CRIN: Least Cost Routing
jtendo CRIN is IN platform for wholesale traffic which performs intelligent carrier routing based on static and dynamic criteria:
- retrieved from the routing request (INAP/SIP parameters)
- statically configured (direct routing, traffic distribution, time and date based, etc.)
- data imported via batch interface (in-/outbound price lists)
- calculated dynamically on runtime (quality, capacity, volume, etc.)
Common Use Cases
- CRIN selects the most profitable outgoing Carrier from predefined ones on the basis of imported price-lists (calculates margins on the basis of buying and selling prices)
- CRIN uses overflow control mechanism to make sure calls are connected even if the most desirable outgoing Carrier is unavailable (e.g. returning errors)
- CRIN detects and blocks fraudulent traffic on the basis of automatic blacklisting feature
- CRIN makes sure agreed commitments (like number of minutes connected via specific Carrier) are fulfilled
- CRIN helps fulfilling governmental regulations by partitioning the traffic (e.g. EEA/rest)
Routing Features
Rules can leverage the following engine features:
- call-by-call routing
- extraction of INAP/SIP parameters
- traffic screening
- parameters addition/replacement
- regular expressions evaluation
- multiple routes for overflow routing (the number of routes is not limited)
- traffic distribution with a ratio
- rerouting on the basis of returned Cause Value
- price based routing
- time and date based routing
- KPIs based routing (internal and imported from external sources)
- capacity/volume based traffic distribution
