Disable Media Lock Down

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:

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 ( 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.
