• The disable-early-media 180 command was introduced in Cisco IOS 12.2(13)T. A system keyword and voice class tenant support were added in 15.6(2)T and IOS XE Denali 16.3.1, and YANG support in IOS XE Dublin 17.10.1a. in context
• The Cisco IOS command disable-early-media 180 (sip-ua or voice class tenant mode) makes the gateway ignore SDP in a 180 response and play local ringback; the no form restores early media cut-through. in context
