Firmware IP version 2

(IP BOLD / IP BOLD65 / IP Bellv2 / IP VarioBell firmware updates)

  • Info to GPL license can be found here
  • The firmware upload guide can be found here
  • HW reset guide can be found here.
  • For tech. support, please always send us your enhanced log file. You can find the guide here.
  • You can create your own style file in the web interface setup menu. See an example here.
  • Language files can be downloaded here.
  • If you need the latest FW for IPv1 voip doorphones or voip gateways, please write to support at alphatechtechnologies dot cz
  • How to open a log file of the doorphone e.g. in the Windows Commander program? Rename the log file to logfile.tar.gz, then the log file will open. If it does not open, you need to install a plugin in your Windows commander program for 'tar' files. Inside the log file, there is a directory structure with a lot of information about the doorphone. Log files from the doorphone can be found in the / var/log directory. Of course, every Linux specialist knows this. Why do we use .bin files and not .tar.gz files? Different programs could translate/interpret incorrectly .tar.gz files when sent by email. A file with the .tar.gz extension might come damaged and could not be analyzed. However .bin files do not face this issue when sent by email. Therefore we use the .bin extension for the log file.
  Firmware Date Description
  Attention! Zipped files!   A zipped file - please extract the file .firmware first, then upload the extracted .firmware file to the IP intercom. Do not upload the zipped file to your IP intercom. 20.12.2023
  • Change of password - bug fix
  • On the Streaming page, you can enable the saving of a screenshot from the camera to the SD card (if it is installed)
  • It is necessary to have Internet access and a time server set up so that the images are saved with reasonable time data.

    It works like a circular buffer: after the SD card is filled to about 90%, the oldest pictures will start to be deleted to make way for new ones.

    A 'screenshots' folder will be created on the SD card, with folders by days and hours. 06.09.2023
  • Improved video streaming for internal HD wide-angle camera 04.07.2023
  • Improved Rescue mode when switching the DIP switch to the 'default net' position, where the port for the web interface was not correctly set when the port conflicted with another process (video). If the specified port cannot be used, the IP intercom tries other ports (one at a time) until it finds a free port so that the IP intercom can be contacted on the network.
  • The following is a verified procedure with DIP1 switch - disconnecting flash (do not use DIP2 switch, which is the "default net"):

1. turn off the IP intercom
2. turn on DIP1 if it is not turned on
3. turn on the IP intercom
4. immediately - within approx. 0.5sec. after switching on the power supply, turn off DIP1 (this will force an error in Linux recording)
5. flashes (short flashes) with the LED will appear, if not, return to point 1 above
6. turn on DIP1 (continues to load the 'rescue' web server)
7. the LED flashes (changes of LED flashes 1:1), if not (which is quite unlikely), it is necessary to send the IP intercom for service repair
8. Upload the new firmware via a web browser. Upload the new FW only via a straight ethernet cable (always without any network switch). In case of an error, repeat the process from the point 1 above. 28.04.2023

- a pause can be inserted between the end of the call and the beginning of the next in sequential dialing.
2) On outgoing call attempt plays Error tone if the connection with the Ethernet switch is down
3) RFID reader option:
- communication with Mifare cards and tags, NTAG on 13.56 MHz
- new page "RFID reader" allows you to select an action for a valid or invalid card:
• authorization of the card by an external device via HTTP or HTTPS
• acoustic tone
• relay relay
• email with a photo
- on the title page "Status" there is a new item that displays info about the RFID reader:
• read status is "No" for an unchecked reader
• "Fail" for an undetected reader
• or type detected by the reader
- Email page divided into:
- SMTP server - only set up an email account and send a test message
• Missed calls - items from the original "Emails" page related to sending an email after an unsuccessful call are moved here
- on the SMTP site:
• The new "Security" field allows you to select unsecured or secured email transmission
• the "Save & Test" button before sending the test message first saves the entered values and the test progress is displayed in a special window
• new default values
- minor change to the field in the header of the Phonebook page
 4) On all pages for controlling external devices (relays, RC commands, etc.) where the HTTP URL was entered, it is now possible to enter the encrypted HTTPS protocol
- on all pages where a password is entered, there is a click 'eye' next to the password field to display the entered password instead of black dots
• for passwords sent to external devices, the drive entered password will also be displayed (eg SIP, or SMTP)
• for passwords for access to the gateway, the drive entered passwords are never sent, ie they are not displayed (eg access to the web interface)
5) Email substitutions:
• substitutions $Date$, $Date$, $Time$, $Device$, $User$ can be entered in the subject and body of all emails
• the "Missed calls" page can be added to the subject and body in addition to the substitutions $DialNumber$ and $DialName$
• The "RFID reader" page can only be entered into the body in addition to $Response$, which will be replaced by the content of the HTML message body from the response from auth. server.
6) New SIP INVITE header "X-Config"
7) On the "RC commands" page, the new "iBell Gong" checkbox 21.01.2021
  • VLAN feature in the Network setting menu. Important notice about the VLAN setup: when you set up a VLAN, the IP doorphone disappears from the original network (i.e. the network without VLAN) – of course, this is the principle of VLAN - and you must set up a VLAN on the opposite device, too. If you need the lost IP doorphone back, you must force the factory default settings by the DIP switch No. 2 on the PCB mainboard of the IP doorphone.
  • DSCP (QoS or TOS – Quality of Service) is set on the SIP Settings page for SIP, Audio Codecs page for audio, and Video Codecs page for video.
  • Updated SMTP server settings menu
  • New menu of missed calls

  • When uploading .txt file to languages section, the ".txt" extension is deleted if it´s there. 17.06.2020
  • Fixed "ringback" failure in case of unsuccessful call attempt if the end of the call tone is turned off.
  • Improvement, if a time server (NTP) is set, the use of time from SIP messages is ignored. If both are used and the time is not set correctly by the user, the time is skipped periodically. 24.02.2020
  • Option of external deactivation / activation of Timetable by HTTP protocol

         URL is http://ip_address/timetable_control?N=CMD  where:

         N is the number Timetable (1..10)

         CMD is 'on' or 'off'

         Both HTTP GET and POST can be used

         It is necessary to think of eventually enabling the password request (on the Web server page) for external (RC) commands

Important notice:

The IPv2 doorphones (e.g. IP BOLD) have a new Firmware line as listed above. Switching between the previous Firmware line (up to version 3.4.60) and the new Firmware line (from version 3.5.10) is not possible. If this transition is required, the IPv2 doorphone (i.e. IP BOLD / IP BOLD65 / IP Bellv2 / IP VarioBell / SIP Alphatech-Fermaxv2) must be sent back to the factory to be overwritten with a new Firmware version.


  • In case the IP doorphone has a Firmware V3.0.31 - V3.4.60, then upgrading to V3.5.13 and higher is not possible without sending the unit to Alphatech Technologies company.
  • In case your IP doorphone has a Firmware V3.5.13 and higher, then it is possible to use all newer versions of Firmware listed above. The downgrade to FW versions 3.4.xx is not possible. In case of any more detailed questions, please send them to this email:


Important: If the IP doorphone has Firmware V3.0.31 - V3.4.60, upgrading Firmware is not necessary. However, if the Customer still wishes to upgrade to a higher version of Firmware, the Customer agrees to cover all related shipping and transport, and insurance costs. All related transport costs back and forth are not covered by the supplier (i.e. Alphatech Technologies company or the sales partner), but only by the customer (i.e. the customer who wishes to make the FW upgrade). This applies to all types of IP doorphones with IP BOLD  or IPv2 electronics inside including the IP doorphones under warranty.

  FW version Date Warning! Below listed firmware versions 3.0.xx - 3.4.xx are not compatible with the above-listed firmware versions. 11.03.2019
