[asterisk-biz] 3-4 line analog cards for Asterisk

[admin at mmri.us]

1) Which analog 3-4 line cards are supported by Asterisk ?

2) I need to use 2 lines for incoming calls and the other 2 lines to
route to other outside CS I contract.
Can asterisk be configured to route calls from an arbitrary analog line
on the card to any of the other lines?

Somehow the user manual and Faq never describes real scenarios and
rather refer to code issues.
