From: "Hagai Sela \(TA\)" <[EMAIL PROTECTED]> I have a subscribe / notify based DTMF relay mechanism, in which I am the UAC (I send SUBSCRIBE). I have the following situation: I send an outbound SUBSCRIBE, and it receives 200 OK with an "expires" value. I then re-subscribe when that time has elapsed, and then I get some error code. Now I get NOTIFY, which I shouldn't get because the subscription request has failed. Which response code should I return for this NOTIFY request?
You should get a NOTIFY right at the end of the subscription, informing you that the subscription is ended. I suppose this might arrive slightly after the scheduled end of the subscription. Of course, you should re-SUBSCRIBE well before the end of the subscription time. If you receive a NOTIFY for a subscription that has just expired, you should probably respond with 481 (meaning, subscription does not exist), although 200 seems plausible as well.
