Soft dialers

A soft predictive dialer uses software equipped with ISDN or CTI capabilities to provide analysis of calls made. A software-based predictive dialer generally is relatively cheap, as it doesn’t require expensive telephony components. Typically a soft predictive dialer is connected to a PBX using a CTI link. It requires specialized call classification cards to perform call progress analysis and answering machine detection.

ISDN allows a switch to filter out all non productive calls. It can provide digital code indicating the type of non-connect. In this manner all non-connects are eliminated and the right reason codes are transmitted to the software application. Agents don’t have to listen to special tones to detect whether call is busy or un-obtainable.

In cases like detecting answering machines (AMD) and integrating with other voice related functions (IVR, voice recording, speech recognition, text-to-speech etc.) a soft dialer may not offer as many features as one that is hardware-based.

The advantages of Soft Dialers compared with Hard Dialers are:

• Low cost; Soft Dialers do not require expensive telephony components.

• Flexibility; Soft Dialers work well in multi-site and distributed environments.

Soft Dialers have the following disadvantages:

• Some older PBXs will not work with a soft dialer configuration.

• The error rates in classification of calls are higher; fax, modem, etc. have to be detected by the agent.

• Call-processing capacity is lower.
