TTY Call filter directory
The "CallFilter" management interface directory allows for configuration of the call filters. The call filter allows for
processing of the calls with a specific Calling Party Number with a preconfigured protocol, instead of using the
protocol auto-detection procedure. This can be necessary for callers with non-standard behavior, that does not
allow reliable detection of the bearer protocol.
