VTS should work with any standard voice modem. However, our developers have tested the following modems under XP, Vista and Windows 7 with no issues.
- Multi-Tech MT5634ZPX-PCI-U
This model is no longer in production. However, they are the easiest to work with if you can find them. - Multi-Tech MT9234ZPX-UPCI
This is the latest model. Ensure that the model number does not contain ‘NV’ (no voice). Zoom 3095, Mini USB Modem (Good voice modem but does not work with pagers.)
- AOPEN Fm56
For Windows XP only. The drivers are not supported in Vista or Windows 7.
Voice Modem Installation and Removal Guide
Due to the non-standard ways in which different brands of voice modem interact with Windows Operating Systems, we have created a guide to help developers select, install and replace these devices.
Note: These procedures are for those with high-level skills in VTS and Windows operating systems. Proper modem installation and configuration can be difficult and time consuming. If you experience difficulties, contact our Technical Support team right away. (1.855.887.2232)
