ISDN is a common dial-up transmission path for videoconferencing.

ISDN is a digital transmission option that uses existing copper telephone lines to carry multiple channels at once. Because it can bundle two 64 kbps B channels (and uses a signaling D channel), it delivers substantially higher and steadier bandwidth than ordinary dial-up modems, which makes videoconferencing feasible over a dial-up path. It is not restricted to fiber-optic only services, nor limited to voice, nor confined to wireless use. These features is what made ISDN a common choice for videoconferencing in earlier networking setups.
