The last telco tech (AT&T) that was at our company checked the voltage of the line and monitored when the line was disconnected and when in route. He told me, "The Vodavi phone system is not giving a disconnect signal after receiving a message on the digital voice mail and the calling party disconnects."
I think I need to call a tech in. This is getting very frustrating.
I don't know if I mentioned this before, but we moved from McLeod (VOIP) to AT&T.
