Avaya SEND NN feature available in softphone (CANVAS/DAVINCI) for SAP C4 CTI

The Avaya Send NN feature, configured under a button, gives the call center agent the ability to change its caller id, to show to the person he/she is calling, to another number than its personal number. This is required for agents that support fi. multiple brand related customer phone numbers. The agents have with Send NN the ability to identify themselves as calling from the number linked with the customer number for that particular brand. In Avaya One X agent softphone this is working fine, but we have no function/button in Canvas/Davinci that can be used to have the same functionality. This blocking an agent to use the AMC Technology softphone.
