Section: 5.3.6.6 vSRVCC handover to a circuit-switched multimedia call
Content: Upon vSRVCC handover to a traffic channel suitable for a data call, the MS shall use a single bearer capability IE for multimedia with ITC set to "UDI" and FNUR set to 64 kbit/s for the call. NOTE: After the MS has attached the user connection (see subclause 5.2.4.3), the MS initially uses predefined codecs for voice and video as specified in 3GPP TS 26.111[ Codec for circuit switched multimedia telephony service; Modifications to H.324 ]  [80]. Additionally, the MS can perform in-band codec re-negotiation using H.245 signalling according to the procedures defined in 3GPP TS 26.111[ Codec for circuit switched multimedia telephony service; Modifications to H.324 ]  [80].
