Well there is a Day mode, Mode A, Mode B, and Night. If mode A or B is programmed up and it's in that mode it could cause calls to be routed to a different location. Ask the recptionist to make sure it is set to true Day mode. You could also have her/him set the system to Night and try a test call. If it goes to VM then we know that's working. Then have her/him set it set back to Day and test again and see what happens. If it still goes off site them we have some sort of forwarding set somewhere and will need to look into that. How do the calls ring into the receptionist phone? On virtuals, or an ICI key? If it's virtuals try getting on each one and dialing the CFA cancel code which by default is #5.
