Digium's X100P card takes a PCI slot and plugs into your phone line just
as an analog handset or modem would. I assume that your VoIP service is
delivered through some type of analog terminal adapter; an X100P could be
used to connect that as well. (You may be able to configure Asterisk to
connect directly to your VoIP provider. This ability depends on whether
you can persuade the provider to give you the account credentials.) Three
or four X100Ps seems to be the maximum people have been able to use in a
single box (some people may have hit a lower limit?). When your quantity
of lines gets into that range or above, you should consider the 4-port
relative of the X100P or a T1 card and an external channel bank.

This is relatively straightforward to implement in a dialplan
(extensions.conf) either by implementing extensions direction or by using
the DISA application. Keep in mind that a system which allows an incoming
call to make an outgoing call has some inherent security issues
('wardialing' hasn't gone away).
