46 • VoIP profile configuration
Examples
Different applications require different VoIP profiles. This section includes a variety of applications and show
how the VoIP profile for these applications would be configured.
Home office in an enterprise network
Figure 85 is an example of a home office in an enterprise network. The connection bandwidth is 128 kbps and
is of very low quality, so the low bit-rate G.723_6k3 codec is used. Likewise, silence suppression is enabled.
Because of the low bit-rate codec, DTMF relay is also enabled. As 80 to 100 ms jitter is anticipated, the dejitter
buffer is set to adaptive with a maximum delay of 100 ms.

First, configure the required CS interfaces (see chapter 33, “CS interface configuration” on page 373) and call
routing (see chapter 40, “Call router configuration” on page 445).
Next, configure the voice over IP settings as needed based on the previous description. First we create the VoIP
profile with the needed configurations.
