Does the older x00 series and the newer x10 series MultiVOIP support Diffserv?

The newer series MultiVOIP, (i.e. 210, 410, 810, 2400, 2410, 3010) support Diffserv.

The older series MultiVOIP, (i.e. 110, 120, 200, 200a, 400, 800) only support the Diffserv feature when the VOIP is using H.323.

Our TOS bit is set to 0x40 in hex or in binary 0100 0000.
