A part of Outside the Box Project (focusing on outside the US-based office telephony market)
Japan had a huge influence in the US telephony market, which would be an understatement to admit. While Nortel had the Norstar, and AT&T (later Lucent then Avaya) had the Merlin family and Partner and later IP Office, some offices had their comfort in Strata, Omega, or KX-xx.
