    Hi All

    Well reading though the forums looks like my boss has picked the most complicated phone going to try and test out 3CX setup before going live.

    I have managed to get everything sorted now, apart from one issues which is

    Every now and again, the phone will show in 3CX as not been registed, this from what I can tell stops the phone from getting calls. The phone can still make calls. Reboot the phone, and it then works fine.

    In the server event log it gives me event ID 4101

    06.59 extension 105 is unregistered, removed contact: Sip 200@ transport=UPD

    then I get

    07.27 extension 105 is registered, contact sip200@ transport=UDP

    Now I did some googling and found someone said that 3CX expects a keep alive request from the phone to the 3CX system, and they advised to add the below line into the phone config.


    Looking at the phone, it goes from Registered (idle) to Not Registered after about 30min or so.

    but this dosnt look like its fixed the issues....

    Any help anyone can give would be very welcome.

    I thought my config maybe of help

    The Firmware I am using was already on the phone and is SIP41.8-0-2SR1S

    If I need to purchase a support contract with Cisco to get a later FW updated, can someone advise on the URL for this? and what I need to put in my config to get the phone to load it..

    <timeZone>GMT Standard/Daylight Time</timeZone>

    <processNodeName>IP ADDRESS OF 3CX BOX</processNodeName>
    <line button="1">
    <featureLabel>Line 1</featureLabel>
    <proxy>IP ADDRESS OF 3CX BOX</proxy>

    3CX, by default, expects the set to "check-in" (re-register) every 30 minutes (or less), or it assumes that it is no longer available to receive calls. Outgoing calls will usually continue to work, depending on the device and it's settings (allow calls without registration).

    When first registered, 3CX will send a message telling the device how often to re-register. Some devices will "obey" this and some will just ignore it and continue to re-register according to what they have in their settings.

    You may want to change this to 1800 (seconds) or less.

    I though this command in the Cisco config tells the phone to re register


    Looks like I may have the wrong command, does anyone know what I need to place in the config to get the phone to talk back to 3cx... ??
