In order to display a Caller ID from the initial caller, a user has to navigate to ‘Tenant' → 'Extensions' → the 'Caller ID' section and set the options as follows:
- Trust Remote-Party-ID: ‘Yes’
- Send Remote-Party-ID: ‘Use Remote-Party-ID’
NOTE: If a call is being transferred outside of PBXware (an outbound call), these options need to be set on the Trunk level as well.
Further, a user should log into the phone’s GUI and set the following option:
- Caller ID Source: 'RPID-PAI-FROM'
For example, if using Yealink, the following option can be found when navigating to 'Account' → 'Advanced' → 'Caller ID Source'.
For more information, please refer to the screenshot.
NOTE: These settings need to be set on all Extensions included in the call flow.
