Sniffer not showing dscp value of call setup packets

[summerdike]

When setting up a call using voice over ip, the ELU32 board is involved, so Application system parameters 227 en 228 apply.

I set 228 to 30 (class 3, diffserv for tcp packets) and 227 to value 29 (EF, diffserv for udp packets).

I use Ethereal (packet sniffer) to check if the right dscp values are used in the packets, but they are not.
The right values ARE used when two extensions are connected (voice, UDP) but not during call setup (TCP packets, H.225 & H.245).

Has anyone the right values for DSCP in TCP packets?

(System is BC12sp6. Revision status ELU32 hardware is R6A, software is R4F).

When connecting all devices to a hub the dscp values are the ones I configured.

So it is the switch that disturbs the configuration.
