I'm a Legacy Nortel PBX Dinosaur. Still working on Nortel as well as Avaya, ShoreTel and our own Hosted VOIP. Started in 1979 with 1A2 Key Systems, then Electronic key, Mitel SX20, 100 and 200. Lots of other products along the way. Full time Nortel guy since 1991 when I got a real job instead of mom and pop companies. Got in the business by chance. I had Vocational Training my senior year of High School and was going to follow my Dad's career path in machine shop. I was only 17 when I graduated so I had about 3 months before I could take my job at a local machine shop, had to be 18. I went to work on a temporary basis, so I thought, with a job pulling phone cable. That was 35 years ago and I'm still in the business. I hope it lasts another 10 years or so. I will be 54 this year. It's been a good gig. Sometimes I wish I would have done something else. But the customer interaction I really like. Most people are nice to the phone guy.
