NOTE:
To maximize voice quality using IP Solutions, you must consider both your hardware and network configurations. For example, with IP Softphones, you can send the audio over traditional circuit switch lines, providing high quality voice, or over IP using LAN connections. When making calls over the LAN, voice quality will vary and may be unacceptable if you don’t tune your computers and data network. For example, systems without full duplex audio cards and switch Ethernet ports are not recommended and will provide poor audio quality.
In addition, IP call capacities currently do not match those of traditional switch lines. See Chapter 4 in the DEFINITY ECS R8.2 System Description for more inofmration on call performance.
IP Solutions supports two trunk configurations and three types of softphones. It uses a new IP Interface circuit pack inside the DEFINITY ECS. This IP Interface is new with Release 8. It can operate in either of the following two modes:
■IP
NOTE:
IP Trunk is the default mode for the Release 8 IP Interface only because it may also be used to replace the IP Interface in Release 7 systems. In a Release 8 system, however, the Release 8 IP Interface should be used in MedPro mode.
■
DEFINITY ECS supports multiple Release 8 IP Interfaces operating in a mixture of these two modes or a combination of Release 7 IP Interfaces (operating in the IP Trunk mode) and Release 8 IP Interfaces (operating in either mode). However, a Release 7 or Release 8 IP Interface operating in IP Trunk mode cannot communicate with a Release 8 IP Interface operating in MedPro mode.
Trunks
IP Solutions supports the following two types of trunks.
H.323
The Release 8 IP Interface in MedPro mode enables H.323 trunk service using IP connectivity between two DEFINITY ECS systems. The H.323 trunk groups can be
