  • Page 17: Overview Of Voice Over Ip (Voip)

    Overview of Voice over IP The 4600 Series IP Telephones allow enterprises to use Voice over IP (that is, packet-switched networks) instead of telephony over the Public Switched Telephone Network (PSTN). However, the use of data networks for transmitting voice packets poses the problem that data networks were not designed for the specific qualities required by voice traffic.

  • Page 18: Delay And Jitter

    (for example, for interactive transactions), data requirements tend to be not as strict as most voice requirements. Release 1.1 of the 4600 Series IP Telephones incudes a dynamic jitter buffer. This feature automatically smooths jitter to improve audio quality.

  • Page 19: Voice Coding Standards

    Overview of Voice over IP (VoIP) Voice Coding Standards There are a number of voice coding standards. The Avaya 4600 Series IP Telephones offer the options described below. G.711, which describes the 64 kbps PCM voice coding technique. G.711-encoded voice is already in the correct format for digital voice delivery in the public phone network or through PBXs.

    MIB termed MIB-II. In addition, devices may define one or more "custom MIBs" that contain information about the specifics of the device. Release 1.1 of the 4600 Series IP Telephones is fully compatible with SNMPv2c (a later version of SNMP) and with Structure of Management Information Version 2 (SMIv2), although the telephones will respond correctly to queries from entities that comply with earlier versions of SNMP, such as SNMPv1.

  • Page 21: Network Assessment

    It is assumed that your organization has performed a network assessment (with or without the assistance of Avaya) before attempting to install Voice over IP, in order to have a high degree of confidence that the existing data network has the capacity to carry voice packet traffic and is compatible with the required technology.

    4600 Series IP Telephone LAN Administrator’s Guide The 4600 Series IP Telephones support both IEEE 802.1D/Q and DiffServ, and may in the future support other, possibly proprietary, procedures for implementing Quality of Service. In addition, other network-based QoS initiatives such as UDP port selection do not require support by the telephones, but nonetheless can contribute to improved QoS for the entire network.

  • Page 51: Diffserv

    To support DiffServ, the 4600 Series IP Telephones can be administered either from the network, via appropriate administration of the DHCP or TFTP servers, or at the telephone itself, via dialpad input.

  • Page 52: Udp Port Selection

    To support UDP port selection, the 4600 Series IP Telephones can be administered either from the network, via appropriate administration of the DHCP or TFTP servers, or at the telephone itself, via dialpad input.
