I'm trying to reach someone on their cellphone and am getting strange error messages. The phone will ring 4-5 times and then I get a message like this: "The Verizon Wireless customer you are trying to reach is not available at this time. Please try your call again later" and then gives a 5 digit error code. Texts appear to go through and I got texts back last week from this person, but i don't have any luck when I try to actually call them.

Has anyone else had this happen and was able to figure out what it means? It's someone who runs a business and that is their business cell, so I doubt I got blocked. I don't have any other ideas what might be going on.

I did try calling Verizon to see if they had any idea, but even they couldn't look up the error code!
