Hi, it RFC 4342, section 5.3 (Packet Sizes), it says that CCID-3 is not appropriate for applications that require a fixed interval of time between packets and vary their packet size instead of their packet rate in response to congestion. The question is: in this case it is not recommended to use VBR codecs such as SPEEX on the application layer? Is this same issue occurs in the CCID-4? Leandro. -- Leandro Melo de Sales.
