Called Party May Not Recognize Real-Time Communications Client Program Dialed Digits (307527)
The information in this article applies to:
- Microsoft Windows XP Home Edition
- Microsoft Windows XP Professional
This article was previously published under Q307527 SYMPTOMS
A real-time communications client program that uses in-band Dual Tone MultiFrequency (DTMF) with a G.723.1 codec may have trouble dialing recognizable digits because of poor tone quality.
The problem is more likely to occur during second stage dialing when you makes a computer to telephone call. This is typically required by called party Interactive Voice Response (IVR) units that prompt for digits, such as those used for prepaid calling cards, reservation services, and so on. A series of dialed digits that contain zeros (0) can be particularly vulnerable to distortion.
