Hi Spencer, the carrierroute module is also actively maintained, mtree as well. The drouting is available but probably the one with the least usage here. Its initial import has been done from Raul Alexis and I guess they use it in production, but don't know details. There were also some patches from other people in the last year, but recently it has seen not that much activity. 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 Best regards, Henning _______________________________________________ SIP Express Router (SER) and Kamailio (OpenSER) - sr-users mailing list sr-users@lists.sip-router.org http://lists.sip-router.org/cgi-bin/mailman/listinfo/sr-users
