We are a CLEC and regularly port numbers over from the ILEC (ATT) who we have an ICA with. Would we be able to port cellular/wireless numbers from say Verizon or Sprint over to us as a landline CLEC without an ICA? I know we could do it from the Neustar/NPAC side of things, but would Verizon/Sprint/etc. release the number? Thanks! -Eric
