Description
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)
Know limitations:
Auto Callback
IP trunking has no signalling
capability.
Calls that have terminated at
one location and then cover
to a second site for voice mail
coverage can have voice
quality degradation.
Recommendation
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
Coordinate specific administration
and between the IP trunk and
Avaya MultiVantage Software
for any DCS functionality. Some
limitations on routing flexibility may
apply.
ISDN not supported. This includes:
10-digit number display
QSIG
Path replacement
Centralized voice mail through an
IP network is not recommended.
