Outbound Caller ID showing "Unknown" with Flowroute

[JeffsTikiBar]

I have a CName with Flowroute and my 3CX settings for the Outbound Parameters, From are...
From : Display Name = "LineNumber" external number of line
From : User Part = "OutboundCallerId" Outbound caller Id taken from Extension settings in management console
From : Host Part = "GWHostPort" gateway/provider host/port

It may be that what you are sending is unacceptable, and the number is therefor blocked, by your provider. You can confirm, in the 3CX Activity Log (Verbose), what you actually send and then contact your provider to see if they can tell you why the number and name don't pass through.

Did you modify the Flowroute call display options from their default?

Have you tried the default settings provided in the Flowroute template? If you haven't used the default template then I would recommend following the Flowroute configuration guide and set the trunk up that way.
