[cisco-voip] LCR software for VOIP

[Alex Balashov]

Using a SIP proxy, or a B2BUA.

Even if your calls are going back out as TDM, SIP is a high-level 
protocol subject to easy destination manipulation using inline database 
logic and mediation, whereas SS7 or Q.931 are not.

So, have some dial peers per carrier that require particular prefixes to 
access them, then deliver your user calls to a proxy that can then do 
the appropriate translations (based on the LCR values) and send the call 
via SIP to your media gateway.

Never, ever, ever take an approach that requires thousands of dial 
peers.  This is a terribly stupid, wasteful, and inefficient idea.  You 
need to route the calls through a central, intelligent entity.
