I have been looking for a telephone call answering machine program for Linux, but I haven't had much luck. In Windows, I have used CallStation (http://imptec.com/callstation.htm) for many years. I am looking for something like CallStation where calls can be answered or hung-up on, faxes can be received, Caller ID is shown, calls can be recorded in their entirety, etc. Is there anything like that for Linux?

In fact now in Windows (I believe this started with either Windows XP or Vista) calls and recordings can only be recorded for like 55 seconds. I have heard it is because Microsoft changed something with Windows' voice modem support. I am hoping Linux does not suffer from this.
