It’s interesting to see that there are some cheap options opening up in the area of computer-telephony integration, thanks to the growing popularity of VoIP and associated equipment.
I spent a few months researching and playing with CTI a while back, in support of a client’s project that would have integrated real-time telephony into a web-based application. I found CTI pretty fascinating. Now that these cards are getting cheap, I might look at learning some more about the topic. Couldn’t hurt to have that and VoIP in my consultant’s bag-of-tricks…
(I saw the above product link in an article on building a personal PBX that looks pretty good.)
