#### Description <!-- Describe your changes in detail --> Previous version did not allow deletion of all rows in the table although this is allowed as described in section [9.2.9](http://www.asipto.com/pub/kamailio-devel-guide/#c09f_delete) of the Kamailio SIP Server v3.2.0 Development Guide. Former code always assumed filters would be involved so this change skips the filter matching if no filter is applied. You can view, comment on, or merge this pull request online at:
