Abstract
A method performed by a gateway node for enhancing a call session between a first User Equipment, UE, and a second UE in a communications network is provided. The second UE is associated to a Private Branch Exchange, PBX, node. When a call session has been established between the first UE and the second UE via the PBX node and via an Internet Protocol Multimedia Subsystem, IMS, network, the gateway node receives, from any one out of the first UE and the second UE, a request for establishing a data channel to enhance the call session. The gateway node negotiates one or more parameters to be used in the requested data channel between the first UE and the second UE. The gateway node establishes the data channel according to the negotiation, to enhance the call session between the first UE and the second UE.
