The software for Avaya Definity(and the newer names of Definity such as "Call Manager") products was made the same throughout the world years back. The feature set is the same, but different features are used in different parts of the world. Different power supplies are also sometimes used too. The E-1 standard for Europe is available in the USA, but only for a 'campus' non external uses.
On another note, this is my first posting in this forum, and I am going to have to control myself
"to not post any material which is knowingly false and/or defamatory, inaccurate, abusive, vulgar, hateful, harassing, obscene, profane, sexually oriented, threatening, invasive of a person's privacy, or otherwise violative of any law/", because that is against my nature, but I will do my best. :-P
