Routing

<p>In this example, assuming the default tariff table is set to <span class="reference">BT</span>BT,
then any call data from the site <span class="reference">Default Site</span> 'Default Site' would be reinforced as a BT call.</p>

<p>If, however, a call was made using the trunk access code <span class="keyword">78</span>, it would be costed as a <span class="reference">PrivateWire</span> call.</p>

<p>This would be overridden if the call was made over any of the trunks 2001
to 2007.  In this case it would be costed at <span class="reference">NTL</span> NTL rates.</p>

<p>However, taking precedence above all of this, if the call was made from any of the
extensions 3000 to 3003, it would be priced using the <span class="reference">Payphone</span> Payphone rate.</p>
