Configuring neighbor zones
The following options are available (in addition to the
common
zone options
) when configuring a neighbor zone on the VCS.
Neighbor zones are used to enable a connection from the local
VCS to a neighbor system.
!
Systems that are configured as Alternates (peers) must
not also be configured as neighbors to each other, and
vice versa.
Protocol
SIP mode
Determines whether SIP calls will be allowed to and from the
neighbor system.
SIP port
Specifies the port on the neighbor system to be used for SIP calls
from the local VCS.
This must be the same port number as that configured on
the neighbor system as its SIP TCP, SIP TLS or SIP UDP
port (depending on which
SIP transport
mode is in use).
SIP transport
Determines which transport type will be used for SIP calls to and
from the neighbor system.
H.323 mode
Determines whether H.323 calls will be allowed to and from the
neighbor system.
H.323 port
Specifies the port on the neighbor system to be used for H.323
calls from the local VCS.
This must be the same port number as that configured on
the neighbor system as its H.323 UDP port. If the
neighbor is another VCS, this will be the port found under
VCS configuration > Protocols > H.323
in the
Registration UDP
Port
field.
Location
Peer 1 to Peer 6 address
The IP address or FQDN of the neighbor system. If the neighbor
is a VCS cluster, this includes all of the peers in the cluster. See
the section
Neighboring the local VCS to another VCS cluster
for
more information.
Advanced
Zone profile
Determines the configuration of the
Advanced
settings for this
zone. The options are:
Default
: the VCS will use the default values for these settings.
Microsoft Office Communications Server 2007
: the VCS will
automatically select the configuration settings required for
connections to a Microsoft OCS 2007 server. Refer to the
relevant TANDBERG VCS Deployment Guide at
http://www.
tandberg.com/support/documentation.php
full details on how to
configure the VCS and OCS to enable the two systems to work
together.
Custom
: enables you to configure each Advanced setting
individually.
!
Do not use the
Custom
option or configure the individual
Advanced
settings except on the advice of TANDBERG
customer support.
The default is
Default
.
Searches are automatically responded to
Determines what happens when the VCS receives a SIP search
that originated as an H.323 search, destined for this neighbor.
The default is
Off
.
Off
: a SIP OPTION or SIP INFO message (depending on the
Interworking SIP strategy
setting) will be sent to the neighbor.
On
: searches will be responded to automatically, without being
forwarded to the neighbor.
!
This option should normally be left as the default
Off
.
However, some systems such as Microsoft Office
Communications Server (OCS) 2007 will not accept SIP
OPTION or SIP INFO messages, so for these zones this should be
set to
On
. If you do change this to
On
, you must also configure
pattern matches to ensure that only those searches that actually
match endpoints in this zone are responded to. If you do not, the
search will not continue to other lower-priority zones, and the call
will be forwarded to this zone even if it cannot support it.
Empty INVITE allowed
Determines whether the VCS will generate a SIP INVITE message
with no SDP to send to this neighbor. INVITES with no SDP
mean that the destination device is asked to initiate the codec
selection, and are used when the call has been interworked
locally from H.323. The default is
On
.
On
: SIP INVITEs with no SDP will be generated and sent to this
neighbor.
Off
: SIP INVITEs will be generated and a pre-configured SDP will
be inserted before the INVITEs are sent to this neighbor.
!
In most cases this option should normally be left as the
default
On
. However, some systems such as Microsoft
OCS 2007 will not accept invites with no SDP, so for
these zones this should be set to
Off
.
The settings for the pre-configured SDP are configurable
using the
xConfiguration Zones Zone [1..200]
Neighbor Interworking SI
P
commands. They
should only be changed on the advice of TANDBERG customer
support.
