Remote Gateway 911x Series Installation and Administration Guide
Check the Quality of Service (QoS)
configuration on the RLC. Adjust the
configuration, if required.
Lower the QoS threshold so that
transition occurs earlier.
Analyze the traffic patterns on your
voice and IP networks as described in
the Remote Gateway 9100 Series
Network Engineering Guidelines (NTP
555-8421-103). (This NTP is available
from your Nortel distributor.) It is
possible that your IP network capacity
cannot accommodate the additional
voice data, especially during High Day
Busy Hour (HDBH) periods. Make
adjustments to your network as
required.
Ensure your telephone is not on call
forward.
Ensure that the Remote Gateway 911x
series unit is not in offline mode by
entering the online SPRE code at a
digital telephone.
Ensure that the Remote Gateway 911x
series unit is powered up. It cannot
receive calls from the host PBX if it is
not powered up.
Ask the network administrator to ensure
that the RLC is correctly configured with
your Remote Gateway 911x series unit's
IP address, telephone number, and
security ID (if they are used).
