Hi, I am presently providing PC & network services to my clients. I would like to provide Telecom Services, specifically IP but I don't know where to effectivelly start. At the present time I do not have Telecomm staff. My questions are: a) What two-three systems are the most reliable, cost effective that could be used for boths small and large business? b) That has a good customer service and support? c) That I can be become a reseller withou having certifications? d)If certifications are needed, where can I get certified staff? e)Where can I get technical staff in WDC, VA, MD?

I am in the process of expanding my services to the Caribbean, South America and possible Africa, so good customer service and support online will be helpful. Any idea or suggestions will be highly appreciated.

Thanks,
Ulises (Willie)
