Conferencing Voice quality and delay
problems if the party
controlling the conference is
on the IP trunk (voice paths
from external callers come in
on the IP trunk, are
conferenced, then sent out to
other external parties across
an IP trunk) Avoid conference calls where at
least two other parties are on the
other side of the IP trunk.
NOTE:
The following conferences
work OK:
■
Conferences of parties on
the local Avaya Definity
Server
■
Conferences controlled by
the local Avaya Definity
Server, involving local
parties and only 1 party on
the other side of an IP trunk
DCS Know limitations:
■
Auto Callback
Coordinate specific administration
and between the IP trunk and
Avaya MultiVantage Software

limitations on routing flexibility may
apply.
ISDN IP trunking has no signalling
capability. ISDN not supported. This includes:
■
10-digit number display
■

Voice mail Calls that have terminated at
one location and then cover
to a second site for voice mail
coverage can have voice
quality degradation. Centralized voice mail through an
IP network is not recommended.
