Modems Compatible With Ascendis Caller ID

Unfortunately, the sheer number of modems available prevents us from being able to track general compatibility. However, there are some modems that are known to work successfully with Ascendis Caller ID. These are listed below.

In theory any modem with Type I caller id support and proper Windows drivers should work. In practice, it's often difficult to determine whether a given modem includes Type I caller id support. In addition, many modems with Type I caller id support do not include caller id support in their drivers. Sometimes a new driver can be downloaded from the modem manufacturer. Note that modems that claim support for Type II caller id, call waiting id, or off hook caller id will not work with Ascendis Caller ID unless they also include Type I caller id support. Many modems include Type II caller id support but not Type I, because Type II is cheaper.

To further complicate matters, many modems respond affirmatively to commands to enable caller id, even though they don't actually support it. We recommend buying your modem from a store that allows exchanges or returns without a restocking fee so you can return it if it doesn't work as expected.

Recommendations

In general, we prefer hardware controller-based modems over winmodems or softmodems. While winmodems are cheaper, they require more computer resources and are prone to the same software compatibility issues as all programs and drivers on your computer.

Zoom 3049C (External Serial Modem)
We have tested and recommend the Zoom external serial modem, model 3049C.  This is an external modem that requires a serial port to connect to the computer.  External modems are easier to install than internal modems, and they usually provide status lights, as does this one.

The "C" at the end of the model number indicates a Conexant chipset.  When purchasing this modem, look for the "C", or the extended model number "3049-00-00C" to ensure you get the right model.  Other models with other chipsets may perform differently.

This modem is supposed to support caller id in the following countries and regions: Austria, Canada, China, Denmark, Finland, France, Germany, Hong Kong, India, Japan, Singapore, Taiwan, U.K., and U.S.A. (Source: Zoom technical support, January 25, 2005)  However, Ascendis Software has only tested this modem in the US and has not received confirmations of successful use in any other country.  Two UK users (one with phone service from BT) could not get it to report caller information.

Details on this modem can be found on Zoom's web site.

Internal PCI Modem -- no recommendation at this time
At this time we do not have a recommendation for an internal modem. The models we've had consistent success with are old, and not currently sold. We hope to be able to recommend one in the future.

You may be able to find one of the models listed below.

  • "This modem can be picked up for around USD 11, and all I did was shut down the machine, plug it in, WinXP found the modem and installed the drivers automatically. I opened your program and walla, it just works. I'm very impressed."
  • http://www.trendnet.com/products/TFM-PCIV92I.htm
  • Note: Be sure to get the one with the "I" at the end of the model number. They also sell one without the "I" that does not include caller id support. TFM-PCIV92I is good, TFM-PCIV92 is not.
  • This modem reports Private and Out of Area calls incorrectly in Australia, and possibly other non-US locations. In the US, it appears to work fine. (7/05/2004)
  • No longer available (5/14/2005)

Multiple Modems

If you intend to put multiple modems in a single computer for multi-line support, you should be aware of potential problems, especially with software-based modems. Please see our forum postings on this topic.
