[Serusers] Outbound dialing setup

[Doug R]

I'm using the script from http://lists.iptel.org/pipermail/serusers/2004-February/005996.html
(the first ser.cfg).  I'm trying to figure out where to include my SIP outgoing calls to my Asterisk PSTN server.  For example, let's say I want  to transfer a SIP call for a local XXX-XXXX number to pstn.xyz.com port 5050.  How would I set that up?  

Additionally, I'm rather confused as to which section I would put a dialplan into for say connecting to FWD users, etc.  Again, like before if I wanted to send a certain call to a certain termination point, let's say 407-xxx-xxxx, I want to send that to one IP, and 954-xxx-xxxx I want to sent to a different one.  Where are those statements supposed to be?

Thanks a lot...
