Description
Default
Applicable to
SIP poison mode
On
: SIP requests sent to systems located via this zone are "poisoned" such that if they are received by this VCS again they will be rejected.
Off
: SIP requests sent out via this zone that are received by this VCS again will not be rejected; they will be processed as normal.

Neighbor zones
Traversal client zones
Traversal server zones
DNS zones
SIP encryption mode
Determines whether or not the VCS allows encrypted SIP calls on this zone.
Auto
: SIP calls are encrypted if a secure SIP transport (TLS) is used.
Off
: SIP calls are never encrypted.
This option should normally be left as the default
Auto
. However, this must be set to
Off
for Microsoft Office Communications Server (OCS)
2007 zones.
Auto
Neighbor zones
SIP SDP attribute line
limit mode
Determines whether requests containing SDP sent out to this zone have the length of
a=fmtp
lines restricted.
On
: the length is truncated to the maximum length specified by the
SIP SDP attribute line limit length
setting.
Off
: the length is not truncated.
The
SIP SDP attribute line limit
option should normally be left as the default of
Off
. However, some systems such as Microsoft OCS 2007
cannot handle attribute lines longer than 130 characters, so it must be set to
On
for connections to these systems.

Neighbor zones
DNS zones
SIP SDP attribute line
limit length
If
SIP SDP attribute line limit mode
is set to
On
, sets the maximum line length of
a=fmtp
SDP lines.
130
Neighbor zones
DNS zones
SIP multipart MIME
strip mode
Controls whether or not multipart MIME stripping is performed on requests from this zone.
This option should normally be left as the default
Off
. However, it must be set to
On
for connections to a Microsoft OCS 2007 Release 2
system.
Off
Neighbor zones
SIP UPDATE strip mode Controls whether or not the VCS strips the UPDATE method from the Allow header of all requests and responses received from this zone.
This option should normally be left as the default
Off
. However, some systems such as Microsoft OCS 2007 do not support the UPDATE
method in the Allow header, so for these zones this should be set to
On
.
Off
Neighbor zones
Interworking SIP search
strategy
Determines how the VCS searches for SIP endpoints when interworking an H.323 call.
Options
: the VCS sends an OPTIONS request.
Info
: the VCS sends an INFO request.
This option should normally be left as the default
Options
. However, some endpoints such as Microsoft Office Communicator (MOC) clients
cannot respond to OPTIONS requests, so this must be set to
Info
for connections to a Microsoft OCS 2007 system.
