9.2 Layer 3 (ToS) Priority Control
The router-supported ToS controls routing priority of packets by following the ToS field. You can give
priority to the voice packet using the ToS field.
There are two types of ToS formats: DiffServ and IP Precedence. Before programming the router,
make sure to check which type is supported by the router.

SECTION 10 IP TELEPHONE REGISTRATION AND DELETION

The ports are allocated in blocks of two.
For example:
• Insert a VoIPDB.
• Program 11-02-01 Extension Numbering.
• Configure a System IP Phone and connect to the LAN.
