26.11 Example
26.11.1 Home Office in an Enterprise Network
Figure 26-8 is an example of a home office in an enterprise network. The connection bandwith
amounts to 128 kbit/s 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, therefor 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.
