Ask HN: Would you use a webconference service without telephone?

Hi,

We are brainstorming an idea which is a variation of existing web conferencing solution. We are finding it hard to "implement dialing in via telephone" feature as we lack experience in this field. Is anybody here attends or hosts web conference without telephone(using computer mic and speaker, i.e., VOIP)? Or do you know companies which are interested in this kind of solution for lesser price?

Thanks -- pkc
