When or if you had issues or Adds, moves or changes, did you call this company and have them remote into your system and change them??? Did this company monitor your outages via remote? IF so there is a device that connects them to your PBX. It will take place of a modem or on the IP network. IF you have this, that is what they probably want back or something..Did you ask them?
