It really is only widely accepted as defined for IP networks only.

While I have heard only positive things about both Junction Networks and Teliax, if you have the volume traffic and do not need their value added services, why don't you go directly with one of the Tier 1 carriers?<br><br>Would cost you definitely less... <br><br>Moshe<br></tt></div></blockquote></div><br></div></body></html>
