I lost track of who now owns who, what company acquired another, etc. It seems most companies with a local reference in their name are gone, such as banks that have a state, city/town or region in their name. Southern New England Telephone was acquired by Frontier Communications a few years ago, I'll sometimes still refer to the local telco as SNET.
If anyone still works on the 5ESS or knows - I wonder if there's a way to have an extension, or TN, go directly to voicemail without being on a port, or LEN? We have many spare analog LENs with more to come, but I haven't come up with a way to do it yet. Looked at some main department numbers in the system that go to a menu, those were on LENs.
