To develop IVRS, you need the following hardware and software tools

1. Hardware
2. Software

1. Hardware
1. PC – Available readily. Check your vendor if warranty becomes void when you open the chassis of the PC. Because you will open the PC to install CTI hardware.
2. CTI Cards.
There are many CTI vendors. And then there is Dialogic. Dialogic is now a EICON Company. Here is the list :
a. Dialogic – All kinds of CTI boards available. And very good SDK(Software Development Kit). Costly. The CTI bigboss.
b. Brooktrout – well, it has also become a Dialogic Company now.
c. ALTEDGE Boards – They have TAPI compliant analog boards.
d. Donjin JCT boards – Analog and Digital Voice Boards
e. Comtek 4 Port – Analog Boards
There may be more companies who manufacture low cost CTI cards. I will keep updating them. Intel is the shark in CTI hardware who is buying out competitors!
3. Emergency Power back.
4. EPABX with 3 to 4 extensions for testing and for analog CTI cards. For digital cards, I hope you should attempt to develop at home. You need costlier infrastructure then IVRS itself!

2. Software
What to choose to develop IVR Software ? Here are the available tools
a. Good Old C and C++ : Almost all CTI Hardware vendors provide SDKs for C and C++! My personal favorite.
b. Voice Guide : Good Tool to develop IVRS fast! Supports variety of CTI hardware.
c. CT Developer Studio 2 : Visual tool, very easy to use.
d. AGE : Fastest IVR application development tools.
e. Eurovoice objects version 2.0 : Simple and easy tool to develop IVR Software.
f. Xtend IVR : Excellent Tool! The best Part is it has free 1 port tool available for downloading!

That’s all folks! Buy any of the above and develop your IVR! Keep checking this blog, I will keep posting various details about both CTI hardware and Software Tools above! Also if I have missed out any IVR Software tools or CTI vendors/cards, please comment me or shout me at TECHNICAL DISCUSSION!
