Source notes citing this source

• The 2018 CUBE technote gives both the recommended Session-Expires and the default Min-SE as 1800 seconds, and advises against setting the session timer lower. in context
• CUBE handles session refresh on each call leg independently. With 'midcall-signaling passthru media-change', it consumes mid-call re-INVITEs locally and passes them to the other leg only when media changes. in context
• The CUBE 'session refresh' command under voice service voip / sip adds a Session-Expires header to outbound INVITEs when the inbound INVITE did not carry one. in context
• Cisco TAC advises setting the session refresh method to INVITE instead of UPDATE for CUCM 10.x onward to avoid UPDATE refresh interop issues. in context
• With midcall-signaling passthru media-change, CUBE consumes refresh re-INVITEs and passes a session refresh across to the other leg only when media changes. in context
• On CUBE, the session refresh command under voice service voip sip adds a Session-Expires header to the outbound INVITE when the inbound leg had none. disputed in context
• Cisco TAC shows a CUBE SIP profile rule that removes UPDATE from the Allow header so peers do not choose UPDATE for refreshes. in context
• Cisco TAC states CUCM sends a default Session-Expires of 1800 seconds, which can be raised to a maximum of 86400. in context
