    I've been playing with VoIP and Asterisk for the past week or so. Reading
    the postings here has been very helpful, but I am left with a few

    Do I understand corretly that it is possible to migrate a landline number
    to VOIP? What I mean is that when someone dials my current landline number
    it doesn't go to the landline, but comes in on my VoIP?

    If so, is the same possible with a block of 10 numbers on an ISDN line?

    My aim is to ditch our ISDN2 line and run everything over VoIP, but it
    would be nice to not have to change telephone numbers...

    It's possible in theory, but it all depends on whether your landline
    and/or VoIP provider can or will do it.

    If you're using Asterisk then Gradwell have a service that may be of use:


    They also do a Centrex service for business use:


    They also have a reputation for reliability, certainly I haven't had any
    problems with my single line, apart from a small problem when I first
    started which was very quickly ironed out.

    Note though that unless things have changed in recent weeks they are only
    able to port in numbers from the London 020 code and maybe one or two
    others, I'm not sure. Peter Gradwell who runs the company posts here
    sometimes, so he may be able to answer your questions.

    Alternatively Voipfone say they can port numbers from most uk areas,
    don't know anyone who's done it yet though.

    Whether or not you can port the numbers will depend a bit on which ITSP
    you're looking at. I've done quite a few ports for VoIPtalk and they
    tend to go pretty smoothly. Downtime should be seconds, if that. The
    main issue we have is that we can only port numbers from the South
    East... :-(
