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.
