothing, then some more message, blank, etc. They said, they usually end up calling the person back, because most of the message they left, is missing. They were using a different vendor, but have had a falling out over this response to this problem. I know they said he replaced the card, but they still having the same trouble. If anyone has had this issue before and have some insight into fixing it, that would be great.
