If you are interested in prebuilt solutions, you may consider 
TransNexus's NexOSS product (www.transnexus.com).  The Open Settlement 
Protocol (OSP) they implemented can be used with Asterisk - they have a 
module.  In fact, I am not sure about the commercial status of the OSP 
module as such;  it may be possible to get it free of charge.  Not sure. 
  But OSP is an open protocol, so perhaps it's possible.

Otherwise, I would think that the best way to approach this would be to 
make it fully outboard and divest it of Asterisk.  Implement a SIP proxy 
that forwards to providers using LCR decisionmaking, and just have 
Asterisk send calls to it.  OpenSER can be used for this - and indeed, 
there is an OSP module for it as well, if you wanted to go that route.

If you're dead-set on doing it in Asterisk and don't want to do OSP, I 
would suggest FastAGI.  Definitely don't implement the logic in the dial 
plan, at any cost.
