### Description Incoming Invite triggers CCR toward OCS. In CCA with Result-Code DIAMETER_SUCCESS (2001) missing Result-Code in Multiple-Services-Credit-Control AVP. Kamailio handles this successful charging transaction as a failure in the following lines: if (ro_cca_data->mscc->resultcode != 2001) { LM_DBG("CCA failure at MSCC level with resultcode [%d]\n", ro_cca_data->mscc->resultcode); error_code = RO_RETURN_FALSE; goto error1; } The resultcode is mandatory in this statement, so if Multiple-Services-Credit-Control AVP does not contain Result-Code which is optional according to RFC 4006 the charging transaction is considered as failed. #### Reproduction To reproduce the issue the diameter CCA should look as following: Diameter Protocol Version: 0x01 Length: 392 Flags: 0x40, Proxyable Command Code: 272 Credit-Control ApplicationId: Diameter Credit Control Application (4) Hop-by-Hop Identifier: 0x66ea324d End-to-End Identifier: 0x8777d597 [Request In: 2623] [Response Time: 0.457246000 seconds] AVP: Session-Id(263) l=52 f=-M- val=ar.voice-pre-5.domain.int;843835511;1 **AVP: Result-Code(268) l=12 f=-M- val=DIAMETER_SUCCESS (2001)** AVP: Auth-Application-Id(258) l=12 f=-M- val=Diameter Credit Control Application (4) AVP: CC-Request-Type(416) l=12 f=-M- val=INITIAL_REQUEST (1) AVP: CC-Request-Number(415) l=12 f=-M- val=0 AVP: CC-Session-Failover(418) l=12 f=-M- val=FAILOVER_NOT_SUPPORTED (0) AVP: Unknown(12018) l=45 f=VM- vnd=12239 val=31363239386664653539382d303030303465363864343333...
