Question : How can I connect two T1 lines together for increased bandwidth?
I am ordering 2 new T1 lines for my company, one with 16 analog VOIP lines, and the other with IP internet services only. My ISP tells me they can only connect the two lines together if I get a digital VOIP line, but our phone system isn’t compatible with digital lines.

My problem is that I am throwing away a lot of usable bandwidth on the VOIP T1 line that can be used to supplement our data T1 line. Is there any device on the market that will allow me to bridge these two connections?

Thanks in Advance!
A new PBX system (which I did look into) will cost us about $ 25,000. My bosses will not spend the extra 25k for a phone system just to get some bandwidth. The Idea behind going with VOIP was to save on the phone bills compared to a Telco line. If I were to say lets spend an extra 25k to get a new phone system to, then I would have no T1 line at all, and we would keep our slow 384k DSL service.

Ask about a T3 line.
