Zones Zone [1..1000] Neighbor SIP B2BUA Service Identifier: <0..64>
The identifier that represents an instance of a local SIP Back-to-Back User Agent service.
Example: xConfiguration Zones Zone 3 Neighbor SIP B2BUA Service Identifier: 1
Zones Zone [1..1000] Neighbor SIP ClassFiveResponseLiveness: <Yes/No>
Specifies whether Class 5 SIP responses from neighbor peers result in the zone being considered alive for use. Default: Yes.
Example: xConfiguration Zones Zone 3 Neighbor SIP ClassFiveResponseLiveness: Yes
Zones Zone [1..1000] Neighbor SIP Duo Video Filter Mode: <On/Off>
Determines whether INVITE requests sent to this zone filter out Duo Video. This option may be required to enable interoperability
with SIP devices that do not support Duo Video. Default: Off.
On: the second video line in any outgoing INVITE request is removed.
Off: INVITE requests are not modified.
Example: xConfiguration Zones Zone 3 Neighbor SIP Duo Video Filter Mode: Off
Zones Zone [1..1000] Neighbor SIP Encryption Mode: <Auto/Microsoft/Off>
Determines how the VCS handles encrypted SIP calls on this zone. Default: Auto.
Auto: SIP calls are encrypted if a secure SIP transport (TLS) is used.
Microsoft: SIP calls are encrypted using MS-SRTP.
Off: SIP calls are never encrypted.
Example: xConfiguration Zones Zone 3 Neighbor SIP Encryption Mode: Auto
Zones Zone [1..1000] Neighbor SIP MIME Strip Mode: <On/Off>
Controls whether multipart MIME stripping is performed on requests from this zone. This must be set to On for connections to a
Microsoft Office Communications Server 2007. Default: Off .
Example: xConfiguration Zones Zone 3 Neighbor SIP MIME Strip Mode: Off
Zones Zone [1..1000] Neighbor SIP Media Encryption Mode: <Off/On/BestEffort/Auto>
The media encryption policy applied by the VCS for SIP calls (including interworked calls) to and from this zone. Default: Auto
On: All media must be encrypted.
Off: All media must be unencrypted.
BestEffort: Use encryption if available otherwise fallback to unencrypted media.
Auto: No media encryption policy is applied.
Example: xConfiguration Zones Zone 3 Neighbor SIP Media Encryption Mode: Auto
Zones Zone [1..1000] Neighbor SIP MediaRouting Mode: <Auto/Signaled/Latching>
How the VCS handles media for calls to and from this neighbor, and where it will forward the media destined for this neighbor.
Default: Auto. .
Signaled: media is always taken for calls to and from this neighbor. It will be forwarded as signaled in the SDP received from this
neighbor.
Latching: media is always taken for calls to and from this neighbor. It will be forwarded to the IP address and port from which media
from this neighbor is received.
Auto: media is only taken if the call is a traversal call. If this neighbor is behind a NAT the VCS will forward the media to the IP address
and port from which media from this zone is received (latching). Otherwise it will forward the media to the IP address and port
signaled in the SDP (signaled).
Example: xConfiguration Zones Zone 3 Neighbor SIP MediaRouting Mode: Auto
