• In a documented CVP 11.6 flow, calls dropped at the 30-minute mark when CUCM sent BYE with cause 41 after a session timer negotiation mismatch. in context
• Cisco's fix for the CVP case makes the ingress CUBE the refresher with min-se 1800 session-expires 1800 and session refresh under voice service voip sip. in context
• Cisco TAC attributes the CVP drop to CVP omitting session timer headers in re-INVITEs so each endpoint could assume the other was the refresher. in context
