I hope that Digium would include this otr similar option in the source code. Alternatively, a new option can be created in sip.conf. I am offering no money for this patch. I think all the community needs this to survive the attack of the evil men from shadowlands.
Another nice patch that I already wrote partially, is for cdr_addons_mysql, but it should be included in all cdr-collecting technologies. I just do not save to the database any call that is not connected. This is NOT the same as setting the option at the cdr.conf level. Each cdr technology needs this option as well. I need to save all calls to my cdr_odbc, for ASR calculations, but it is useless to store un-connected calls to mysql, because I use it only as a backup cdr, in case my external SQL Server blows up or has a problem, which happens often. What I did was to hard code this option in the source code, but not including any checkin for a cdr_sql.conf, since I am not a C programmer.
