Sprint BGP filters in 207.x.x.x?

MCI aggregates all its customer's routes into /19's.  We have just 
received our first block of address space from the 207.x.x.x range.  If 
you continue to filter at /18's for the 207.x.x.x range, you won't be 
able to reach all of MCI's customers.

Needless to say MCI would appreciate it if you'd change your policy to be 
/19's, and I'm sure Sprint's customers would appreciate it as well.

Regards, Daniel
