Network restrictions are not applied for OCS call as described in the NTP

PROBLEM TEXT:
Network restrictions are not applied for OCS call as described in the NTP.

NTP NN43001-121 "Converged Office Fundamentals" says:
"The Network Class of Service (NCOS) setting for outgoing calls from Office Communicator clients is determined by the configuration of the MARP TN when in a MADN group, or by the configuration of the UEXT when it is the only TN for the user."

However, in reality with MADN configuration, the restrictions on MARP TN do not affect the call from OC client.

SETUP AND ACTIONS PERFORMED TO CAUSE THE PROBLEM:
Converged Office with OCS 2007 R2.
User A1 DN 2000- 2004p2 phone
User A2 DN 2000- UEXT TLSV

User A1 (MARP):
TGAR 1
NCOS 2
CLS TLD

User A2:
TGAR 0
NCOS 0
CLS UNR

PRI trunks emulating PSTN. Network restrictions are configured to block outgoing PSTN call with NCOS 2.

1. Make a call from OC client to PRI trunk (PSTN).

EXPECTED RESULTS:
1. Call is blocked as per NTP (restrictions are taken from MARP TN).

ACTUAL RESULTS:
1. Call goes through.

Solution : Design team has created a fix patch MPLR33327. This needs to be installed.
