Controls whether a P-Charging-Vector header is created in outgoing SIP messages. When this parameter is enabled

, the SBC creates a new PCharging-Vector header in the outgoing message. When disabled, the

SBC does not create a new P-Charging-Vector header. Creating P-Charging-Vector headers is supported in INVITE and REGISTER messages. It is also supported in SUBSCRIBE, OPTIONS, and NOTIFY messages when received from the same direction as the REGISTER message.

The options are:

• Enable
• Disable (default)

 Controls whether the

SBC creates a Path header in outgoing SIP REGISTER messages. When enabled, the

SBC creates a new Path header in the outgoing message. When disabled, the

SBC does not create a new Path header.

The options are:

• Enable
• Disable (default)

 Controls whether the

SBC creates a Service-Route header in outgoing SIP messages. When enabled, the

SBC creates a new Service- Route header in the outgoing message. When disabled, the

SBC does not create a new Service-Route header.

The options are:

• Enable
• Disable (default)

If SBC offers both pass-thru and transcode codecs, the Minimize Relaying Of Media Changes From Other Call Leg flag effectively suppresses the re-INVITEs to peers when the peer answers with a single codec. However, if the peer has multiple codecs, The Minimize Relaying Of Media Changes From Other Call Leg flag in certain situations can not suppress the re-INVITEs as change in one of the common codecs is detected. In these situations, if the SBC’s most preferred codec matches the peers most preferred codec, the Disable Media Lock Down flag can be used to suppress this Modify Offer. The Disable Media Lock down flag controls the modify offer initiated by SBC to lock down the codec. If this flag is disabled, SBC sends a modify offer to lockdown the codec, if enabled, SBC will not initiate modify offer to lock down the codec. Refer to the Examples below. 

The options are:

• Enable
• Disable (default)

By default, parameters in the SIP URI Refer-To header are passed through to the outgoing INVITE. When enabled, this function is Disabled. When disabled, the URI parameters are copied to the Refer To field in the outgoing INVITE.

• Enable
• Disable (default)

When enabled, the cause value is mapped from the MIME body of the incoming message based on the Q.1912 standard. When disabled, the cause value is mapped from the Reason header based on the RFC3398 standard.
 

The options are:

• Enable
• Disable (default)

The advertised Sonus SIP SDP is described as a set of capabilities that the SBC can receive. The SBC by default issues a Modify Offer ( re-INVITE, UPDATE) whenever it detects a change in receive capabilities. In certain scenarios, the Modify Offer can be perceived as redundant. Enabling Minimize Relaying Of Media Changes From Other Call Leg All flag suppresses redundant Modify offers being sent from the SBC.

When enabled, the SBC suppresses modify offers that have no changes to the “common codecs” that impact the end-user experience. “Common codecs” are codecs that exist both in the initial offer and answer. Changes to common codecs imply changes to DTMF, packetization time, codec specific FMTP attributes and data-path-mode. Refer to the Examples below.

The options are:

• Enable

• Disable (default)

This parameter is used

by the SBC to control whether port number 5060 is sent to the remote peer in the Request-URI of PRACK, ACK, and BYE messages.  When enabled, the outgoing SIP URI does not include the port number 5060 (sip:user@host). In addition, the

SBC only sends out the Record-Route and Route headers of SIP request and response messages with the port number it receives, such that if the

SBC does not receive a port number in Record- Route headers, the

SBC does not send out a port number in the Record- Route and Route headers.  When disabled, the outgoing SIP URI includes the port number 5060 (sip:user@host:5060). In addition, if the

SBC does not receive a port number in the Record-Route headers of SIP request and response messages, the

SBC inserts port number 5060 into the outgoing Record-Route and Route headers.
 

The options are:

• Enable
• Disable (default)
