• SIP TLS zones may fail to come up when certificates use an 8192-bit key; Cisco recommends 4096 bits. in context
• MRA can fail if the uploaded private key file lacks a trailing newline character. in context
• With TLS verify enabled on a zone, the neighbor's FQDN or IP address is checked against the certificate holder name, so zone peer addresses should be FQDNs when certificates carry peer or cluster FQDNs. in context
