Usage guidelines

An INVITE request with SDP Offer is an early offer, and an INVITE request without SDP Offer is a delayed

offer. Some service providers mandate early offer calls for charge security. To meet this requirement,

enable DO-EO conversion on the SIP trunk device.

This command does not takes effect if codec transparent transmission or media flow-around is enabled.
