The only way to know for sure is real time LNP dips. What was a
landline an hour ago could become a cell phone in a matter of
seconds.<br>
<br>
The LNP dips will still need a database to look up the returned LRN
in, which is where telcordia's databases (or mine, (shameless plug)
<a class="moz-txt-link-freetext" href="http://www.telcodata.us/">http://www.telcodata.us/</a>) come in.<br>
<br>
You can use telcordia's or mine to do some basic pre-scrubbing of
numbers for basic validity, exclude known wireless ranges (which
COULD be landlines, as you can port wireless numbers to wired as
well! I don't know your application but I thought I'd mention that)
etc.<br>
