Hi, I have a scenario here in the lab :
eMTA P-CSCF Invite--------------------> <----------------------------180 <---------------------------200OK ACK----------------------------> BYE------------------------------> <--------------------------------407 BYE-----------------------------> <---------------------------------200OK BYE---------------------------------> <------------------------------------200OK In this scenario the second BYE ( after 407 ) gets the 200OK but after 500ms and therefore sends the third BYE ( retransmission ). 1) The CSeq in second and third BYEs are same ( CSeq: 3 BYE ). Is this correct? 2) The P-CSCF after its gets the 3rd BYE ( retransmission ), sends the 200OK back. Shouldn't it send 4xx saying that no transaction exist? I am thinking since P-CSCF has already sent 200OK for 2nd BYE, it has terminated the transaction and Dialog on its side. So any retransmissions of BYE from UAC should be responded back with 4xx. Thanks, Vivek. _______________________________________________ Sip-implementors mailing list [email protected] https://lists.cs.columbia.edu/cucslists/listinfo/sip-implementors
