Hi, All! I am faced with error in one SIP realization and try to fix it. I am need to know what right behavior in that situation. Client call B2BUA, server answer and must redirect to another location. Server send REFER and for some reason send BYE after REFER and finish dialog.
1. Can UAS send BYE right after REFER sent? 2. If that happens what reply must be sent for 401 Unauth, received in response to REFER? This is current message flow: 192.168.1.120 192.168.1.1 | | 1 : |U------------INVITE----------->| 2 : |<------100 Trying/INVITE------U| 3 : |<--------200 OK/INVITE--------U| 4 : |U-------------ACK------------->| 5 : |U------------INVITE----------->| 6 : |<------100 Trying/INVITE------U| 7 : |<--------200 OK/INVITE--------U| 8 : |U-------------ACK------------->| 9 : |U--------audio/PCMA(8)-------->| 10: |<------------REFER------------U| 11: |<-------------BYE-------------U| 12: |U-----401 Unauthorized/REFER-->| 13: |U-----401 Unauthorized/BYE---->| 14: |<-------------BYE-------------U| 15: |U----------200 OK/BYE--------->| 16: |<------------REFER------------U| 17: |U-----401 Unauthorized/REFER-->| 18: |<------------REFER------------U| 19: |U-----401 Unauthorized/REFER-->| 20: |<------------REFER------------U| 21: |U-----401 Unauthorized/REFER-->| 22: |<------------REFER------------U| 23: |U-----401 Unauthorized/REFER-->| 24: |<------------REFER------------U| 25: |U-----401 Unauthorized/REFER-->| 26: |<------------REFER------------U| 27: |U-----401 Unauthorized/REFER-->| -- Best regards, Igor Goncharovsky _______________________________________________ Sip-implementors mailing list [email protected] https://lists.cs.columbia.edu/cucslists/listinfo/sip-implementors
