If you receive a _retransmission_ of a 200 OK, you must send the same ACK you sent to the original transmission you received. If you receive a 200 OK from a different branch, you need to generate a new ACK for that 200 OK. You cannot use the ACK you kept for the first 200 OK. > > Regards, > > Indresh K Singh > > _______________________________________________ > Sip-implementors mailing list > [email protected] > https://lists.cs.columbia.edu/cucslists/listinfo/sip-implementors _______________________________________________ Sip-implementors mailing list [email protected] https://lists.cs.columbia.edu/cucslists/listinfo/sip-implementors
