A method performed by a network node, for handling an outgoing media call of a user associated with multiple User Equipment, UEs, in a communications network is provided. The network node receives (402) a request for the outgoing media call to be set up from a first UE out of the multiple UEs. The request is obtained as a voice instruction 5 from the user via a Digital Assistant, DA, device. The voice instruction comprises a personalized name associated with the first UE. The network node further identifies (403) among the multiple UEs, the first UE and its associated IP Multimedia Subsystem, IMS, identifier based on the personalized name received in the voice instruction. The network node further sends (404), to an IMS node, the identified IMS identifier of the first UE and a 10 request to whether or not the first UE is registered in the IMS node and supports media of the outgoing media call. When the first UE is registered in the IMS node and supports the media of the outgoing media call, the network node initiates (405) the outgoing media call from the first UE. When the first UE is not registered in the IMS node and/or does not support the media of the outgoing media call, the network node decides (406) how to 15 proceed with the outgoing media call.
