Hi there! I found solution about marking packets. In sip.conf I put ... tos_sip=cs5 tos_audio=ef tos_video=af41 ... But when I test the packets with wireshark, the sip qos is set at 0x22 with AF=41 Is the tos should be forever set at tos_sip=cs3? Anyone could help me please? -------------- next part -------------- An HTML attachment was scrubbed...
