VoIP Implementation with a G700 Media Gateway and an S8300 Media Server

In Figure 4.10, Site A contains four IP phones and a data LAN connected via a P333T-PWR switch to a S8300 Media Server. The S8300 Media Server houses a X330W-2USP expansion module that is connected to the WAN via a 128Kbps V.35 interface. Following are the connection details for Site A:

•The IP phones are configured with the following DSCP tagging:

—Voice = DSCP 46

—Voice control = DSCP 34

Note: The Policy list in the next configuration is based on the assumption that the Media Gateway, Media Server, and the IP phones send VoIP control packets with a DSCP value of 34 and voice with a DSCP value of 46. If any of the components of the topology are sending control or voice packets with other DSCP values, you must make changes in the Policy list.

•The S8300 Media Server default RTP UDP port range is 2048 to 3028.

•Network IPs (all 24 mask):

—IP phones - 1.1.1.0 (VLAN 1)

—Data - 11.11.11.0 (VLAN 2)

—Serial - 2.2.2.1

—Gatekeeper - 149.49.54.81

—MGP - 149.49.54.82

—VoIP (MGP) - 149.49.54.83

Site B contains four IP phones and a data LAN connected to a P333T-PWR switch in a stack with a G700 Media Gateway. The G700 Media Gateway houses a X330W-2DS1 expansion module that is connected to the WAN via a two-timeslot (128Kbps) T1 interface. Following are the connection details for Site B:

•IP phone are configured with DSCP tagging:

—Voice = DSCP 46

—Voice control = DSCP 34

•The G700 Media Gateway default RTP UDP port range is 2048 to 3028.

•Network IPs (all 24 mask):

—IP phones - 3.3.3.0 (VLAN 1)

—Data - 33.33.33.0 (VLAN 2)

—Serial - 2.2.2.2

—MGP - 4.4.4.10

—VoIP (MGP) - 4.4.4.11
