I have been in the telecom business since 1988 starting with cable contracting direct with Bell Canada then moving onto installation & programming of Nortel & NEC systems with a couple companies, eventually starting my own company, www.TelcoPC.ca in Toronto.
I have currently only focus on Nortel Norstar & Business Communication Manager (BCM) including keycodes/modifications.
I am now looking to provide our clients with Voip.MS services which I have been running on my own BCM system for about a dozen years.
