Thanks guys for the help thusfar, I've check out a few other things but one of my biggest problems is the office is in Texas and I'm in ATL, they inherited the phones from another vendor and no one knows anything about it. I did have a person onsite take pictures of the phone closet and they have an officeserv 7030 that appears to be connected to a Cbeyond device so I have ascertained they are using VOIP phones in the office but have analog service through Cbeyond (they confirmed the circuits were functioning with no errors). So I assuming the issue is in the 7030 but don't know how to proceed from here. I can remote access their network but have no idea how to login to the 7030 at this point. Any help is great! thanks guys!
