QoS issue

We are having some difficult trying to mark packets on a Summit 200i.
Configuration is something like:

# Access-mask Configuration
create access-mask TRAF_SIP dest-L4port
create access-mask TRAF_RTP source-L4port
create access-mask TRAF_ATA source-ip/32 precedence 10
create access-mask TRAF_IP source-ip/29 precedence 20
#
# Access-list Configuration
create access-list QOS_SIP TRAF_SIP dest-L4port 5060 permit qosprofile
QP6 set code-point 41
create access-list QOS_RTP TRAF_RTP source-L4port 16384 permit
qosprofile QP6 set code-point 46
create access-list QOS_RTP1 TRAF_RTP source-L4port 16385 permit
qosprofile QP6 set code-point 46

When we set code-point to 46, we correctly see EF on a sniffer, but
code-point 41 that would in theory be AF41, appears as unknown.

Ideas ?

Tks,
Rubens

Rubens,
I believe the code-point decimal value of 41 to be a binary value of
101001, which would would be an unknown Diffserv PHB class.
AF41 should be a binary value of 100010 or a decimal value of 34.
