Does anyone know of any programs for Win '98 that can be used to encode/decode speech through the computer's sound card, and communicate with Asterisk running on a Linux box on the network? Trying to avoid the 3rd-party "soft-phone" route, and integrate something a little more seamless into our proprietary app to place calls through Asterisk from a Win '98 machine (either open-source or utilizing command-line dial / hangup, etc. parameters).
P.S. examples of things I've been looking at, and are not sure of their compatibility/usability w/ Asterisk are OpenH323's "OhPhone", Speex, LinPhone, etc.
