Parameter: Use RTP no-anchoring

The option "Use RTP no-anchoring" is possible only if the option Allow low-delay media relay is enabled first.

RTP no-anchoring is a variant of low-delay media relay where the media is relayed directly between the two legs of a call, rather than going through the SBC unit. This allows greatly reducing IP bandwidth toward the SBC, while still using the SBC for SIP signaling, routing, and other features.

RTP no-anchoring mode is possible within the same conditions that allow low-delay media relay.

Note: Make sure to enable this option only on profiles used for calls that can reach each other directly. It may not work if calls are behind NATs, or on separate networks. We recommend to customize the call leg profiles per route, and to be careful with which routes can use a profile with RTP no-anchoring is enabled.
