Got an odd issue. We have an FXS card with our fax number of 0267. When we call the number, it will go to a general greeting. I don't know why the line is being forwarded to the general voice greeting. We haven't messed with any settings on the FXS but we did create a new auto-attendant recording for our general number. However, we were careful not to use any number that was using the 0267 number.
I have attached a doc that shows the setup.
