Hi Martin,
I would say you check your Trunk Settings, and create a specific outbound trunk where you can change this.
In the below screenshot, the outbound call will use the call-source, which in the case would be customer ANI, but if you move the "This Trunk" setting up the order and then provide a trunk level phone number, it uses that phone number.
It may not work in all scenarios as your other business needs may require to use the queue specific phone number.
