The system isn't releasing the calls because it is not being instructed to do so. Your system is either not receiving the loop supervision disconnect signal (99% of the cases) or the system is not programmed properly to interpret it. This is through no fault of the phone system OR the voice mail. It is due to an errant programmer either at the telco or on your site.

The system(s) aren't terrible. They are doing the right thing by keeping the caller on the line because they aren't being told to release them.

Chris, VOIP isn't all digital. It still depends upon the equipment installed. With the exception of the SLT adapter connectivity to the voice mail, your current system is all digital.
