Automatically reconnect to ODBC sources?

view story

http://serverfault.com – I am using Asterisk and a MySQL database connected via ODBC to store CDRs. When my MySQL database isn't available when Asterisk starts or has an outage while Asterisk is running, I would expect Asterisk to retry to connect to the database, but this doesn't happen! Anyone knows where I can enable some kidn of automatic reconnect to databases in Asterisk? My res_odbc.conf looks like this: [asterisk] enabled => yes dsn => asterisk-connector username => root password => yetalive pre-connect => yes pooling => no limit => 1 idlecheck => 1 negative_connection_cache (HowTos)
