    Looks promising, but is there a uk version. Main question is it "invisible"
    to a user of a dect phone system connected to it. ie can you just call a
    local number with no local code (as with my orchid dialer at the moment).
    Would it fall back to POTS automatically etc. Anyone using one?

    Not sure what you mean by "uk version"..? You just program it with the
    parameters required for your service provider. If you mean the power
    supply, then it would depend on which country you bought it in, I have a
    Sipura SPA-2000 bought in the US, it obviously came with a US plug on the
    supply, but it's universal voltage so an adaptor soon sorted that out.

    The number you dial depends on whether you're connected to a POTS line or
    the VoIP line. You could of course program all memories to dial the full
    code anyway, this isn't a problem on POTS lines.

    My 2000 doesn't have a POTS port so I have no experience of this, I don't
    need it on my system (VoIP "lines" fed into a PABX where they appear
    alongside the POTS lines).

  7. I have one and use it in a vaguely similar way to your proposal (including
    stringing a DECT off it).

    It will certainly do 1,2,4.

    It has an automatic fallback to PSTN for outgoing calls if power is down, but
    not IIRC if VOIP is not responding.

    You can also set up a dial plan that would route 999/112/local calls via

    It's a very nice pice of kit, though programming it is somewhat reminiscent
    of writing pre-m4 sendmail configurations [that's unkind, but it is certainly
    quite a complex beast].

    The only problem I have with it is that I find the combination with the
    particular DECT I am using leads to a slightly noisy line. I probably haven't
    quite got the UK localisation right though - this is probably the most complex
    single thing to get correct.

    Stephane M:
    Certainly cheaper then Sipura, though it doesn't appear to allow multiple
    The trouble with ATA's they can't do pass-trough to PSTN line, so too many
    phone, too much wiring, another power adapter...

    Thanks for the input so far. How about this one:


    I have looked at the FAQ below (the ht488 has the FXO bit) but I am still
    unclear as to if an incoming call via standard phone line will ring the
    "phone" plugged into the adaptor. I think it will, but not 100% sure !
    I assume no probs with using 1899 voip?
    Also will it pass through caller id to my siemens dect phone system?

    16. What is the difference between FXO and PSTN Pass-Through ports?

    PSTN Pass through port:
    What it can do:
    - Local manual switching between PSTN and IP mode on a per call basis.
    - User can switch to PSTN line by pressing *00 (or the configured
    strings) for each call before they are placed. The device will revert back
    to the default IP mode once the phone is hung up.
    - It can allow a PSTN call to ring/call the phone connected to the FXS
    - It also serves as a life line in case of power outage.
    What it CANNOT do:
    - Terminate a VoIP call into the PSTN port
    - Allow a call from PSTN to route other VoIP devices (different from
    the FXS phone) over the IP network
    - Automatically route calls made by the local user to PSTN line

    Note: On the HT-486 Rev 1.0, the PSTN port is only a life line port
    that switches to PTSN only on loss of power.

    FXO port:
    It can support all the functions of a PSTN pass through plus:
    - Terminate a VoIP call into the PSTN port
    - Allow a PSTN call to call either the FXS phone or other VoIP devices
    over the IP network
    - Route call automatically and transparently to PSTN line according to
    user configuration

    Or this one?

    Yes, the Vigor 2500V (and 2100VG) has VoIP phone pass-trough to PSTN line,
    so it will do what you want, but you will need to manually select the POTS
    line when needed.
    Note that the 2600V does NOT have the pass-trough ability :-(

    Hmm I need it totally transparent. Can you program up like an orchid?

    Tim Morley:
    I don't think so, BUT I don't think there is no reason why you couldn't put
    and Orchid box between your analog phone and the ATA (or router VoIP port).
    Anybody tried that ?

    Funny you should say that! I was thinking about it!
    But then I started thinking what advantage?

    excerpt from web site..

    COMBINE-A-LINE .. Imagine..1=2

    Ever wish you could use your favorite single-line telephone, answering
    machine, caller ID or PC Modem on TWO phone lines?.. Automatically?


    How about joining your VOIP port and the plain old (PSTN) telephone jack
    into a single handset?


    USE a CLT to join a card card acceptor and your single line telephone as


    see if anybody picks-up, on anotheer line trunk, after you are already in a
    telco call???


    Combine-A-Line (CLT) allows two separate calls from two different lines to
    be directed to your single line telephone equipment or PC. Centralizing and
    PROTECTING (SURGE PROTECTION INSIDE) your communication equipment for your
    home office or for the family.

    Combine-A-Line supports all services from your telephone company including
    Caller ID. It also has two line surge protectors to make sure that you are
    Protecting your equipment.

    Use combine-aline to automatically switch between VOIP and pots (rboc) plain
    local line, hands free!.

    SECURITY of your calls are enhanced because the CLT displays if anybody
    picks -up the line after you are in a call! So, it has security features
    just in case someone is wire tapping or listens in after you are in a call.
    The LED display will indicate any disruption to the line.

    Easy to use, No batteries or power supply, and no programming needed! Our
    re-sellers have reported that ..."elimination of the noisy and cumbersome
    power supply wires, reduces the Hum & Noise one hears then when connected
    to household power supplies"

    Automate and organize your telecommunications equipment and desktop wires
    with Combine-A-Line.
