A unique profile identifier.

Mode

The operational state of the SIP Sig Port.

• In Service (default)
• Out of Service

State

The administrative state of the SIP Signaling Port.

• Disabled (default)
• Enabled

IP Interface Group Name

Select from the drop-down list.

IP Address V4

The V4 IP address in dotted decimal form (for example 10.11.12.0 24).

IP Address V6

The V6 IP address in hexadecimal/colon form (for example, fd00:21:445:128::7880 64).

Port Number

The UDP/TCP port number of SIP Signaling Port, which has a default of 5060.

Recorder

Administrative state of the SIP Signaling Recorder Port.

• Disabled (default)
• Enabled
  

NOTE: Ensure that the Recorder flag is disabled when SIPrec flag is enabled.

The administrative state of the SIP Signaling Recorder Port. Enable this flag to use the port for recording using SIPrec Protocol.

• Disabled (default)
• Enabled

When the SIPrec flag is enabled, ensure the Recorder flag is disabled.

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.

TCP Connect Timeout

This parameter indicates the maximum time, in seconds, allowed for 

NOTE: This application level configuration has no impact on any IP layer re-transmission of SYN.

DSCP Value

DSCP value (0-63) for packets from this SIP Signaling Port.

NOTE: This DSCP value marks non-HPC calls. Configure the DSCP value in the HPC profile configuration to mark HPC calls. The DSCP value configured in the Hpc Call Profile for HPC calls with UDP as transport can override the DSCP value configured in the SIP signaling port.

TLS Profile Name

The name assigned to this Transport Layer Security (TLS) profile. The value range is 1-23 characters.

Transport Protocols Allowed

The transport protocols allowed on this signaling port as follows:

• sip-udp
• sip-tcp
• sip-tls-tcp
• sip-sctp

NOTE: The SBC supports only UDP towards the recording server.

SCTP Profile Name

The name of the SCTP profile used for this SIP Signaling Port.

The number of seconds a TCP connection remains idle before TCP Keep-alive probes are sent out. A value of "0" disables this parameter. The value ranges from 0, and 60 to 7200 seconds and the default value is 0. 

NOTE: Always configure TCP Keepalive Time with a higher value than TCP Keepalive Interval.

This flag fetches the RCB value for a user. When this flag is enabled, the RCB value is fetched using only the source IP address and not the source port for generating the hashKey.

• Disabled (default)
• Enabled

NOTE: Disable the Mask IP Addressfor Rcb flag in order to use the Mask Portfor Rcb flag. Both flags cannot be enabled at the same time.

This flag fetches the RCB value for a user. When this flag is enabled, the RCB value is fetched using only the usingsource port and not the source IP address for generating hashKey.

• Disabled (default)
• Enabled

NOTE: Disable the Mask Portfor Rcb flag in order to use the Mask IP Addressfor Rcb flag. Both flags cannot be enabled at the same time.

Enable this flag to enforce AOR matching for messages from registered users.

• Disabled (default)
• Enabled

Use this flag 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 Dry Up Timeout 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.

Dry Up Timeout

Use this parameter to specify the time (in minutes) until which existing calls are allowed to complete in out-of-service mode with dry up action. The value has a range of 1-1440 and a default of 60.

When the Action flag is set to Dryup and SIP Sig Port goes OOS, SBC starts a dry up timer for the configured duration. The SBC exhibits the following behavior when Dryup 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 dry up 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 where no SIP messages are admitted.

NOTE: The Dry Up Timeout flag is displayed when the Action flag is set to Dryup. The Dry Up Timeout flag is configurable regardless of the setting of the SIP Signaling Port state.

This parameter configures the maximum time (0, and 10-3600) in seconds for which transmitted data may remain unacknowledged before TCP forcibly closes the corresponding connection.

• Disabled
• Enabled (default)
