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 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 local 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.
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.
Default: Off
Example: xConfiguration Zones Zone 3 Neighbor SIP SDP Attribute Line Limit Mode: Off
Zones Zone [1..1000] Neighbor SIP SearchAutoResponse: <On/Off>
Determines what happens when the VCS receives a SIP search that originated as an H.323 search, destined for
this zone.
Off: a SIP OPTION message will be sent to the zone.
On: searches will be responded to automatically, without being forwarded to the zone.
Default: Off
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
Zones Zone [1..1000] Neighbor SIP Transport: <UDP/TCP/TLS>
