What is acSysHTTPClientCASFileURL?

AC-SYSTEM-MIB::acSysHTTPClientCASFileURL specifies the URL (up to 254 characters) for a Channel Associated Signaling (CAS) file, which defines how the gateway interprets on-hook/off-hook and tone-based signaling from legacy analog phone systems. CAS is still used by many traditional PBX systems and carriers, so operations teams need to keep CAS tables current across their fleet. For example, setting it to https://signaling.company.com/cas-definitions.dat ensures all gateways can properly decode multifrequency signaling from older switch equipment.

Examples
