Number Determination Sources
This section of the configuration enables the definition of prioritized lists of trusted devices, from which phone number information may be taken for the caller and callee, along with the headers to be used (for example, From/To).
Note:
Only data leaving a device via the Trusted IP ranges is considered for number determination purposes.
