Info

title	Note:

Make sure when configuring sipSigPort and dsbcSigPort for an S-SBC deployment that you specify different IP addresses for them. To do so you must select different metavariables for each of them. The actual values of the metavariables are determined during orchestration based on your Heat templates.

Zone SIP Signaling Port Parameters

Div

class	pdf8pttext

0	Table
1	Zone SIP Signaling Port Parameters

Parameter	Length/Range	Description


`<index #>`	1-4096	The Sip Signaling Port for this zone.	M
`action`	N/A	Use this object to specify a clearing action when the SIP Signaling Port goes out-of-service (OOS). Calls can be forcefully cleared or allowed to dry up in out-of-service mode. `dryup` – SBC starts the `dryUpTimeout` timer indicating the time in minutes the calls are allowed to complete. Once the timer expires, ongoing calls are torn down gracefully. `force` (default) – Ongoing calls on the given signaling port are cleared immediately.	O
`dryUpTimeout`	1-1440	Use this parameter to specify the duration (in minutes) during which existing calls are allowed to complete in out-of-service mode. (range: 1-1440 / default = 60) When `action` = `dryup` and `sipSigPort` goes OOS, the SBC starts a dry-up timer for the configured duration to allow existing calls to complete in OOS mode. The SBC exhibits the following behavior when the dry-up mode is enabled: Calls: All in-dialog messages are allowed, new INVITE messages are rejected with 503. Registrations: All refresh REGISTER and de-REGISTER messages are allowed, new REGISTER messages are rejected with 503. Out-Of-Dialog (OOD) relay messages: All new OOD messages are rejected with 503. However, in-dialog messages with-in REFER and SUBSCRIBE dialogs are allowed. Once the `dryUpTimout` timer expires, the SBC tears down ongoing calls and all ongoing SIP Registrations and non-call related dialogs are cleared internally. The SIP Signaling Port is then moved to OOS state whereby SIP messages are no longer admitted. NOTE: This parameter is only visible when `action` = `dryup`. NOTE: This parameter is configurable irrespective of the setting of the SIP Signaling Port state.	O
`dscpValue`	0-63	DSCP value for packets from this SIP Signaling Port. (default = 0).	O
`enforceAORMatch`	N/A	Enable this flag to enforce AOR matching for messages from registered users. `disabled` (default) `enabled`	O
`facState`	N/A	Use this flag to control whether the fault avalanche control state uses the global level setting. `disabled` - The system does not check for blocking or dropped packets that this signaling port received. `system` (default) - The signaling port inherits the global level setting.


`ipAddressV4`	N/A	IPv4 address for this SIP signaling port in dotted decimal format (for example 128.127.50.224). NOTE: For S-SBC configurations, this parameter is replaced with the parameters in the S-SBC Parameter Differences table below.	O
`ipAddressV6`	N/A	IPv6 address for this SIP signaling port in hexadecimal/colon format. (for example, 1280:1276:3350:2224:2222:3333:8888:1245 or fd00:21:445:128::7880). NOTE: For S-SBC configurations, this parameter is replaced with the parameters in the S-SBC Parameter Differences table below.	O
`ipInterfaceGroupName`	1-23 characters	The name of the IP Interface Group used by this signaling port.	M
`maskIpAddressforRcb`	N/A	Use this flag to fetch the RCB value for a user using only the source port and not the source IP address for generating the hashKey. `disabled` (default) `enabled` NOTE: The flag `maskPortforRcb` must be disabled to use this flag. Both flags cannot be enabled at the same time.	O
`maskPortforRcb`	N/A	Use this flag to fetch the RCB value for a user using only the source IP address and not the source port for generating hashKey `disabled` (default) `enabled` NOTE: The flag `maskIpAddressforRcb` must be disabled to use this flag. Both flags cannot be enabled at the same time.	O
`mode`	N/A	Operational mode for this SIP Signaling Port. `inService` (default) `outOfService`	O
`portNumber`	1-65535	UDP/TCP port number of SIP Signaling Port (default = 5060). If `transportProtocolsAllowed` is “`sip-udp`”, ensure that `portNumber` value is outside the configured system-wide `mediaPortRange` unless `portNumber` = default value “5060”. If `portNumber` is set to a number other than “5060”, the user is prompted to continue with the configuration. For example, if media port range is 5000-6000, `portNumber` should be configured starting with 6002 (6001 cannot be used as its used for RTCP by default). To view `mediaPortRange` values, use the command: `> show configuration details system media mediaPortRange`	O
`recorder`	N/A	Enable flag to indicate the port is being used for recording. `disabled` (default) `enabled`	O
`sctpProfileName`	1-23 characters	SCTP profile name.	O
`siprec`	N/A	Administrative state of the SIP Signaling Recorder Port. Enable flag to use the port for recording using SIPREC Protocol. `disabled` (default) `enabled` NOTE: The SIPREC feature is controlled by a system-wide SBC license (SBC-SIPREC). If the license is not available, any SIPREC recording returned by a PSX is ignored. NOTE: When the siprec flag is enabled, ensure the recorder flag is disabled.	O
`sipTcpConnectionAgingState`	N/A	Enable flag to retain the present behavior. Connections are added to the TCP aging list and are closed if they are idle for more than an hour. When disabled, TCP connections are not added to the aging list and are maintained even if they are idle for more than an hour. Connections will live until intentionally closed or keepalive failures kick in. `disabled` `enabled` (default)	O
`state`	N/A	Administrative state of the SIP Signaling Port. `disabled` (default) `enabled`	O
`tcpConnectTimeout`

0-180

The maximum time (in seconds) the

Spacevars

0	product

waits for

a TCP

an outbound connection to complete. (default = 5). NOTE: This application level configuration has NO impact on any IP layer re-transmission of SYN.	O
`tcpKeepaliveInterval`	60-120	The number of seconds between TCP Keep-alive probes (default = 60).	O
`tcpKeepaliveProbes`	1-10	The maximum number of TCP Keep-alive probes to send until SBC decides that the connection is broken (default = 2).	O
`tcpKeepaliveTime`	60-7200	The number of seconds a TCP connection remains idle before TCP Keep-alive probes are sent out. A value of "0" disables this parameter (default = 0). NOTE: Always configure `tcpKeepaliveTime` with a higher value than `tcpKeepaliveInterval`.	O
`tcpUserTimeout`	N/A	Maximum number of seconds that transmitted data remains unacknowledged before TCP forcibly closes the corresponding connection. Enter a value of 0 (use system default) or value in the range 10-3600.

O

tlsProfileName N/A TLS Profile name used by this Signaling Port. O

transportProtocolsAllowed

N/A

Transport protocols allowed on this signaling port.

If recorder is enabled, the SBC does not handle the following requests. To overcome this, configure a separate SIP Signaling Port towards the recording server (with recorder enabled).
