Hello David, First of all your checking for a to-tag is correct. In-dialog requests should have a to-tag, and therefore the block you pasted here won't execute at all for those. If you're worrying about provisional (1xx) replies sent from the UAS for the initial INVITE, then indeed some of them might also not have a to-tag set. However, if the code block you pasted is in the request_route() "main" route, then it won't be executed anyway. For responses to be specially processed via the configuration script, you either have to have a reply_route() set, or an onreply_route() set if you're doing stateful processing with the tm module.

Yes, the presence of a To tag differentiates in-dialog requests from initial ones. -- Alex On Mar 20, 2018, at 8:03 PM, David Villasmil <david.villasmil.work@gmail. com> wrote: Hello guys, I want to execute an sql only for INITIAL INVITEs, I'm trying like: #!ifdef WITH_DID_VALIDATE if(!has_totag()) { sql_query("acd", "select * from did_numbers where didNumber = '$tU' and active = 'Y'", "ra"); xlog("L_ERR", "[REQUEST_ROUTE] number of rows in table domain: $dbr(ra=>rows)\n"); if( $dbr(ra=>rows)==0 ) { xlog("L_ERR", "[REQUEST_ROUTE] DID Number validation returned [$dbr(ra=>rows)], not responding to this request\n"); exit; } sql_result_free("ra"); } #!endif But, say I remove the DID from the allowed list while a call is going on. Then responses to the allowed INVITE would not be processed. How would I limit that to ONLY the INITIAL INVITE? Should I use has_totag? Thanks!
