You can try emailing them using this contact information. Also, you can try calling at different times. I believe it is based in Wisconsin; that should help in picking out times respecting the time zone.

well if your calling YOUR number and don't have voice mail setup you will get a busy signal.. your also being charge for call.... so call yourself anytime and see if someone picks-up.

Hello Julie
I am Dr. Matthew Ray CEO at Titan Security
Can you tell me how you get this busy tone, by dialing a number
or just picking up the phone. I need the model number and more information. You can email me at [email protected] OR you can simply comment. Thanks

Before voice mail will answer, the phone has to be programmed to forward to the voice mail pilot number on a busy and no-answer condition. Example, if your voice mail system is on extn 555 then program the phone to roll over busy/no answer to ext 555. (there will need to be a companion mailbox on the voice mail system that matches your extension). Hope this helps.

Hello,

Go to settings on your phone, click on the phone option, it will display different option, select call forwarding or call divert, enter the number you forwarding the call to and press ok, you are done. follow the same procedure, when you get to call forwarding, you can select to cancel as you can no longer add a number.

Take care.

Take a cell-phone, and dial the telephone-number that you are giving to your customers. Does it ring? Does the FAX "pick-up" the call?
Or, do you get a "busy" signal?

Check the fax line with a regular phone and dial a fax number to listen for fax tones.

From your description it sounds that you have a short on your Line 1. Its either on DMarc of your carrier or it cross connected improperly. However your post is not clear on voicemail. In normal operation if busy it doesnt go to voicemail.
Call your carrier first and report troubled line. Their technician will tell you what to do next.

I was given a set of codes to use to reset the "make busy" sign, which was **1, not sure if these codes pertain to all phones, and to turn off "head set" i was told to use **3. I was then able to see the date and time again!! I also was able to pick up my phone when it rings instead of having to press a certain ext to answer from.
Good luck!
