GSC3574/75 Wiring Connection
Warning
Please disconnect the power supply during wiring, disassembly, and other operations. Do not operate with electricity on.
Alarm IN/OUT PINS
Alarm_IN pins are used to connect external sensors or detectors that detect events like motion, door/window openings, or smoke. These pins trigger the control station when an alarm condition is detected.
Alarm_Out pins are used to connect to external devices such as sirens, lights, or notification systems. When the control station detects an alarm condition, it sends a signal through these pins to activate the connected external devices.
The figure below shows an illustration of the Circuit for Alarm_In and Alarm_Out.
Alarm InOut Circuit
Notes:
The Alarm_In and Alarm_Out circuit for the GSC3574/75 should meet the following requirement:
Alarm Input
9V<Vin<15V, PINs (1.02KΩ)
Alarm Output
125VAC/0.5A, 30VDC/2A, Normal Open, PINs
In the Alarm_In circuit, if there is any voltage change between 9V and 15V, as specified in the table above, the GSC3574/75 Alarm_In port will detect it and trigger the action and event.
Higher voltage and wrong polarity connections are prohibited because this will damage the devices.
There is also an important distinction between the two types of Alarm_IN, Passive, and Active:
Alarm In (Active): This type of input involves sensors or detectors that actively send a signal to the control station when a specific event or condition is detected. For example, a motion sensor might actively trigger the alarm in (active) input when it detects movement in its monitored area. These sensors require power and actively transmit signals when they detect something. The pins that are responsible for Alarm In (Active) in the GSC3574/75 are IN7+/IN7- and IN8+/IN8-
Alarm In (Passive): This refers to inputs that respond to changes in their environment without actively transmitting signals to the control station. These inputs include simple contact sensors on doors or windows. They do not actively send signals but instead rely on changes in their status (e.g., open/close) to trigger the alarm input. They don’t require power to send signals, but may need power for any internal mechanisms like switches or sensors. The pins that are responsible for Alarm In (Passive) in the GSC3574/75 are IN1/IN2/IN3/IN4/IN5/IN6.
The GSC3574/75 supports Wi-Fi technology and can be connected from the LCD or the WEB UI configuration parameters.

Specifies the mechanism to transmit DTMF digits. There are 3 supported modes:
In audio: DTMF is combined in the audio signal (not very reliable with low-bit-rate codecs).
RFC2833 sends DTMF with RTP packet. Users can check the RTP packet to see the DTMFs sent as well as the number pressed.
SIP INFO uses SIP INFO to carry DTMF.
Default setting is “RFC2833”.
DTMF Payload Type

If set to “Yes”, when silence is detected, a small quantity of VAD packets (instead of audio packets) will be sent during the period of no talking. For codec G.723 and G.729 only.
Default setting is “No”.
Voice Frames Per TX
Configures the number of voice frames transmitted per packet. It is recommended that the IS limit value of Ethernet packet is 1500 bytes or 120 kbps. When configuring this, it should be noted that the “ptime” value for the SDP will change with different configurations here. This value is related to the codec used in the codec table or negotiate the payload type during the actual call. For example, if set to 2 and the first code is G.729, G.711 or G.726, the “ptime” value in the SDP datagram of the INVITE request is 20 ms. If the “Voice Frame/TX” setting exceeds the maximum allowed value, the phone will use and save the maximum allowed value for the selected first codec. It is recommended to use the default setting provided, and incorrect setting may affect voice quality.
The default setting is 2.

test : only string “test” will pass the dial plan check
^ – exclude
[3-5] – any digit of 3, 4, or 5
[147] – any digit of 1, 4, or 7
<2=011> – replace digit 2 with 011 when dialing
| – the OR operand
Example 1: {[369]11 | 1617xxxxxxx}
Allow 311, 611, and 911 or any 11 digit numbers with leading digits 1617;
Example 2: {^1900x+ | <=1617>xxxxxxx}
Block any number of leading digits 1900 or add prefix 1617 for any dialed 7 digit numbers;
Example 3: {1xxx[2-9]xxxxxx | <2=011>x+}
Allows any number with leading digit 1 followed by a 3-digit number, followed by any number between 2 and 9, followed by any 7-digit number OR Allows any length of numbers with leading digit 2, replacing the 2 with 011 when dialed.
Example of a simple dial plan used in a Home/Office in the US: { ^1900x. | <=1617>[2-9]xxxxxx | 1[2-9]xx[2-9]xxxxxx | 011[2-9]x. | [3469]11 }
Explanation of example rule (reading from left to right):
^1900x. – prevents dialing any number started with 1900;
<=1617>[2-9]xxxxxx – allows dialing to local area code (617) numbers by dialing7 numbers and 1617 area code will be added automatically;
1[2-9]xx[2-9]xxxxxx |- allows dialing to any US/Canada Number with 11 digits length;
011[2-9]x – allows international calls starting with 011;
[3469]11 – allows dialing special and emergency numbers 311, 411, 611 and 911.
Note: In some cases, where the user wishes to dial strings such as *123 to activate voice mail or other applications provided by their service provider, the * should be predefined inside the dial plan feature. An example dial plan will be: { *x+ } which allows the user to dial * followed by any length of numbers.
Max length of dial plan is up to 1024 characters.

A defined pattern with certain length using x and + to specify, where x could be any digit from 0 to 9. Samples:
xx+ : at least 2-digit number.
xx : only 2-digit number.
[345]xx: 3-digit number with the leading digit of 3, 4 or 5.
[6-9]xx: 3-digit number with the leading digit from 6 to 9.
Alert Info text
Users could configure the matching rule as certain text (e.g., priority) and select the custom ring tone mapped to it. The custom ring tone will be used if the phone receives SIP INVITE with Alert-Info header in the following format: Alert-Info: <http://127.0.0.1>; info=priority When the incoming caller ID or Alert Info matches one of the 10 rules, the phone will ring with the associated ringtone.
Note: Beginning with firmware version 1.0.3.98, a new feature was introduced that enables the use of a ringtone stream via a remote URL. The functionality of this feature works as follows: the following audio file named test.wav is uploaded onto an HTTP server and the remote URL is “http://192.168.5.165:8080/test.wav;info=ring3”, the IP phone then attempts to use the provided URL first to play the ringtone. If the URL is not functional for some reason, it will then use the info=ring3 parameter, as the default ringtone.

UPGRADING AND PROVISIONING
Warning
Firmware version 1.0.1.17 is the last release supporting Android 13.
Before upgrading to Android 14, ensure the device is running firmware version 1.0.1.17, which introduces the Backup and Restore feature. Back up data by following the steps in the Backup and Restore section. Upgrading the OS without a backup will result in total data loss.
Once the device is upgraded to Android 14, it cannot be downgraded back to Android 13.
Firmware version 1.0.3.1 is the first release based on Android 14.
After upgrading to 1.0.3.1, a factory reset is required to correctly initialize all parameters.
The GSC3574/75 can be upgraded via TFTP / HTTP / HTTPS by configuring the URL/IP Address for the TFTP / HTTP / HTTPS server and selecting a download method. Configure a valid URL for TFTP or HTTP/HTTPS; the server’s name can be a FQDN or an IP address.
There are two ways to set up a software upgrade server: The LCD Menu or the Web Configuration Interface.
Upgrade via LCD Menu
Follow the steps below to upgrade the GSC3574/75 automatically using the configuration server path :
Navigate to Settings → Advanced → System Updates.

LCD upgrade
Upgrade via Web GUI
Open a web browser on your PC and enter the IP address of the GSC3574/75. Then, log in with the administrator username and password. Go to the Maintenance → Upgrade → Firmware page, enter the IP address or the FQDN for the upgrade server in the “Firmware Server Path” field, and choose to upgrade via TFTP or HTTP/HTTPS. Update the change by clicking the “Save and Apply” button. Then, “Reboot” or power cycle the GSC3574/75 to update the new firmware.
When upgrading starts, the screen will show the upgrading progress. When done you will see the GSC3574/75 restart again. Please do not interrupt or power cycle the GSC3574/75 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.
For more information on the firmware upgrade methods, please check the Guide:
For users who would like to use remote upgrading without a local TFTP/HTTP/HTTPS server, Grandstream offers a NAT-friendly HTTP server. This enables users to download the latest software upgrades for their GSC3574/75 via this server. Please refer to the webpage:
Alternatively, users can download a free TFTP, or HTTP server and conduct a local firmware upgrade. A free window version TFTP server is available for download from:
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 GSC3574/75 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 GSC3574/75’s web configuration interface.
Configure the Firmware Server Path to the IP address of the PC.
Update the changes and reboot the GSC3574/75.
End users can also choose to download a free HTTP server from http://httpd.apache.org/ or use a Microsoft IIS web server.
Configuration File Download
Grandstream SIP Devices can be configured via the Web Interface as well as via an XML Configuration File through TFTP, or HTTP/HTTPS. The “Config Server Path” is the TFTP 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 numbers. i.e., P36 is associated with the “SIP server” in the Web GUI → Account Settings →Account 1 →General Settings, or an alias. For a detailed parameter list, please refer to the corresponding configuration template.
When the GSC3574/75 boots up or reboots, it will issue a request to download a configuration file named “cfgxxxxxxxxxxxx.xml”, where “xxxxxxxxxxxx” is the MAC address of the GSC3574/75, i.e., “cfgc074ad0102ab.xml”. If the download of “cfgxxxxxxxxxxxx.xml” file is not successful, the GSC3574/75 will issue a request to download a specific model configuration file “cfg<model>.xml”, where <model> is the GSC3574/75 model, i.e., “cfggsc3574.xml” for the GSC3574, “cfggsc3575.xml” for the GSC3575. If this file is not available, the GSC3574/75 will issue a request to download the generic “cfg.xml” file. The configuration file name should be in lowercase letters.
For more details on XML provisioning, please refer to:
After the GSC3574/75 sends the config file request to the provisioning server via HTTP/HTTPS. If the provisioning server responds “401 Unauthorized” asking for authentication, the GSC3574/75’s LCD will prompt a window for the user to enter the username and password. Once the correct username and password are entered, the GSC3574/75 will send the config file request again with authentication. Then the GSC3574/75 will receive the config file to download and get provisioned automatically.
Besides manually entering the username and password in the LCD prompt, users can save the login credentials for the provisioning process as well. The username and password configuration are under GSC3574/75’s web UI → Maintenance → Upgrade and provisioning page: “HTTP/HTTPS Username” and “HTTP/HTTPS Password”. If the saved username and password are correct, the login window will be skipped. Otherwise, a login window will pop up to prompt users to enter the correct username and password again.
