Outbound Site-Code Dialing Example
To illustrate an outbound site code dialing call flow, consider the topology presented in
Figure 7-27 and its corresponding configuration in Example 7-32.

Following are the specific steps that are involved in this example:
1. Phone2-1 in Austin dials 801-2001 (that is, it places a call to San Jose Phone1-1). The
incoming called number, or DNIS, is 801-2001 and the calling number, or ANI, is
2001. The called number matches two dial peers: 8010 and 8011. Dial peer 8011 is
matched because it has the best preference, and the translation-profile outgoing
intersite-out command is applied because this is an outbound call. Thus, the call is
routed to San Jose with DNIS 8012001 and ANI 8022001.
2. If the WAN fails, the call will be routed using dial-peer 8011 with preference 1 configured.
The translation-profile 801 PSTN is used, which modifies the DNIS to
14085552001 (that is, the call can be routed by the PSTN to San Jose). Note that the
ANI is modified using the global voice translation profiles configured on the voice
port, which are used for all PSTN calls.

Note In addition to the digit manipulation used for site-code dialing, global voice translation
profiles configured on the voice port are used.
