A method and arrangement for enabling multimedia during an ongoing circuit-switched call between a first mobile terminal and a second terminal, wherein the first terminal uses a first access having constraints by not admitting simultaneous packet-switched and circuit-switched communication. A change of connection is detected from the first access to a second access having no such constraints by admitting simultaneous packet-switched and circuit-switched communication. A capability query is then sent to the second terminal in response to said detection. When the requested capabilities are received from the second terminal, possible multimedia applications and/or services are indicated to the user according to the received capabilities.
