Caixia, I do not think specification missed anything. This is quite intentional. There is no limit of how long the caller can be dialing the number (as there is no limit on how long the caller can stay connected on a SIP call). If you need to put a limit on this duration, this will have to be application specific and does not need to be defined in the SIP spec. For instance you can define that dial timeout when placing the call is 1 minute and that will limit the duration of the proceeding state. Or you can set the dial timeout at 10 minutes. Or you can set this to be unlimited and let the caller hang up when they are done waiting for the call to connect. This is really up to you. The same way you can put maximum call duration at 24 hours and limit calls this way or you can let the caller hang up when they are done talking. _____________ Roman Shpount
