    Hi all,

    Is there a way I can configure the Linksys SPA-3102 so when somebody
    tries to contact me while I'm having a conversation over VoIP, (s)he
    gets a busy tone? Now it just looks like I'm able to pick up the phone.

    Any suggestions?



    Hallo iedereen,

    Is er een manier waarop ik de Linksys SPA-3102 kan configureren zodat er
    een bezettoon klinkt wanneer iemand mij probeert te bereiken terwijl ik
    zelf een gesprek over VoIP aan het voeren ben? Nu gaat de telefoon
    gewoon over terwijl ik ze niet kan opnemen.


    Alvast bedankt,

  2. I don't believe this is possible on the SPA-3000.
    It would require that the VoIP in the FXS port could signal the FXO
    port to busy-out (go off-hook without dialling). There is no SIP
    message to request a busy-out (although with both VoIP adaptors being
    in the same unit, it could use a non-SIP way of signalling this inside
    the SPA-3000/3102).

    You're not the first one bumping into this :) Just check out Google.
    Technically the only way a SPA-3102 can make your analogue line (POTS)
    "busy" when busy at the VOIP-side is "picking up the receiver" on the
    analogue line. There is probably no telco that sees this as a legitimate
    action, so no hardware manufacturer will implement a "trick" like this. So
    the SPA-3102/3000 has no setting to keep the analogue line "busy" during a

    Maybe an idea to briefly changebetween VOIP and POTS with the flash-key of
    your phone to tell the caller "that you're busy on the other line" and call
    him back later? I never used it, but I think the SPA's support this.


    Je bent niet de eerste die hier tegenaan loopt :) Zoek maar eens op
    google. Technisch de enige manier waarop een SPA-3102 jouw analoge lijn
    (POTS) op "busy" kan zetten als je in gesprek bent aan de VOIP-kant, zou
    zijn door "kunstmatig de hoorn van de haak te nemen" op de analoge lijn. Er
    is denk ik geen enkele telefoonmaatschappij/regelaar die zoiets als een
    legitieme aktie ziet, dus hardwarefabrikanten zullen zo'n "truc" niet
    inbouwen. De SPA-3102/3000 heeft dus geen voorziening/instelling om de
    analoge lijn "busy" te houden tijdens een VOIP gesprek.

    Wellicht werkt even wisselen tussen VOIP en POTS met de flash-toets, om te
    vertellen dat je "op de andere lijn in gesprek bent" en later terugbelt? Nog
    nooit gebruikt, maar volgens mij ondersteunen kunnen die SPA's dat wel.


    P.S. Misschien was het handiger als je in deze 2 nieuwsgroepen onafhankelijk
    van elkaar gepost had. Scheelt mij een hoop tikwerk :)

  4. This is called busying out the line, and is a standard feature
    on all telco POTS telephony systems.
    There is no SIP message to busy out a line, so it's not something
    a VoIP unit can support using SIP protocol alone.

    So how come my Fritzbox can do this? It rejects calls on busy, which then
    relies on how the SIP provider handles this. This could be a busy tone or
    it could be divert to voicemail. It can also be an NU tone (e.g. Sipgate)!

    I seem to remember there is a "Busy here" message through SIP?

    So how come my Fritzbox can do this? It rejects calls on busy, which then
    I think there is some confusion here: the original poster wanted to "busy
    out" (to use Andrew's term) the POTS line, not the SIP-line.

    Ah yes, I now see the implied meaning in the OP's original message. If this
    is the case then forget what I said...
