Zones
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 its Peers. See the section
Neighboring the Local VCS to a Cluster for
more information.
SIP port
Species 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 congured on the neighbor system
as its SIP TCP, SIP TLS or SIP UDP port
(depending on which SIP transport mode is in
use).
H.323 port
Species 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 congured on the neighbor system
as its H.323 UDP port. If the neighbor
is another VCS, this will be the port found
under VCS Conguration > Protocols > H.323
in the Registration UDP Port eld.
Conguring Neighbor Zones
SIP mode
Determines whether SIP calls will be allowed to
and from the neighbor zone.
H.323 mode
Determines whether H.323 calls will be allowed
to and from the neighbor zone.
SIP transport
Determines which transport type will be used
for SIP calls to and from the neighbor zone.
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 zone. The
default is Off.
Off: a SIP OPTION message will be sent to the zone.
On: searches will be responded to automatically, without being
forwarded to the zone.
!
This option should normally be left as the default Off.
However, some systems such as Microsoft OCS 2007 will not
accept SIP OPTION messages, so for these zones this should
be set to On. If you do change this to On, you must also congure
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.
Refer to the relevant TANDBERG VCS Deployment Guide for full
details on how to congure these advanced options for specic
systems.
Empty INVITE allowed
Determines whether the VCS will generate a SIP INVITE message
with no SDP to send to this zone. 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-congured 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.
