From: Paul Kyzivat <[EMAIL PROTECTED]> Its allowable in certain cases, but it can have negative consequences.
The problem is that if the messages get out of order then eventually you end up processing a message with an invalid CSeq. This may be ok if the messages sent later supersede the ones sent earlier. (This is probably the case for REFER.) But if the subsequent messages don't supersede one another you are likely to have trouble. Or maybe we could say that you can send multiple responses before receiving responses for any of them, but you must be prepared for any subset of them to be successful, and the remainder rejected. (Although the requests that are executed will be executed in proper order.) *Sometimes* that is not a problem, but it usually only happens if no request depends on the success of previous requests.
