Caption
0 Table 1 Sip Sig Port Parameters
Parameter Description Index A unique profile identifier. Mode The operational state of the SIP Sig Port: outofService inService (default) 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 Specifies the V4 IP address in dotted decimal form (for example 10.11.12.0 24). IP Address V6 Specifies the V6 IP address in hexadecimal/colon form (for example, fd00:21:445:128::7880 64). Port Number UDP/TCP port number of SIP Signaling Port (default is 5060). Recorder Administrative state of the SIP Signaling Recorder Port. The values are: disabled (default) enabled Note Ensure that the Recorder flag is disabled when Siprec flag is enabled, Siprec Specifies the administrative state of the SIP Signaling Recorder Port. Enable flag to use the port for recording using Siprec Protocol. The options are: 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. Include Page Note When Siprec flag is enabled, ensure the Recorder flag is disabled.	Not_for_SWe

TCP Connect
Timeout

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

Spacevars
0 series

to establish an outbound TCP connection.

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.

TLS Profile
Name

The name assigned to this Transport Layer Security (TLS) profile. Must be 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

Specifies the name of the SCTP profile used for this Sip Signaling Port.

Tcp Keepalive TimerSpecifies 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 60 to 7200 seconds and the default value is 0. Tcp Keepalive IntervalSpecifies the number of seconds between TCP Keep-alive probes. The value ranges from 60 to 120 seconds and the default value is 60. Tcp Keepalive ProbesSpecifies the maximum number of TCP Keep-alive probes to send until SBC decides that the connection is broken. The value ranges from 1 to 20 and the default value is 2. Mask Portfor RCB

This flag is used to fetch 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. The options are:

• disabled (default)
• enabled

Note
The flag Mask Ip Addressfor RCB must be disabled to use this flag. Both flags cannot be enabled at the same time.

Mask Ip Addressfor RCB

This flag is used to fetch 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. The options are:

• disabled (default)
• enabled

Note
The flag Mask Portfor RCB must be disabled to use this flag. Both flags cannot be enabled at the same time.

Action

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 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

Note
Dry Up Timeout flag is displayed when Action flag is selected as Dryup.

 

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. (range: 1-1440 / default = 60)

When Action = Dryup and Sip Sig Port goes OOS, SBC starts a dry up timer for the configured duration. 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 dryup timer expires, 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.
