Quickly, return this Phone is you still have a chance, my small business used this phone for EXACLY 2 years, and now all lines are DEAD, NOT A SINGLE ONE WORKING. LINE ONE AND THREE HAVE NO DIAL TONE EXCEPT EXTREMELY LOUD STATICS. AND LINE 2 AND 4 ARE TOTALLY MUTED.
A lot of my customers are complaining about not being able to reach me in my office.

Hope this helps! Hal
