CallManager 3.3.4 - Change AF31 to CS3

I have been unsuccessful in finding the correct service parameter in CM 3.3.4 to change the signalling (for phones, mgcp, and h.323) from af31 to cs3. In CM 4.1 the parameters are there.

Any idears'?

It's called:

"IP TOS BitMask for Comm. Between CCM and Device"

Change 0x68 to 0x60 to convert from AF31 to CS3.

Re: CallManager 3.3.4 - Change AF31 to CS3

Hi,

Dont have a 3.3(4) now but if I remember correctly..

should be Under Enterprise Services menu on the Call Manager.

Find the item marked "DSCP for Cisco Call Manager to Device Interface".

Repeat this for the item marked "DSCP for SCCP Phone Configuration" or "IP TOS BitMask for Comm Between CCM and Device" not sure if those r options will double check tomorrow in lab.

Do you have that options?

For pre CCM 4.0 the value should be 0X68 (AF31), and >= CCM 4.0 0X60 (CS3). The value is changing in order to align Cisco's QOS markings with RFC standards
