Some Price Comparision of CTI Boards in India and IVR growth

I keep getting feedback/inquiries from various people asking about prices of CT(Computer Telephony) boards in India. Many people seem to quite puzzled to learn huge price ranges for similar boards with similar basic functionality. For example, depending on the manufacturer, one entry level model of one PRI ( E1) with 30 channels may cost anywhere between Rs. 10,000/- to Rs. 180,000/-.

Here is a price comparison :

CTI Board Street Prices in India

Though, I am unable to list prices of some other vendors here as well as CT boards with various capacities/configurations, but I hope the above list would be quite indicative. Dialogic with highest price tags still has the largest market share in a price sensitive market in India.

So, why is the price between the lowest and the highest CT Board is almost 10 times ? After all, a CT board is not ‘end product’ itself and it requires IVR applications or voice applications to provide the final solution.

Previously Chinese manufactured products were thought to be cheaper than products manufactured in other countries. But, Sangoma is Canada based company. Most probably, the basic difference between Sangoma and other boards is, Sangoma boards use processing power of HOST computer while other boards have on-board DSP ( Digital Signal Processors) to process various telecom protocol related functions. Many might argue that, with increasing MIPS in PCs, one should really not bother much about HOST PC processing for the CT boards too.

When one compares price of Dialogic boards with other cheaper cousins, one may wonder how can Dialogic survive in any price sensitive market ? I think here are the reasons :-

1. Dialogic has a huge developer base all around the world. After all, it is the oldest and biggest CTI company after merging with all its nearest rivals. It has very well documented APIs for all computer operating systems and lot of documentations available in internet for beginners.

2. Many RAD tools like VBVoice, OmniVox3D, Osidial etc. supports only Dialogic boards.

3. Most probably, Dialogic has the best support in CTI industry at present. They have very good support for both installation as well as developers.

The other cheaper alternatives like Sangoma, Digium etc. uses open source platform like Asterisk which has large developer community on net and growing. But, with almost 90% PCs in the world running on Windows Operating System, support of Windows is definitely a plus and with many RAD tools providers are surely competing well with Asterisk. For example, VBVoice is a toolkit which uses .NET! Now there must be millions of .NET developers in the world and when they find out VBVoice, they all become IVR developers overnight ( almost) and loyal fan of Dialogic boards as well.

Many people who are interested in IVR system, back out once they learn about the high price of CTI boards along with IVR software. The big price differences among similar boards confuse them more.

I have also attended mails from many engineering students interested in learning/doing college projects in CTI field and whenever I tell them price of 4 port Dialogic board, they always get discouraged. And when they ask for alternatives, I explain them about Asterisk based on Linux, they again get discouraged. Not many of them want to install Linux on their PCs. Almost everyone is very happy with their Windows machines.

So, I feel, Donjin and Synway are uniquely placed with their competitive pricing, good C++ Windows Based API. They have reasonably good support for developers.

    A solution to the boards dilemma is to not use boards at all. Host media processing is a viable alternative method of doing what you might want to do on a DSP board, but on the host PC instead. You are right, the processing power of today’s PCs means that channel count is not an issue. A 120 channel board will give you 120 IVR channels, but you need to buy a server in which it is installed. A decent standard commodity PC can run upwards of 700 channels of IVR and all you need to do is license the software, which can be very cost-effective. Then, if you need a PSTN connection – use a commodity gateway such as ApplianX (www.applianx.com ). Regarding the Linux/Windows dilemma; host media processing (e.g., Prosody S from Aculab – http://www.aculab.com ) is available on both Linux and Windows. So your students and developers can stick with what they like if that’s Windows. And now, to make things even easier, they can use AMS Server and its Windows C# API (www.aculab.com/support/AMS-Server ). That provides an all-IP, software-only, Windows .NET programming environment for building IVR applications very quickly and cost effectively (sample apps provided). And users can try it out for free via the hosted AMS Server (contact Aculab for a log-in permission).

    While I agree about using HMP and SIP/VoIP licenses, but that is not an option in India till now. VoIP is not allowed to be connected to PSTN network in India.

    I think I would try out AMS server soon, it looks interesting.

    Hi, it is a common misconception that you can’t use Sangoma with Windows. Sangoma does work with Windows — you can use FreeSwitch (which as the name implies is FREE) and simply do scripting. This means, for Rs. 17,000 you have a 1E1 card, manufactured in Canada not China, with a lifetime warranty, Freeswitch, and a toolkit to script with. Its all free. And, you can use a simple PC type machine instead of a server class machine, this will save you money as well. 🙂

    The real issue is how all these compare in cost per line after taking into account all hardware and software costs…:
    – gateway
    – card
    – PC or server of appropriate specification)
    – software (asterisk / freeswitch or whatever…)
    – hosting / office space / power /
    – maintenance – staff etc
    – set up and configuration

    Based on this one might be better off having redundant channels / cards and going for Sangoma and PC’s rather than ApplianX……

    Views much appreciated!
