In this scenario, a dial plan rule is used to replace the source SIP extensions with a unique SIP extension that will be displayed to the recipients. This rule can be used to ensure the privacy of the callers.
Scenario
- What do you want to do? Display a unique source SIP extension for any call that is made.
- What you need to do before defining the rule? Select the SIP extension that will always be used as the source. In this scenario, 123456 is the selected SIP extension.
- How can you do it? You need to create a rule that takes any call from Sipelia™ Server and replace the source SIP extension with 123456.
