Zones Zone [1..1000] TraversalServer SIP Protocol: <Assent/TURN/ICE>
Determines which firewall traversal protocol will be used for SIP calls to and from the traversal client. Note:
the same protocol must be set on the client for calls to and from this traversal server.
Default: Assent
Example: xConfiguration Zones Zone 1 TraversalServer SIP Protocol: Assent
Zones Zone [1..1000] TraversalServer SIP TLS Verify Mode: <On/Off>
Controls X.509 certificate checking and mutual authentication between this VCS and the traversal client. If
enabled, a TLS verify subject name must be specified.
Default: Off
Example: xConfiguration Zones Zone 5 TraversalServer SIP TLS Verify Mode: On
Zones Zone [1..1000] TraversalServer SIP TLS Verify Subject Name: <S: 0,128>
The certificate holder's name to look for in the traversal client's X.509 certificate (must be in either the Subject
Common Name or the Subject Alternative Name attributes).
Example: xConfiguration Zones Zone 5 TraversalServer SIP TLS Verify Subject Name:
"myclientname"
Zones Zone [1..1000] TraversalServer SIP Transport: <TCP/TLS>
Determines which of the two transport types will be used for SIP calls between the traversal client and VCS.
Default: TLS
Example: xConfiguration Zones Zone 5 TraversalServer SIP Transport: TLS
Zones Zone [1..1000] TraversalServer TCPProbe KeepAliveInterval: <1..65534>
Sets the interval (in seconds) with which the traversal client will send a TCP probe to the VCS once a call is
established, in order to keep the firewall's NAT bindings open.
Default: 20
Example: xConfiguration Zones Zone 5 TraversalServer TCPProbe KeepAliveInterval: 20
Zones Zone [1..1000] TraversalServer TCPProbe RetryCount: <1..65534>
Sets the number of times the traversal client will attempt to send a TCP probe to the VCS.
Default: 5
Example: xConfiguration Zones Zone 5 TraversalServer TCPProbe RetryCount: 5
Zones Zone [1..1000] TraversalServer TCPProbe RetryInterval: <1..65534>
Sets the frequency (in seconds ) with which the traversal client will send a TCP probe to the VCS.
Default: 2
Example: xConfiguration Zones Zone 5 TraversalServer TCPProbe RetryInterval: 2
Zones Zone [1..1000] TraversalServer UDPProbe KeepAliveInterval: <1..65534>
Sets the interval (in seconds) with which the traversal client will send a UDP probe to the VCS once a call is
established, in order to keep the firewall's NAT bindings open.
Default: 20
Example: xConfiguration Zones Zone 5 TraversalServer UDPProbe KeepAliveInterval: 20
