• Under call-manager-fallback, ip source-address sets the address and port (default 2000) on which the router accepts SCCP phone messages, and the strict-match keyword enforces strict IP address verification. in context
• In call-manager-fallback mode, max-ephones and max-dn both default to 0, and their maximum values are platform-dependent. in context
• After max-ephones or max-dn has been set, the router must be rebooted to reduce the limit. in context
• SCCP SRST is verified with show call-manager-fallback all (feature enabled) and show ephone (phones registered to the SRST router). in context
