We have three DeKolink wirless 800/900 Compact BDA repeaters/recievers (Models: MW-CBDA-SMR800-900-1W65) for our nextels, located in three seperate buildings of cours. Well our second building located in the middle of our complex seems to be dropping calls all the time so unsure if it is the dekolink system or what. Would like to get assistance on who I can get to come out to inspect it to make sure they are working properly or figure out the issue.
