The user Outbound caller ID is a number, usually the DID number of the extension. You can set a name of the user in the extension settings. Some SIP devices can also hold a name, which can be sent in some cases.Thank tou for explain. It mean add name as in User for field Outbound Caller ID or in SIP trunk configuration as also to field Outbound Caller ID.
That can vary, depending on the provider. Best to confirm with them.But the public operator must confirm, where he will expect the name.
These parameters will determine which name/number will be sent, and taken from where. Again, check with your provider, they can tell you where they expect the information.After is also necessary make the configuration in SIP trunk Outbound parameters.
