We purchased a BCM400. I won't say names but a very large telecommunications company sold us the system and then really didn't know what they were doing when they installed it. Unfortunately the only other vendor in my area was way out on installs. Anyway, I see that it says I have 9 "Active" IP Client Seats. So I assume that means I can use 9 IP phones or i2050 clients? The installer had no idea. Now everytime I call they charge me $250 for a "change". If that's the case then I'm having problems. I can't get the i2050 software to connect to the system. Or I should say I think it connects but the first thing it wants is a password. I've tried "0000" and that didn't work. So my question is how do I configure my soft phones and/or IP phones to work with this system?
