Okay, station IDs are all set to '0' for 'keyset' by default, so I'm not sure if anything there needs to be changed. We've got five incoming lines, so I do have more ports than actual lines. How do I place the unused port into a trunk group? The manual doesn't use the exact same language and I'm a little fuzzy on proper procedure. Also, multi line phones are ringing, but SLT phones do not. Thanks so much for everyone's help. I feel like I'm learning a heck of a lot in a short time from some very experienced people.
