    I want to use the PSTN connection on my SPA-3000 to connect to a '
    door phone' (just a standard phone).
    I have simulated the line by a 50V d.c. supply connected via a 1k Ohm
    resistor - I have used this rechnique successfully before to link
    I have tried to connect to the line, in the dial plan, by:-
    and also by
    Neither work.
    I have enabled the line under 'PSTN Line'.
    All I want to do is to be able to dial #00 and for the house phones to
    connect to a phone on the simullated PSTN connection.
    Is it not responding because the ATA requires a dial tone or are there
    some other settings I need to change?
    Suggestions please!

    I don't think you need to do this bit.

    If the door phone behaves just like a normal phone, then you need to
    connect to the phone side of the SPA-3000.

    If you wanted to connect other phones too, then you need an SPA-2002.
    This has two phone ports.

    I am not sure that you have understood my question. On the SPA-3000
    there is a socket intended for PSTN. That means that will connect to a
    'powered' line. If I had a BT line there, for example, I would be able
    to connect to it from my other phones dependent on the settings of the
    ATA. I simply want to 'dial in' to a phone on that line. I have a
    locally powered line and a phone connected on that port. All I need
    to do is make the phones on the voip side connect with that phone in
    the same way as they would if it was a standard landline. The ability
    to connect to that port is a standard operation of the SPA-3000. My
    question relates to what settings or changes I should make to get this
    up and running.
    My dial plan for that connection is <#00,:><:mad:gw0> and I have nabled
    the line. Now, as it isn't working, but giving an unobtainable tone,
    what other changes should I make - that is the question. For example,
    does the ATA need a dial tone to operate.

  4. I would try a scheme which doesn't include # or * to start
    with, just to rule out those characters as being the problem.
    I would have a look at the web interface "info" tab,
    PSTN Line Status. That should tell you what state the
    SPA-3000 thinks the line is in.

    Brian, I found it impossible to get the SPA-3000 to select a gateway
    using #0 as the code. It works with every other digit apart from zero.
    and see if that works. It seems to be an undocumented feature that zero
    cannot be used for gateway access.

    I have #0 working to give me a gateway on my SPA3000

    Which gateway does it work with?

    It actually goes to my main registered gateway, so maybe that is why it
    works?, ie

    Normal calls go via gw1
