YES. In a large scale Farm-of-Asterisks application (thousand+ concurrent calls) where calls with a certain Tier 1 carrier requires 183 for some routes and not for others. Thus an adaptable dial plan and sip.conf. Unfortunately, the consumer should really care because it says a lot about their SIP provider(s) endeavors to provide reliable service - - - if we can adapt our Asterisks to their idiosyncrasies. <RANT> IMHO - - - because of the highly distributed [i.e. fractured-proxy ] design of the supposedly Tier-1 provider network. The carrier needs extra time and assistance to setup the RTP path with the real media port of another-carrier's point of origin. This usually indicates the calls are not organic calls from the carrier's own retail traffic but are 2nd or 3rd route calls collected from diverse wholesale sources [i.e. other carriers] where the RTP is probably not running over the Tier-1's own network. OUR OWN constant push to pass RTP over someone else's network must be controlled. We are deceiving ourselves (and our consumers) if we mistakenly believe that a recognizable Tier-1 brand name is synonymous with good VoIP service. </RANT> ..mike.. ..mike.. _______________________________________________ -- Bandwidth and Colocation Provided by http://www.api-digital.com -- asterisk-users mailing list To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-users
