Resetting company voicemail

First, there are two things you need to know. The DKT3010 phone will work on different Toshiba phone systems AND you can have different voice mail systems. The phone system and voice mail are separate to some extent. You need to know the model of the Toshiba main control unit and it would help to know for sure which voice mail system you have.

You SHOULD have an administrator's guide for the system and voice mail or someone at the office in control of making simple changes to the system... however, depending on the company that originally installed the system you may have gotten nothing (hopefully they are still in business and you know who they are!!) Most of these systems can be programmed over the phone quickly by the company that originally installed it. There are probably passwords that you would need to know to change any programming features and if you don't know what they are you would be out of luck.

Your best bet is to find the company that installed the system. There may even be a sticker on the main control unit with their contact info. Next I would try to find a local installation company that could help you get the changes made and set you up with a way to make future simple changes yourself. Get ALL the information needed to make any changes like passwords etc.. even if you do not want to do it yourself, you NEED to have this information in case the company goes out of business!
