Hi all, I need a help to solve some problems in the clearance of a function to perform a query Mysql....I created a function based on documentation of asipto / kamailio devel which is very good... But as I did not want to create a new module I'm trying to use the module domain... whose goal a proxy SIP receive msg that will should validate the realm comparing with a table set up in MySQL(trusdomain)... it should be used into config file to to declare of the table created in the Mysql: modparam ( "domain", "trusdomain_table," trusdomain) the version table of the openser has updated with the creation of this new table (trusdomain) and created a function into file: domain.c / h and a part was need be exported to config file in domain_mod.c / h....but on the tests a call..this proxy kills the pid openser ...
