Re: [Sip-implementors] Re-Invite & Bye - on the wire

hi,

now why has it been proposed that a UA shouldn't worry about the response for a BYE?

Hi,

I think it's valid for a node, after it has sent a BYE (even if the transaction is still pending), to send 481 Call/Transaction does not exist if it receives any messages for that session, becuase from the node's point of view the session is most
likely already terminated (even if the specific BYE transaction is still pending). I would assume (of course I can't confirm this) most nodes really don't care what response they get to a BYE anyway...
