We've got a local Telco and Frontier prefixed that we can't port to ANY voip provider, only to cellular providers. No one has been able to find a way to port these prefixes or some other ones I didn't list here.

Ah, the world-famous Kasson and Mantorville Telephone Company! :-) Those tiny ones can be tough. They are in LATA 620 but subtend the Plymouth tandem, which is in Minneapolis LATA 628. Odd, but there are a number of those exchanges in the Rochester LATA. That tandem belongs to Minnesota Equal Access, a sort of CLEC that runs a tandem on behalf of many small ILECs. Maybe they could help you.

Their prefix codes are local but a CLEC generally needs an interconnection agreement with them, and I doubt many have them. Just not worth the bother. But I do see Mantorville numbers belonging to Sprint-CLEC, MCC, and bandwidth.com. So they may have arrangements.

507-528
507-527

Those are Frontier Citizens, the old (not ex-GTE) rural ILEC. Portable but not pooled. Both remotes of the Kenyon switch, on CLQwest's Owatonna tandem. Jaguar Communications is the only CLEC with Claremont numbers; Sprint and MCC have West Concord numbers.

    As a general rule, any rate center's numbers can be made portable
    if they aren't already so.  It can worst case take six moths to
    implement.  But that was usually done long ago.

    However, in order to port a number into a rate center, the carrier
    (CLEC) needs connectivity to the tandem switch that serves that
    rate center, which may belong to the ILEC in that rate center, or
    a third ILEC, not the one in the bigger exchange next door.  If
    you tell me the rate centers in question I may be able to
    determine that for you.  CenturyTel[/link] is notorious for being
    uncooperative, hoping state regulators let them bend the rules
    their way.  And some rural ILECs think they're exempt from
    interconnection rules, though they're not.  So it would not be
    surprising if the underlying CLECs just don't touch those RCs.

        Typically, you can check to the local calling guide and if
        the rate center with the numbers is local to a rate center
        your providers are in, you should be good to go. YMMV.

        *Subject: *[WISPA] Number's that can't port to VOIP


        We have a customer on fringe of a rural Century Tel area and
        both of our voip providers came back saying they were unable
        to port the number for us. Are there remote areas where you
        still can't port a number? Is there a way to find out if
        anyone can port this number? Like a master list or database I
        can search?
