[Asterisk-Users] Asterisk and LCR

[Waldo Rubinstein]

I'm wondering how you guys handle least cost routing within Asterisk.

Basically, we have a few providers with, obviously, different rates  
per route. Additionally, we have a number of clients who have DIDs  
assigned to them (either pointing to a single SIP peer or to more  
complex dialing rules, such as, ring multiple SIP peers, or ring SIP  
peers sequentially, or overflow to external forwarded number).

What we are trying to do is to ease the pain of Asterisk dialing  
through the least cost route regardless of where the destination is.  
If the call is to go through a provider, well, then dial the least  
cost provider. If someone is dialing a number which happens to be one  
of the DIDs assigned in our system, it shouldn't have to go out  
through any provider but just be routed properly in the dialing plan.

Also, if a client has defined a rule to forward calls to another  
number, how can I let the dial plan to dial out that number while  
taking advantage of the LCR in place?

We looked at lcdc script but not quite sure is what we need or maybe  
don't understand it completely to implement it correctly.

Thanks,
Waldo
