30.9 Examples
30.9.1 Branch Offices in an Enterprise Network
Figure 30-2 shows a branch office in Linn and a branch office in Zurich connected to the main office
in Berne over ISoIP. Zurich and Berne are linked over an 2 MBit/s direct copper DSL wire and use
the voice codec G.711 for this high-rate connection. The local office in Linn is linked to Berne over an
500 KBit/s leased line and therefore uses the low-bit-rate voice codec G.723.

First we create the CS interfaces and configure the call routing (without Session Router). We need
two ISoIP interfaces because we have two different voice codecs from the branch offices.
