47 • 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 7 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 381) and call routing (see chapter 40, “Call router configuration” on page 456).

Next, configure the voice over IP settings as needed based on the previous description. First we create the VoIP profile with the needed configurations.
