[Asterisk-Users] Sip to Sip

[chouck]

I appologize if this was already answered somwhere on http://www.voip-info.org/wiki-Asterisk, I'm sure it probably is. And if you wish to just point me to a link that would be appreciated.  I am very new to asterisk and unix all around, so these questions may sound rather ignorant.  First being, how do I setup asterisk to point to another asterisk server and make all the lines which should be PSTN or POTS go directly to another existing asterisk server by using accounts?  For instance, if I was using another asterisk service with my voip phone to connect to it how could I make my local server use that account as a line?    Also, Is there any really good documentation on configuring asterisk, besides the asterisk handbook.  Maybe something a little more indepth and something explaining all the commands available on the console?    Thanks a lot   -chad
