Specifies whether or not to add a P-Charging Function Address header.

The options are:

  • Disable (default)

Disable Media Lock Down

If the SBC offers both pass-thru and transcode codecs, the Minimize Relaying Of Media Changes From Other Call Leg flag effectively suppresses Re-INVITEs to peers when the peer answers with a single codec.

Minimize Relaying Of Media Changes From Other Call Leg All

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 ( reRe-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 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 See examples following the table.

In addition, the SBC only sends out port numbers in 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 if it receives a port number in Record-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 the port number 5060 into the in outgoing Record-Route and Route headers.
