SIP RTP TOS bits 184 in TCLASS field

Hello all,
I have a production server which I just upgrade from v.1.8 to 11, where the ToS I have it configured as:

[quote]tos_sip=cs3
tos_audio=ef
cos_sip=3
cos_audio=5[/quote]

But in the console I see that the using of the SIP ToS is failing, as:

[quote] == Using SIP RTP TOS bits 184
== Using SIP RTP TOS bits 184 in TCLASS field.
== Using SIP RTP CoS mark 3[/quote]

I’m trying to figure out how can I calculate the appropiated tos for my network, but no idea how to do it… could any of you share info. how to to it, please, as I could’nt find clear info googling…

Thanks in advance;)
