Voice Modems

A voice modem offers an economical means of starting a single line telephony system. Voice modems are not supported under Windows NT 4.0.

Although they are an economical solution, voice modems have many limitations which are discussed at length in the section on Limitations of the Software.

When purchasing a voice modem, look for these key features:

• Supports Windows TAPI 1.4-2.1 and has wave drivers.
• Does not have a software-based controller.
• Does not have a USB connection. In all of our tests, USB modems had extremely poor sound quality.

We are often asked for specific modem suggestions. Unfortunately, modem manufacturers are changing models, parts, and drivers continuously. It is impossible to keep pace with the myriad modem manufacturers and provide recommendations based on all the recent changes. Our best suggestion is to buy a modem that has a return policy and test it with the software to see that it performs to your satisfaction.

Some resources to help you select a compatible modem include:

• Our modem test results page compares several brands of voice modems: http://www.activecallcenter.com/modems/modemlist.htm
• Our modem checker utility will give you a preliminary indication of whether or not your modem might work with Active Call Center.
• Search our support forums for recent posts by customers on modems.

If you have problems with installing the voice modem, contact the modem manufacturer or try the suggestions in the section on Troubleshooting General Telephony Hardware Problems.
