Cannot dial 855 toll-free numbers

[TwystedPair]

I am working with an S8500 Media Server.

We are not able to dial the new 855 toll free numbers. I assume this is because it's a new prefix, but I don't know where/how to add it so my switch recognizes it.

The recording we hear is:
Your call did not go through. Please try your call again.

Thanks for the help, like always.

cha ars ana 18. Make note of how 800,866,877 and 888 are routed and add an entry for 1855.
