description There is herein disclosed a method performed by a terminal device, such as a user equipment, comprising including, in the terminal device, a list of circuit switched capabilities of the terminal device, sending, from the terminal device, the list to a network device during an attachment procedure of the terminal device to a packet-switched only network, wherein the list comprises a codec list of codecs supported by the terminal device, wherein the codec list is suitable for use at the network device in a Single Radio Voice Call Continuity, SR-VCC, handover procedure of the terminal device comprising a handover signaling initiation with a target circuit-switched network and a voice bearer split from other packet switched bearers, wherein the network device comprises a mobility management entity.
