I can pretty easily see creating a script to cache the results and only check before calling a new number. Also, grn/ezcall logs can be harvested - after the fact.</div>
<div><br></div><div>With both of these together - is it possible to group together to maintain a list, automatically? e.g. the script that looks up will also submit to one of our DBs. There's local caching, coding issue, conflict resolution, cache age, and infrastructure which makes this not a simple project...</div>
