I'm not sure if this number simply doesn't work or just wasn't operational for someone who isn't an Autodesk customer, but I had no success when trying to call this number. When I dialed, all I got was a busy signal. I tried again 15 minutes later and got the same result and then waited another 30 minutes and still had no luck.

Searching this number reveals that it's meant to be used as a phone number for Autodesk, but Autodesk really doesn't want to tell anyone that. You can't get access to the phone number on the website unless you've got an Autodesk account, as the company doesn't list it anywhere on its site. When you visit the "Contact Support" page, you're not given a phone number to call anyone unless you sign in to an existing account.

If you don't have an account, the best that Autodesk offers you is the chance to set up a chat with an agent on the website. Otherwise, it's not going to give up its customer service number. Searching on non-Autodesk sites reveals the phone number, with people complaining that they have to pay to get anyone on the phone with Autodesk.

According to screenshots from non-Autodesk sites, the company used to spell out that the phone was not available for non-subscribers, with the same restrictions in place for email. These days, the phone isn't listed as an option at all. If you sign into an Autodesk account, you are likely granted the phone number, but based on my experience, it doesn't seem to work properly anyway.

Unless the number is only workable to people who genuinely subscribe and there's some kind of trick to that, it seems that this should be considered a non-working phone number. Trying on multiple occasions yielded no results, and the company doesn't seem to offer anything to provide non-subscribers with a way to contact a live person at Autodesk.

I understand the need to both offer subscribers something for their money as well as the need to limit wasted time, but this seems to be excessive. There should be a way for potential customers to speak to someone and decide that they want to set up an account, without someone having to do it on their own. As it is, people have to decide to start a trial or make a purchase without any kind of guidance, which is far from ideal. Some companies in this situation offer one line for subscribers and one for general questions or an automated system, which would likely be a helpful solution that gave everyone an option.

Until they get this number fixed, I wouldn't use this number for anything.
