A method and apparatus for including media content in a session invite procedure for a push to talk type service in a radio communication network. Client A sends an invitation to Client B inviting Client B to establish a push to talk type session. The invitation includes a representation of the media content, smaller than the media content itself. The representation may be a compressed or reduced-size or reduced-resolution version of the media content or an extract thereof. The representation is displayed or played to the Client B user, who decides whether to accept the invitation. The invitation may be a Session Initiation Protocol (SIP) Invite message, and the service may be a push to talk over cellular (PoC) service.
