Do all dialup modem chipsets support voice telephony?
When you say “voice telephony”, are you referring to VOIP? If so, read on. If not, politely ignore my answer 🙂 I think your question is orthogonal to VOIP. The modem chipset handles modulation of digital signals into analog signals that travel over the phone lines, only to be remodulated back into digital signals by the other side’s modem. It’s a very low-level connection, in the scheme of things. Now, VOIP rides on top of that low-level connection, encoding and compressing your dynamically recorded voice into digital packets that are transmitted to the receiver. However, these packets are just 1’s and 0’s (digital), transmitted to the modem….which encodes them into an analog signal, and so on. Whether you are transmitting VOIP packets, or a picture, or any other type of file, it doesn’t really matter to the modem; the modem just translates digital bits to an analog waveform for transmission over the the phone lines. This is why I said your question seems orthogonal to VOIP: the mod
