I had a call from a new customer that has a sts system. The dealer that sold the system told customer that he need to down load new software for the caller to work correctly. Accotding to cust he started it but never finished it and waa never heard frome again. I know nothing about tha system, I did install a signal line phone, but the caller id is not working and he would like start outgoing calls on line 2 then 1 only. i got the manual but can't access the program for caller id. ANY HELP
