Do not purchase any Cbeyond services. I did and it's the worst nightmare ever.
After the installation, I had no voice mail for 7 days and all Cbeyond did was create tickets and never called back. Our cell phones did not work correctly and the T1 is horrible and very slow. I tried to port my numbers to another carrier and they kept on refusing the new company stating that they were not sending over the correct information to port the numbers. They did have all the correct information, but refused to port.
Now my phone is turned off and I have lost my number which I have had for 15 years. Talk about losing business or losing my whole business. I will be getting an attorney regarding this situation.
If anyone else has had the same problem, please let me know.
