One of the major problem faced by any IVR developer using analog CTI board is “Detecting Disconnect” after call is hung up by IVR caller. With different disconnect tones used by different PBX manufacturer does not help either.

Detecting Call End or Disconnect is very easy while using digital CTI board with digital interfacing like ISDN, SS7 etc., but detecting DISCONNECT is not that straight forward or easy while using analog CTI boards. It is mainly because of exchanging “control information” with analog technologies!

There are few techniques or information using which DISCONNECT event can be detected and Call End process can be initiated in any CTI application:-

IVR ( Interactive Voice Response) system has many usage in different industries for different purpose,and IVR can also be used for any kind of “registration process” across industries! One may find it interesting, IVR for complaint management is also part of a larger “registration process”!

IVR for registration process

IVR Registration

There are requirement of prior registration for various events like seminar, exhibition, events, presentation. IVR provides simple registration process where any willing participants has to just dial one telephone number, press one key and he is registered! IVR can detect caller ID as the phone number of the caller and with increasing use of mobile phone, phone number is almost as unique as any identity!

Hosted IVR

IVR (Interactive Voice Response) System is solution that perform specific tasks related to presenting, sharing gathering information of a company with its customers or any one over phone. With fast development of internet, IVR systems too have moved from on-premise system to hosted service.

How it evolved

Like any other computer software, IVR has evolved from standalone application to highly networked application with many intelligence as per industry where it is being used. For example, a typical voice portal application fetches data from many different servers located at various geographical locations. The main CTI server is normally located at telecom service provider while all contents, MIS etc are contactly updated, monitored from office of the voice portal operators, all using internet as backbone.

Caller Ring Back Tone or CRBT has become major revenue earner for both teleom companies as well as value added service providers. Not to mention, music companies. Though, I personally prefer the “good old” ring back tone to the latest music number, but many people have been using it on their cell phone, or even land line numbers.

Occasionally, I keep getting mails about how CRBT can be implemented, recently one guy mailed me specifically, “could we implement CRBT locally in our PABX installed in our office ?”, It got me thinking, and I thought I would share my thinking here. Yes, anyone can implement CRBT or caller ring back tone ( Color Ring Back Tone is also used by some, specifically in Dialogic Application Notes) in their PABX system as long as it has digital interface for CTI boards. Technically, that is. Be careful with music copyright though!

But, in a way, CRBT was always present in PBX system in the form of HOLD music during transferring a call, call parking, call on hold ( in a limited way of course)! The same hold music was converted to CRBT which became very successful in terms of hype and revenue.

IVR Menu System

Like any other computer software, IVR too work inputs of responses provided by the user. Though, a computer application software has widely used input devices like keyboard, mouse, voice, even hand movement, IVR applications have limited, only two types of inputs or responses. One is telephone keypad which has 12 keys and automatic speech recognition!

Another specific difference between a normal computer application software and a IVR software is, IVR can provide the options sequentially in voice while computer application software can software options in various menus, buttons, drop down menu, quick links using related graphics etc. So IVR provides its options or tasks it can perform to a caller in series of voice announcement along with key option to press or word, phrase to speak for choosing the tasks. This is known as IVR menu.

With advent of hosted IVR services, IVR application has become designing of this menu system only, while the integration of CTI hardware with various PBX systems have become standard modules provided by hosted IVR service provider.

What is Click To Call ?
“Click To Call” normally refers to a website feature where an website visitor asks to talk to webmaster or website representative ( may be even call center) by entering his phone number. So, this Click to Call facility in a website mainly involves establishing a call between a website visitor and a representative or customer service agent. It may involve monitoring of website visitors in real time and dialing the phone number entered by the visitor manually. But using an IVR ( Interactive Voice Response), this process can be automated as well as many intelligence could be put to use!

There are many benefits of having Click To Call feature in an website in its contact us page or any page where a website visitor may need any further assistance ( for example, in e-commerce website while checking out, restaurant site for reservation enquiry etc.). Click to Call facility may reduce call waiting time for both the visitor and website representative as they are called/connected when both are free to talk on phone.

I keep getting mails by various people about detecting caller id using D4PCI and Dialogic API. I remember I too had to try hard once and finally contacted Dialogic support for getting ideas how caller ID could be detected using D4/PCI analog CTI board from Dialogic. I think the same procedure should work for Donjin Analog boards as well as any kind of Analog CTI boards, for that matter.

So the steps for detecting Caller ID in D4PCI board is :

1. As soon as you detect RINGING, do not connect or answer the call. But start detecting digit using appropriate API function. For example dx_getdig();

2. Important part is the settings in DV_TPT structure which is used in dx_getdig() function. Here is how I have been configuring:
