-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 What we do is the following:
Our CPE (Customer premises equipment) registers via IAX with all of our servers at the same time (with qualify turned on for the links). All of the servers first try to reach numbers via local IAX links. If this fails they do a DUNDi lookup to the other servers to check if they are able to terminate the call. With regards to PSTN connectivity each server has a collection of methods to terminate the call with ISDN failover. Every minute each of the VoIP links are checked and their results stored in the routing table. Routes that are not accessible are temporarily removed till their responses improve. A destination is the selected based on: 1) Availability 2) Weight 3) Price The choice is made in the above order. Some providers are not very good at terminating some destinations even though the connection to them might be fine. We use this to decide on the weight. Better quality termination gets a higher weight. We then take the destinations with the highest weight (100 if the route is fine). If there are multiple destinations with the same price in this group, we chose the cheaper one. In all of the CPE the calls failover to the other servers if they are unavailable (the qualify setting does this). So, as long as there are no calls on a particular box, you can just stop Asterisk and do whatever you like. Each server updates all other server's MySQL database for credit when they are available. If not, a replication conflict email is sent so that I can manually tally any problem credits. If I thought about this properly I could probably make this automatic. - -- Kind Regards, Matt Riddell Director _______________________________________________ http://www.venturevoip.com (Great new VoIP end to end solution) http://www.venturevoip.com/news.php (Daily Asterisk News - html) http://feeds.venturevoip.com/AsteriskNews (Daily Asterisk News - rss) -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.7 (MingW32) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org iD8DBQFHAc0KDQNt8rg0Kp4RAn5xAJ41jLnhml3HRXj7O86ZJVPZNd2j7ACgjWXm ERH/Gj4r6j06c0LOC0/8VPQ= =QzBV -----END PGP SIGNATURE----- _______________________________________________ --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
