Hi all, I need to setup an inbound DID router for 8 proxies and ~300 DID's. Very simple, a call comes in from pstn> kamailio looks up DID for exact match in mysql> returns location> If db result returns noservice redirect to 1.2.3.4 else remain in call-flow and send to destination. Having a failure route capability would be nice. From what I've read on each of the 4 modules, any could do what I need though each have their own complexities. I'm still new to kamailio and hoping to utilize the group here for some advice. I'd like to keep this as simple as possible then adding/deleting DID's from the db as needed for routing. In your experience which would be the best module to use in order to achieve my goal?

The modules differ mostly in their provided configuration interface, their capabilities and the internal used datastructures IMHO. lcr * introduced in 0.9.x times, reworked several times * provided initially support for a limited number of routes, today it supports large route sets as well * provides easy failover functionaly to try sequentially several gateways * uses internally a hash table cr * introduced in 1.3, reworked for 1.5 * support larger route sets * provides flexible failure routing capabilities with a dedicated table, but is more complicated to setup and use * uses a trie (tree) internally mtree * introduced in 3.1 * support larger route sets * provides generic tree matching functionality, but without that much additional functionality * uses a tree internally drouting * ported from opensips for 3.0 * support larger route sets * provides failover capabilities and some special matching as time or date * uses a trie (tree) internally
