Configuring WAN interfaces

PPP VoIP configuration

The following figure illustrates a common PPP VoIP configuration between two sites connected
over a WAN:
Figure 22: PPP VoIP configuration over WAN
Site A contains four IP phones and a G350 with S8300 and one MM342 media module. The
MM342 media module connects the G350 to the WAN via a USP 128Kbps V.35 interface. The
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
Note:
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 default RTP UDP port range is 2048 to 3028.
●
Network IPs (24 bit subnet masks):
●
- IP phones - 149.49.54.0 (VLAN 1)
- Data - 11.11.11.0 (VLAN 2)
