Configuration manual

Name Range or Default Description
that the user agent may
switch to any of those codecs
during the session without
further negotiation. The
system does not support
multiple concurrent codecs
for a session, so loss of
speech path will occur if the
codec is changed during the
session. If codec lockdown is
enabled, when the system
receives an SDP answer with
more than one codec from
the list of offered codecs, it
sends an extra re-INVITE
using just a single codec from
the list and resubmits a new
SDP offer with just the single
chosen codec.
Avaya Aura
®
Session Manager line redundancy
In an Avaya Aura
®
network that includes multiple Avaya Aura
®
Session Managers for
redundancy, the B5800 Branch Gateway system can be configured with a secondary Avaya
Aura
®
Session Manager line. If for any reason the B5800 Branch Gateway system's primary
Avaya Aura
®
Session Manager line goes out of service, the system will automatically attempt
to use the secondary Avaya Aura
®
Session Manager line. Prioritization of the Session Manager
lines is determined by the line number configured for a particular Session Manager line. For
example, if the first Session Manager line is configured with line number 17 and the second
Session Manager line is configured with line number 18, then line number 17 has the higher
priority and is considered the primary Session Manager line. If for some reason you want to
designate the secondary Session Manager line as the primary line, you must change one or
both of the line numbers associated with the Session Manager lines so that the secondary
Session Manager line number is lower than that of the primary line.
The redundancy operation of the Session Manager lines is based on line prioritization. The
active line to which B5800 Branch Gateway sends all calls is always the highest priority Session
Manager line in service. If the primary Session Manager line is in service, it is the active line
for sending calls. If the connection to the primary Session Manager line is lost, causing B5800
Branch Gateway to switch to the secondary Session Manager line, when the primary line
comes back up, B5800 Branch Gateway will switch back to the primary B5800 Branch Gateway
line.
If all available channels of the current Avaya Aura
®
Session Manager line are in use, the B5800
Branch Gateway will not overflow calls to the other Avaya Aura
®
Session Manager line.
