home Asterisk used for >1 yr, running on small Ubuntu machine, works great.
Destination-based routing used to route outgoing calls between 3 service providers (also works fine).
Recently changed ISP and now an new interesting issue arises: an even more efficient form of routing would be something like:
for national landline numbers, use provider X
for national mobile numbers, use provider Y
for international numbers, use provider Z for the first 200 minutes of calls per month, but if >200 minutes used provider Y
Is it possible to do this with Asterisk? It does not immediately appear to be possible but this might just be my lack of knowledge.
(I use FreePBX as a GUI frontend)
