What's New in Version 2.4.2

The following new features are supported in Version 2.4.2:
Call Waiting Reminder Ring (CWRR). If a user on-hooks the phone and there is another call (a call
on hold) or a call waiting, the user hears the phone ringing, indicating that there is someone waiting
on the line.
Distinctive ringing. The ringing tone can be defined by the Alert-Info header in INVITE or 180
Ringing SIP messages. The ringing tone defined in the Alert-Info header is played locally.
Automatic Dialing (Hot Line): When this feature is enabled, an automatic call is placed when the
user off-hooks the phone. The user should configure the phone number that is automatically dialed
and the timeout between off-hook and phone call execution.
Secondary Dial Tone: When this feature is enabled, a secondary dial tone is generated when the
user off-hooks the phone and dials a preconfigured digit.

period of time (configurable).
