Scroll Prev Up Next More

IP Office is a converged telephony system. That is, it combines aspects of traditional PABX telephone systems and digital IP data and telephony systems.

The VoIP mode of operation can include external SIP trunks, IP trunks between customer systems and/or H.323 or SIP IP telephones for users. In either case the following factors must be considered:

The IP Office control unit must be fitted with voice compression channels. These are used whenever an IP device (trunk or extension) needs to communicate with a non-IP device (trunk or extension) or to a device that uses a different codec.

A network assessment is a mandatory requirement for all systems using VoIP. For support issues with VoIP, Avaya may request access to the network assessment results and may refuse support if those are not available or satisfactory.

 

A network assessment would include a determination of the following:

A network audit to review existing equipment and evaluate its capabilities, including its ability to meet both current and planned voice and data needs.

A determination of network objectives, including the dominant traffic type, choice of technologies, and setting voice quality objectives.

The assessment should leave you confident that the implemented network will have the capacity for the foreseen data and voice traffic, and can support H.323, DHCP, TFTP and jitter buffers in H.323 applications.

An outline of the expected network assessment targets is:
