IP Solutions
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 Trunk—used for IP trunk connections. This is the default mode for the Release 8
IP Interface, and this mode makes it compatible with Release 7 systems.
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.
■ MedPro—used for H.323 trunk connections and H.323 voice processing for IP
softphones. This mode requires the new C-LAN circuit pack.
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
