[Asterisk-Users] How do I set up extensions.conf to dial out on analog telephone line?

[Robert La Ferla]

I have one SIP phone (and soon a 2nd phone) and a Digium TDM11B (1 FXO + 
1 FXS) card.  I would like to be able to dial out the analog line via 
Asterisk.  How do I configure that?

i.e  I'd like any extension to be able to dial 411, 911, 0,  (617) 
555-1212, 16175551212, etc... and have these routed out the POTS line.  
Just like a regular telephone.
