We ran into an issue a couple weeks back with one of our comm servers for access control and he was able to help me get all of the access control panels associated with the comm server back online within a few days. He was able to help me out with locations, getting info that some panels were DHCP and him providing us with new static IP’s. He was a tremendous help." - Anthony Marquez - Signal Tech
