Hi all Tcpdump shows Kphone UDP traffic has not set as minimum delay traffic! This is a tcpdump from My-IP to Other-IP: 13:07:14.704501 IP (tos 0x0, ttl 64, id 813, offset 0, flags [DF], proto: UDP (17), length: 120) My-IP.32784 > Other-IP.10384: UDP, length 92 0x0000: 4500 0078 032d 4000 4011 0fce db4a 37e4 0x0010: d5ba 3e91 8010 2890 0064 50f7 8008 032e 0x0020: ff63 f69f 0a00 0000 d4d4 d4d4 d4d4 d4d4 0x0030: d4d5 d5d5 Here TOS is 0x0, that is, normal traffic! Are VoIP clients supposed to set TOS to minimum delay? Is there any reason for this? Or is this something developers over looked? Many thanks in advance.
