Figure 9-18 84-10: ToS Setup
To set the IP Precedence/Diffserv bits for packets leaving the IP terminal there are the following two
options:
• System wide. If all IP phones use the same ToS value, this can be assigned in commands
84-23-06 and 84-23-12. When an IP phone registers with the CPU, it looks for settings in these
commands. If these are found, they override any previous individual settings.
• Individual. If different IP phones require different ToS assignments, due to the network
configuration, these assignments must be set at each individual station
Command 84-23 requires a Hexadecimal representation of the 8 bit ToS field. For example, to assign
the signaling packets an IP precedence value of 4 and the voice packets an IP precedence value of 5,
it would be as follows. Refer to
Figure 9-19 SIP MLT Basic Setup on page 9-24 .
• 80 in Hex is 10000000 - This represents the signaling packets leaving the IP phone
• A0 in Hex is 10100000 - This represents the voice packets leaving the IP phone
