I have a Partner acs R4.0 been installed for 8 years. 2-slot
carrier, 206 card in slot 2. I'm at sta.10, another person makes
a call on line 1 from another phone, then sta 10 grabs line 4,
light is green no sound until it times out with ROH tone. I pick
up the line and hang up. Customer says sometimes they can't hang
up the line and all the lines will get hung up. I did a system
reset, then a system default, no luck. Customer says someone else needs to be on a call to start this sequence and they can't
hang up the lines until that call is terminated. Any ideas?
Thanks
