Thats a pretty basic TAPI application (ie microsoft). Basically it's a serial port on the phone connected to the computer running a TAPI compliant driver.

DID..you said you are using 6 ISDN lines. I am not familliar with Ireland's ISDN but if it's like US ISDN you cannot do poor mans DID on BRI unless you get more than 2 SPIDS on the channels..and the only system that I have seen that can seperate these properly is Tadiran (Sprint). If you are using PRI this is no problem. If you are using regular DID channels I don't think you can get caller ID and thats a problem doing screen pops.

I would get VERY specific on how they plan to do what you want and in writing on how it should work. I have seen people lowball then, hit you with an OH by the way.

Good luck!
