A2Billing doesn't do that. A2Billing in fact has a lot of shortcomings one of which is this exact issue.<div><br>I would suggest running rate sheets against each other for finding true LCR and then only uploading the rates that are cheaper into the system. In most cases there are not such high differences but if there are then this is the only way. I know rate normalization talk comes up all the time on FreeSwitch Freenode channel and it probably does on OpenSIPs as well. Check there for some good advice.</div>

</div>How does a2billing do it? It should be pretty easy in an AGI. If you can<br>
afford a linear lookup per call, just grep through the array of prefixes<br>
to find the ones matching a particular call, then pick the cheapest from<br>
the results.<br>
<br>
If you need something faster than linear it gets tricky. It would be<br>
tempting to preprocess the list to say 5 digits, do a hash lookup on<br>
those, and then use the process above.<br>
