Client has an old analog Viking system going into Key System. They are finally changing it out for a hosted VOIP system. The system provider wants us to to add a few components to the system but we need help with wiring. Here's the current layout and the new layout OLD Viking DP>Viking C2000B>NEC KEY SYSTEM CO PORT NEW Viking DP>VIking C2000B>Viking TBB-1B Booster>Viking K1900-Dialer>Mediatrix Port I assume I go from the C2000 to the 1B input port and out to the Phone port of the dialer and plug the line port into the Mediatrix. Is that correct or do I have things mixed up? Many thanks.
