Hi,
I would like to suggest a great tools. I had check sourceforge.net and find this little program - LINTad. It act as an Answering machine and record the message and convert it to MP3 and you can use your browser to see your incoming voice message (with a PHP script). It also detect if it's a Fax and if so, it receive it and save it as .tif and you can use the same web page to display it.
If someone is able to do a RPM that work for SME 5.12, it would great. I dont know anything about RPM ..
