Secure Open Door Peering with GDS37xx

This feature requires GSC3570 and GDS3710/GDS3705 paired together to function. With GDS3710 or GDS3705 installed outside, the GSC3570 is installed inside, the strike or lock is wired directly to the Alarm_Out interface of GSC3570 to control the door from inside, therefore more secure compared to the strike wired directly to GDS3710/GDS3705 at outside. Below is the application scene illustration:

Notes

GDS3710 firmware 1.0.7.19 or above / GDS3705 firmware 1.0.1.13 or above, are required to work with GSC3570.
Only one door can be controlled due to GSC3570 only has one Relay Control circuit.
If multiple doors need to be controlled by GSC3570, SIP call is required, and the door strike/relay should be controlled by related GDS37xx directly.
The GSC3570 will turn on LCD when device in energy save mode (LCD Off) when secure open door event happened.
When receiving an incoming call, a 3rd party audio/light strike device can be triggered by Door Open Port.

Connecting GSC3570 with 3^rd Party Door Access Systems

By selecting and configuring the supported related 3^rd party door access system here, when GSC3570 is in SIP call with DTMF open door operation, the “Soft Button” preprogrammed will appear in the GSC3570 touch screen. The user will be able to press the soft key to send the Open Door PIN to a related 3rd party door access control system to open the door.

This is an enhancement to help system integrators and customers to integrate GSC3570 with 3^rd party Door Access Control system to operate the open door remotely.

*External Service 3rd Party Door Control Systems: Web Configuration*

Note

Starting from firmware version 1.0.5.21, The number of external service operations supported has been increased from 10 to 20.

Using GSC3570 as Doorbell and Door opener

The GSC3570 can behave like a doorbell and an open door if the door strikes wired directly to the relay control port of the GSC3570. For licensed electricians, this is a perfect digital upgrade solution for users with a broken traditional analog doorbell system. The existing wiring and switch can be connected to GSC3570 so when visitors press the door switch the GSC3570 will play DING-DONG doorbell tone. If connecting the electrical strike directly to the GSC3570 relay control port, a 3d party audio/light strike device can be configured to be triggered when the GSC3570 receives an incoming call, then the user can press the Open-door Icon from GSC3570 to open the door directly. It can combine with the GSC36xx IP camera to form an absolution package.

*GSC3570 as Digital Doorbell and door opener example*

This feature is designed to allow GSC3570 to function like a traditional doorbell, and open the door if wired to an electric lock, a simple digital upgrade to a traditional (broken) doorbell. If combined with an IP camera, it can help to monitor and update the home security without paying the subscription fee usually involved for such a service.

The wiring example of GSC3570 as doorbell and open door:

Wiring:

A switch (doorbell button) needs to be wired to AIN1 (Blue), AIN2 (Brown) or AIN3 (Grey) and Ground (Black).
The label is printed in the back of GSC3570 and a cable with color code is provided with the package. Maximum 3 switch/button can be connected (example: Front Door, Back Door, Garage Door) But ONLY 1 electrical lock or strike can be controlled (because GSC3570 only has 1 relay control port (COM1, NO1/NC1).

Configuration from Touch UI Screen:

Below are the screenshots of how to configure and enable this feature. This feature is revised from Zone/Alarming feature; therefore, THREE steps are required:

I. DO mode set to “Alarm out” or “Open door”:

From touch UI, press “Settings”, select “DO settings”
Choose “DO mode”, select “Alarm out” if no door strike connected and only want to use the Ding-Dong doorbell tone. No virtual open door button will be displayed in Alarm Message.
Choose “Open door” if COM1, NO1/NC1connected to strike to control door opening. Green virtual open door button when be displayed in Alarm Message when doorbell switch pressed
Press “<” to exit and select “√” sign to save the change just made.

II. Edit Zone setting for Doorbell:

From touch UI, press “Settings”, select “Zone settings”
Press “Zone settings”, default there are 4 zones, Only Zone 2, Zone 3, and Zone 4 can be used for Doorbell switch (Zone 1 is input requiring power). Press related Zone (2 to 4) to edit. The screenshot for example, Zone 2 is changed name to Front as“Front Door”and“Zone type”is changed to “Doorbell”. Press the up right corner “√” sign to save the change just made. Then exit to “Setting”UI page.

III. Enable the Arming mode to enable the doorbell:

Press “Arming mode” to enable the change in above Step I.
Select the Arming mode used. For example, “Outdoor” is selected because the doorbell is located at outside. Swipe the grey button to enable the feature, the button will become blue when enabled.
Press “<” icon to exist the configuration to idle screen.

The “Arming status” icon will change color (green). To show the device is “Armed”, or the feature is enabled.

Now press the doorbell or switch (AIN1and GND short-circuit), “DING DONG” doorbell tone will be played at GSC3570, a green open door virtual button will be displayed in the screen (if configured and wired the strike). Press the green “Open door” virtual button, the relay will take reaction to open the door. The GSC3570 top right corner will also display a door opened icon and an “alarm” icon and “Message” will be displayed with front and back red LED flashing, reminding there is an open door (alarming) event happened. Press the “Messages” icon to check what the message is then exit the UI, the alarm message and the flashing LEDs will disappear.

Alarm flashing icon and open door button

Open Door via GDS37xx with or without a SIP Call

This feature is requested by customers and implemented to meet customer’s application requirement, where GDS37XX paired with GSC3570 to open door while no sip call required.

This feature needs related matching GDS37XXfirmware to work. The minimum firmware version needed:

GDS3710: 1.0.7.19 or higher.
GDS3705: 1.0.1.13 or higher.

From GDS37XX side, the configuration is the same. Only difference is the number of doors be controlled: If using Local Relay controlled by GDS37XX, TWO DOORS can be controlled.

If using GSC3570 Relay, ONLY ONE DOOR can be controlled. The PIN and other settings are the same as SIP remote open door or GSC3570 secure open door.

The difference will come out at the touch screen UI operation of GSC3570.

Door opening with SIP Call:

This is as previous firmware, when GSC3570 established call with GDS37XX, the screen will display virtual open door button(s), and user will press the button to open door:

Note

During active calls, big icons can now be displayed on the call screen with the firmware update to version 1.0.5.21

GSC3570 Open Door NO SIP Call:

This is new feature. At the GSC3570 idle screen, press “Monitor →Door system”, the related GDS37XX will be displayed. In the blue bar, left is a “Phone”icon and right is the “Open door”icon. The“Phone”icon will establish SIP call as previous firmware behaved.

Press “Open door” icon, the GSC3570 will open door directly and NO SIP CALL will be established. Depending on how many doors controlled, if one door configured, the door will open directly; if two doors configured, another screen will pop up to allow user to choose which door to open, as shown below:

When the door is successfully opened the following message will appear:

Starting from Firmware version 1.0.5.30, when you receive an incoming call, the call preview will show both doors and allow you to open them, as shown in the illustration below:

Note

If using a 3th party Door system instead of GDS37xx , then the GSC3570 will send DTMF message to opendoor.

RTSP Audio Volume Control

The touch LCD screen is improved by adding “Speaker” icon when RTSP stream is displayed. This feature allows the user to adjust the volume of speaker to increase or decrease the audio of the RTSP media stream.

Touch the white “Speaker” icon will make it becoming blue, and a vertical bar will appear at the right side of the blue speaker icon. Touch any part of the screen will exit the operation.

Screen Snapshot During RTSP Streaming or SIP Video Call

This feature does not need any configuration and enabled by default, but SD card is required for this feature to work correctly.

RTSP Streaming: During RTSP steaming, in the middle of the screen, a virtual “Snapshot” button will appear. Press that button will capture current screen and the snapshot will be saved in the SD. The file path will display in the screen then disappear.

SIP Video Call: During SIP video call, press the “More” icon will pop up another screen, the “Screenshot” icon will be displayed. Press the “Screenshot” button will capture current snapshot and stored it in the SD card.

The file path will display in the screen then disappear after a while. Press the “File «icon from GSC3570 idle screen, select “videoshot” file folder, the snapshots will be stored based on folder using “date” when snapshot taken. Select related folder will see the snapshots stored.

HTTP GET Request

By selecting HTTP as the service type the user can use a button from the touch screen to generate an HTTP GET request to open the door.

When the device in the door system list calls, an open door button appears corresponding to the URL specified under the field HTTP URL.

Connecting IP Camera with GSC3570

The GSC3570 can be configured with up to 32 IP Camera, the configuration is done as follow:

Web interface configuration:

Switching to RTSP Monitor during an active SIP call

This feature needs working SIP call and RTSP stream preconfigured. This feature will work with GDS37xx or any Grandstream SIP phones and Grandstream IP cameras or even some 3rd party IP cameras. Below is an example usage scene diagram:

*Video Monitor Switching During an Active SIP Call*

This new feature is designed and implemented based on feedback from customers. It can help to increase safety but keep convenience, used in public scene like School/Campus, Dorm/Hallway, Hospital, Library, Gym, Theater, Club, etc.

Basically, in open/public space where there is a GSC3510 Audio Intercom or IP phone (or GDS3705), User (e.g.: student) pressing emergency button or make a call to GSC3570 (e.g.: security guard).

If the same location has installed an IP camera or a door system, once the call is established and in session, the GSC3570 will display RTSP icon on the right side of touch screen UI, pressing RTSP icon and selecting the related IP Camera as shown in below screenshot, then the call will automatically be put ON HOLD, the person at GSC3570 side can see the RTSP live stream, he can either continue monitoring the RTSP stream or switch back to continue talking to the caller.

Considering the following scenario as an example :

Bob Calls Carl on the GSC3570.
While Bob and Carl are on Call, Carl can press the RTSP icon shown on the below screenshot to monitor the video camera.
Once Carl starts the monitoring, the call is automatically put on hold with Bob until Carl decides to return to the call by clicking the Back button.

Note

The call can only be hung up from the other party (Caller party) and not from the GSC3570 side when the call is hung up from the other party, the RTSP stream is resumed on the GSC3570.

The user can also open the door if connected to an access control device without a built-in camera (e.g.: GDS3705).

NAT Settings

If the devices are kept within a private network behind a Firewall, we recommend using STUN Server. The following settings are useful in the STUN Server scenario:

STUN Server

Under Settings🡪General Settings, enter a STUN Server IP (or FQDN) that you may have, or look up a free public STUN Server on the internet and enter it on this field. If using Public IP, keep this field blank.

Use Random Ports

It is under Settings🡪General Settings. This setting depends on your network settings. When set to “Yes”, it will force random generation of both the local SIP and RTP ports. This is usually necessary when multiple GSCs are behind the same NAT. If using a Public IP address, set this parameter to “No”.

NAT Traversal

It is under Accounts X🡪Network Settings. Default setting is “No”. Enable the device to use NAT traversal when it is behind firewall on a private network. Select Keep-Alive, Auto, STUN (with STUN server path configured too) or other option according to the network setting.

Dial Plan Configuration

Dial plan sets the rules to manage outgoing calls, to allow or block some type of calls or change the number format before dialing out. Users can configure dial plan rules through a simple and well-designed interface under menu “Account X 🡪 Dial Plan”.

For explanation purposes, we will be using the dial plan user interface.

The current interface features are as follow:

Name: Users can name their dial plans for identification.
Rule: The rules can be typed out separately or in combination with “Type”
Type: We now support the following types.
1. Pattern: The general rule and it will not change the dial plan you configured.
2. Block: The rules you set in combination with this type will be blocked.
3. Dial Now: The rules you set in combination with this type will be dialed out once the DTMF matches the Dial Plan.
4. Prefix: The rules you set in combination with this type will include configured prefix automatically. If Replaced was set, your used prefix will replace the “Replaced” value. For example: If Dialed 3456, the DTMF will send 123456. See configuration below.
1. Second tone: The rules you set in combination with this type will play second tone if matching the Trigger.
Automatically update the configured data to the Dial Plan in Call Settings.
Dial Plan Verification.

Notes

This feature is not supported by config files (both .xml and .txt).
Users can increase or decrease the priority of each Pattern by pressing to move it up and to move it down.

Edit contacts

Users can navigate under the web GUI menu « Directory 🡪Contacts » and edit all the related settings to each contact. The following fields are available for configuration:

fw.mycompany.com

There are two ways to setup a software upgrade server: The LCD Menu or the Web Configuration Interface.

Follow the steps below to configure the upgrade server path via LCD menu:

Press MENU button and navigate to System.
In the System options, tap System Updates.
Click Update now.

Upgrade via Web GUI

Open a web browser on PC and enter the IP address of the GSC3570. Then, login with the administrator username and password. Go to Maintenance🡪Upgrade and Provisioning page, enter the IP address or the FQDN for the upgrade server in “Firmware Server Path” field and choose to upgrade via TFTP or HTTP/HTTPS or FTP/FTPS. Update the change by clicking the “Save and Apply” button. Then “Reboot” or power cycle the GSC3570 to update the new firmware.

When upgrading starts, the screen will show upgrading progress. When done you will see the GSC3570 restart again. Please do not interrupt or power cycle the GSC3570 when the upgrading process is on.

Firmware upgrading takes around 60 seconds in a controlled LAN or 5-10 minutes over the Internet. We recommend completing firmware upgrades in a controlled LAN environment whenever possible.

No Local TFTP/FTP/HTTP Servers

For users that would like to use remote upgrading without a local TFTP/FTP/HTTP server, Grandstream offers a NAT-friendly HTTP server. This enables users to download the latest software upgrades for their GSC3570 via this server. Please refer to the webpage:

https://www.grandstream.com/support/firmware

Alternatively, users can download a free TFTP, FTP or HTTP server and conduct a local firmware upgrade. A free window version TFTP server is available for download from:

http://www.solarwinds.com/products/freetools/free_tftp_server.aspx

http://tftpd32.jounin.net/.

Instructions for local firmware upgrade via TFTP:

Unzip the firmware files and put all of them in the root directory of the TFTP server.
Connect the PC running the TFTP server and the GSC3570 to the same LAN segment.
Launch the TFTP server and go to the File menu🡪Configure🡪Security to change the TFTP server’s default setting from “Receive Only” to “Transmit Only” for the firmware upgrade.
Start the TFTP server and configure the TFTP server in the GSC3570’s web configuration interface.
Configure the Firmware Server Path to the IP address of the PC.
Update the changes and reboot the GSC3570.

End users can also choose to download a free HTTP server from http://httpd.apache.org/ or use

Microsoft IIS web server.

Configuration File Download

Grandstream SIP Devices can be configured via the Web Interface as well as via a Configuration File (binary or XML) through TFTP, FTP/FTPS or HTTP/HTTPS. The “Config Server Path” is the TFTP, FTP/FTPS or HTTP/HTTPS server path for the configuration file.
It needs to be set to a valid URL, either in FQDN or IP address format. The “Config Server Path” can be the same or different from the “Firmware Server Path”.

A configuration parameter is associated with each field in the web configuration page. A parameter consists of a Capital letter P and 2 to 5-digit numeric numbers. i.e., P2 is associated with the “New Password” in the Web GUI🡪Maintenance🡪Web Access page🡪Admin Password. For a detailed parameter list, please refer to the corresponding configuration template.

When the GSC3570 boots up or reboots, it will issue a request to download a configuration file named “cfgxxxxxxxxxxxx” followed by an XML file named “cfgxxxxxxxxxxxx.xml”, where “xxxxxxxxxxxx” is the MAC address of the GSC3570, i.e., “cfg000b820102ab” and “cfg000b820102ab.xml”. If the download of “cfgxxxxxxxxxxxx.xml” file is not successful, the GSC3570 will issue a request to download a specific model configuration file “cfg<model>.xml”, where <model> is the GSC3570 model, i.e., “cfgGSC3570.xml” for the GSC3570, “cfgGSC3570” for the GSC3570. If this file is not available, the GSC3570 will issue a request to download the generic “cfg.xml” file. The configuration file name should be in lower case letters.

For more details on XML provisioning, please refer to:

https://documentation.grandstream.com/knowledge-base/sip-device-provisioning-guide/

No Touch Provisioning

After the GSC3570 sends, config file request to the BroadSoft provisioning server via HTTP/HTTPS, if the provisioning server responds “401 Unauthorized” asking for authentication, the GSC3570’s LCD will prompt a window for user to enter username and password. Once correct username and password are entered, the GSC3570 will send config file request again with authentication. Then the GSC3570 will receive the config file to download and get provisioned automatically.

Besides manually entering the username and password in LCD prompt, users can save the login credentials for provisioning process as well. The username and password configuration are under GSC3570’s web UI🡪Maintenance🡪Upgrade and provisioning page: “HTTP/HTTPS Username” and “HTTP/HTTPS Password”. If the saved username and password saved are correct, login window will be skipped. Otherwise, login window will be popped up to prompt users to enter correct username and password again.
