asterisk users - Dec 2005 - VoIP US - Toll Free Origination / Termination Providers

I'm looking for a provider that can offer VoIP origination and  
termination in the domestic US and Puerto Rico. To be more exact,  
Toll Free numbers origination is a must. I'm looking for a block of  
100 domestic toll free numbers and 100 local DIDs. Estimated traffic  
is about 100K origination minutes and 200K termination minutes.

Please contact me off the list.

Thanks,
Waldo
