Chapter 13 Voice Over IP (VoIP)

H.323 Connection

VoIP (Voice over IP) allows the system to transmit voice conversations over a corporate Intranet using ITU-T H.323 protocol. For DtermIP-to-DtermIP connection via the IP network with H.323 protocol, the IPT card and IP-PAD card are required to transmit and receive the control signal and voice data. For voice compression, the 16VCT card and 4VCT card are required. For Legacy terminal connection via the IP network with H.323 protocol, the IPT card is required.
