Example

Home office in an enterprise network
Figure 81 is an example of a home office in an enterprise network. The connection bandwidth amounts to 128
kbps and is very low quality. Therefore low-bit-rate codec G.723_5k3 is used which is only supported on
ISoIP. Likewise silence compression is also enabled. Because of the low-bit-rate codec dtmf relay is enabled. 80
to 100 ms jitter is expected, therefore the dejitter buffer is set to adaptive with a maximum delay of 100 ms.
Because the wire causes a high alternation of the voice signal, voice volume gain has to be set to 20 dB.

First we configure the required CS interfaces and call routing. In this chapter we focus on configuring VoIP
profiles, therefore we have omitted the configuration of the CS interfaces and call routing.
Next we configure the voice over IP settings as needed from the description above. First we create the VoIP
profile with the needed configurations.
