Hi, I've just bought a Snom HD30L and I'm looking to setup the "auto calling" feature. Which means when the phone is taken from its base, the call is automatically started. I found a menu with emergency calling but it doesn't work. A SIP account is connected and working fine. For now we're using the 3 buttons to make calls in the meantime of finding the solution for the auto call feature.

Any help ?


Best regards

    Hi Me Myself,

    you are welcome and thanks for your request. The emergency calling section inside the webinterface is what you are looking for to setup the "auto-dial on offhook" feature.

    No worries regarding the title "Emergency Dialing Settings" - such use case is possible, but not mandatory.

    In case you like to "auto-dial on offhook" the number 123456789 the related settings for the provisioning / config file would look like:

    call_settings.hotline_delay = 3
    call_settings.hotline_enable = 1
    call_settings.hotline_number = 123456789


    The 3 for call_settings.hotline_delay just reflects the minimum value (in sec. ) that is possible to configure via the phone web interface. But via provisioning you can also configure it to:

    call_settings.hotline_delay = 0

    which leads to an instant auto-dial user experience the moment the handset is lifted.

    Hope you will find this information supportive.

    Thanks, and greetings from Berlin,
    Jan

    Hi Jan,

    How do I provision these 3 settings ?

    Best regards

    To be able to provisioning these settings and others if needed ( btw: settings are documented in the Snom Hospitality SIP Phone Configuration Guide available in our manuals section),

    I see 3 options:

    1. with our SRAPS cloud solution (secure redirection and provisioning service): https://www.snom.com/en/services/sraps/
    2. using the Hotel Phone Admin tool for a locally managed staging / provisioning: https://service.snom.com/display/wiki/Snom+Hospitality+SIP+Phone+Administration+Tool
    3. create and deploy their own provisioning repository combined with redirection via DHCP vendor specific options / option 66 etc.

    of course, all options have their pros/cons.

    Best regards,

    Just figured out a little "workaround" with the help of the Firefox browser (Web Inspector) - it is possible to change the value to 0 before pressing the Save (submit) button inside the web interface.

    This way you can set call_settings.hotline_delay = 0

    but of course just on one single phone.

    If interested, please feel free to reach out and I describe you the steps for this "workaround".

    Best regards,
    Jan

    Thanks for your intels.

    Unfortunately the Hotel Phone Admin tool doesn't find the phone on the network. I can reach the web interface from the same computer where the software is installed.

    I guess the HL30L (HD 300 on the web interface?) is not compatible ?

      You are welcome.

      The HD30L is software wise identical to an HD300. The only difference HD30L vs HD300 is in hardware: HD30L keypad button top shell is re-sealed, so access to the key's (still full functional below the plastic) is blocked.

      Therefore and to streamline PBX certifications & system onboarding processes they share the identical software.


      Regarding the Hotel Phone Admin tool, - it is "compatible" to all of the SIP / IP phones in our hospitality portfolio. The tool reads out the model (learns the model type) after successful login into the device web interface (not in advance).


      The most likely reason it fails to detect the HD30L is from my point of view, one major software change enforced by the UK PSTI regime:
      The UK Product Security and Telecommunications Infrastructure (Product Security) regime - GOV.UK

      Part of this is the need that embedded devices like IP phones must request the user to change the default web interface password to a desired new one, before a full login is possible.

      This software "design" change affects the detection process of the Hotel Phone Admin tool: usually the initial (default) password is entered in the tool and with that it's starts to search for phones in the network - the defined IP range.
      While the initial password might be accepted by the phones web interface, the follow up user dialog demanding a new password is nothing the Hotel Phone Admin tool is capable to handle, - so it fails to login and by that fails to read out the model type.

      With such UK PSTI compliant software the Hotel Phone Admin tool needs to be configured with the "new" user defined (none-default) password to successfully detect & manage the phones.


      Back to the original topic: "Auto-Dial on Off-Hook" configuration with a delay of 0 seconds - the Firefox browser "shortcut":

      When you have opened the Emergency Dialing Settings subpage ( /system_hotline.kl1 ) within the HD30L web interface you can right click the selection menu for the Delay (secs) and select the Inspect element (Q) option.

      Inside the Firefox Inspector HTML view, a line will be highlighted, looking like:

      <select id="103" name="103">...</select>

      you click on the 3 dots and this will expand all the options in the HTML view.

      Rightclick the line: <option value="3">3</option> and select Edit HTML

      edit the line from above to: <option value="0">0</option>

      and leave the edit mode by selecting another line. After this the selection menu will show you the 0 seconds options.

      You can select it and press the Save button.


      This way the value of 0 is stored, even the webinterface will recover to its original look and feel (as the change is only temporally inside the firefox of course).

      With the 0 stored, the call will be executed instantly - after the handset is lifted.

      Thanks,
      Jan
