[SIPForum-discussion] Cseq value for bye

[Karthik Ramiya]

Hi,

  It doesn't matter even if the terminating party terminates the call with Cseq 1 becoz 'BYE' is going to be first request that the terminating party going to initiate. So it can have any non-negative integer value for Cseq(so it can be 1 or 2 etc). But if the originating party wants to terminate the call with 'BYE' , this is going to be the second request that it initiates and obviously Cseq should get incremented in that case.

Cheers,
Karthik

Hi,
But if request for bye comes from terminating side.Then is it necessary that Cseq value must be greater than the previous Cseq of invite which is from originating side.

Hi,

"cseq should be increased for every new request".
Bye is request sent to terminate session so cseq should be a greater value than in Invite(Previous Request.)
