Test Purpose {
TP Id TP_ISC_SCCAS_MED_BYE_01
// When the transfer of a session is successfully completed, then the SCC AS shall release the source legs as follows:
// 1) the source access leg is an ongoing session containing only an active or inactive media component or a session in
// an early dialog phase on the terminating side, send a SIP BYE request on the source access leg in accordance
// with 3GPP TS 24.229 [2];
Test objective "Verify that the SCC AS sends a SIP BYE after transfer of a session is successfully completed and the source access leg is an ongoing session containing only an active or inactive media component"
