I have a customer with a Legend 7.0 with Duvoice PAL voice mail, currently 4 port. I have an expansion card with 4 more ports to install, but cannot get the duvoice to recognize the additional ports. Please help?
The documentation with the expansion card shows me how to set the jumpers, but not how to determine the base I/O address. Computers are not my strength. Is there a relatively ease way to determine the address?
