Zones Zone [1..1000] Neighbor SIP Poison Mode: <On/Off>
Controls whether SIP requests sent out to this zone will be "poisoned" such that if they are received by the local VCS again they will be
rejected. Default: Off .
On: SIP requests sent out via this zone that are received again by this VCS will be rejected.
Off: SIP requests sent out via this zone that are received by this VCS again will be processed as normal.
Example: xConfiguration Zones Zone 3 Neighbor SIP Poison Mode: Off
Zones Zone [1..1000] Neighbor SIP Port: <1024..65534>
Specifies the port on the neighbor to be used for SIP calls to and from this VCS. Default: 5061 .
Example: xConfiguration Zones Zone 3 Neighbor SIP Port: 5061
Zones Zone [1..1000] Neighbor SIP ProxyRequire Strip List: <S: 0,255>
A comma separated list of option tags to search for and remove from Proxy-Require headers in SIP requests received from this zone.
By default, no option tags are specified.
Example: xConfiguration Zones Zone 3 Neighbor SIP ProxyRequire Strip List:
"com.example.something,com.example.somethingelse"
Zones Zone [1..1000] Neighbor SIP RFC3327 Enabled: <Yes/No>
Controls whether the VCS will insert RFC3327 Path headers when proxying REGISTER messages toward this zone. If disabled the
VCS will instead rewrite the contact header to allow interworking with SIP registrars that do not support RFC3327. Default: Yes.
Example: xConfiguration Zones Zone [1..1000] Neighbor SIP RFC3327 Enabled: Yes
Zones Zone [1..1000] Neighbor SIP Record Route Address Type: <IP/Hostname>
Controls whether the VCS uses its IP address or host name in the record-route or path headers of outgoing SIP requests to this
zone. Note: setting this value to Hostname also requires a valid DNS system host name to be configured on the VCS. Default: IP.
Example: xConfiguration Zones Zone 3 Neighbor SIP Record Route Address Type: IP
Zones Zone [1..1000] Neighbor SIP SDP Attribute Line Limit Length: <80..65535>
If SIP SDP attribute line limit mode is set to On, sets the maximum line length of a=fmtp SDP lines. Default: 130 .
Example: xConfiguration Zones Zone 3 Neighbor SIP SDP Attribute Line Limit Length: 130
Zones Zone [1..1000] Neighbor SIP SDP Attribute Line Limit Mode: <On/Off>
Determines whether requests containing SDP sent out to this zone will have the length of a=fmtp lines restricted. Default: Off .
On: the length will be truncated to the maximum length specified by the SIP SDP attribute line limit length setting.
Off: the length will not be truncated.
Example: xConfiguration Zones Zone 3 Neighbor SIP SDP Attribute Line Limit Mode: Off
Zones Zone [1..1000] Neighbor SIP SearchAutoResponse: <On/Off>
Controls what happens when the VCS receives a SIP search that originated as an H.323 search, destined for this zone. Default: 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.
Example: xConfiguration Zones Zone 3 Neighbor SIP SearchAutoResponse: Off
Zones Zone [1..1000] Neighbor SIP TLS Verify Mode: <On/Off>
Controls X.509 certificate checking and mutual authentication for inbound and outbound connections between this VCS and the
neighbor system. When enabled, the neighbor system's FQDN or IP address, as specified in the Peer address field, must be
contained within the neighbor's X.509 certificate (in either the Subject Common Name or the Subject Alternative Name attributes).
Default: Off .
Example: xConfiguration Zones Zone 3 Neighbor SIP TLS Verify Mode: On
