Hi people, greetings to all of you people, I'm new.

My question and problem is:

I want to setup a dial-in server with ubuntu-server mggetty,pppd,
I have paid a hosting mailserver in spain and want to my friends connect to my home server ( dial in server ) and in my email server they send emails locally and retrieve from my pop3 server, and later on my server dials-out and send the emails and receive from my hosting company, that's not the problem for me, now, I haven't the config working right now because I dont't have the serial modem in this momement until next week, the config for dial-in I think it's pretty straighforward so far based on what I read but I'm in doubt because I read in some docs that mgetty when listen on the modem blocks the line and this doc says that I cant use my phone to call people o get incoming calls from people only dial-in connections, this is not what I want because I want my 3 friends connect to diferents hours and when the finish sending/retrieving the mail then disconnect and then I can use phone line to make calls, or to receive another dial-in request from other friend, any one can help me?

mgetty has a ringback feature where you dial and let the phone ring once, hang up and call within a specified number of seconds and the MODEM will answer.

My native languaje it's now english, I dont' understand what you say, can you explain more?, and remember I need to be able to use my phone to make calls and talk and to let people dial-in and let the server dial-out too.

mgetty will automatically answer after the phone rings. However, there is also what is called ring twice which will also let you use the same phone line for receiving voice calls including an answering machine. Here are the steps:

1. Manually call the server. Hang up after it rings once.
2. Wait 30 seconds. This time can be programmed.
3. Call the server again, the MODEM will answer.

The MODEM will not automatically answer if you do not do step 1 so the phone can be used to talk and let people dial in.

See the -R option.
