Hi, i am making a small android application which VoIP program based
in SIP(Session Initiation Protocol). Through this program, i will
support the QoS for each service such as voice telephony, SMS
messaging and so on. So, i want to mark the TOS field(8bit) in IP
packet header to grant priority each service IP packets.

As you know, there is a method "setTrafficClass(int value)" in android
UDP socket API. But, after capturing the packets using the wireshark,
i could found that this API is not effect. In short, the UDP socket
always sends packets with default IP TOS field, 0x00.

Does anybody know why this problem case?
Does android prohibit chaging IP header process on purpose?

Plz, give me some advice about this problem.
