[SR-Users] execute only on INITIAL INVITE

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!
