Transport level l.jpg
Transport Level all

  • Each Multimedia environment needs its own transport standards for the media streams.

  • Available now for:

    • IP for ITU-T H.323

    • IP for IETF SIP, also used in 3GPP Mobile IP Multimedia

    • Circuit switched in H.324 and in 3G.324

    • ISDN in H.320

    • Mobile voice channel – CTM modem in 3GPP

    • Text telephony

  • Gatewaying is also specified in ITU-T H.248 Annex F
