I'm also interested in this. I haven't yet tried, but common internet<br>
lore seems to say modems can't work over VoIP, due to the codec /<br>
compression. I know that some people use fax over VoIP, so I think it<br>
must be possible with the right codec and modem speed.<br>
<br>
If anyone else is knowledgeable about dialtone services and modems<br>
over VoIP, please chime in!<br>
