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 for many years. You can find out more about it at http://imptec.com/callstation.htm and be sure to click the FEATURES and SCREENSHOTS buttons at the top of this link as well for more information.
I am looking for a Linux equivalent of 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 this 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.
