What is the Grandstream UCM6202 and how does it work?

The Grandstream UCM6202 VoIP PBX uses analog phone lines to place and receive phone calls. Since the device supports SIP (Session Initiation Protocol), it can be used by WIN-911 as an alternative to TAPI modems anywhere analog phone lines are available to make phone calls. 

WIN-911 interfaces with the UCM using a VoIP connection, the UCM then routes the call to the attached analog line. The UCM device must be on the same subnet as WIN-911 and does not require an internet connection.  

1. Grandstream UCM6202 Setup Guide For Devices Purchased From WIN-911

If you did not purchase the Grandstream from WIN-911 then you will have to follow a different set of instructions. The Grandstream is available for purchase directly from WIN-911 using part number WIN-911/IPPBX. The device has been pre-configured for use with WIN-911 with one phone line, however, you still need to complete 3 basic steps:

1.    Set your static IP address

2.    Set Date/Time settings

3.    Configure WIN-911 settings

A 10-minute overview and configuration video is available on the WIN-911 Software YouTube channel.

Requirement: You must be running WIN-911 3.19.9 or higher, with the configured delay in section "G." of this document, to use the Grandstream UCM6202. 

A. Connecting the UCM6202

  1. Connect one end of an Ethernet cable into the WAN port of the UCM6202, and the other end into your switch or directly into the WIN-911 machine.
  2. Connect the 12V DC power adapter into the 12V DC power jack on the back of the UCM6202. Insert the main plug of the power adapter into an appropriate surge-protected AC power outlet. 
  3. Wait for the UCM6202 to boot up. The front LCD display will show the UCM’s hardware information when the boot process is completed. 
  4. Once the UCM6202 is successfully connected to your network via the WAN port, the Network LED indicator on the front of the device will be lit green, and an IP address will be shown on the LCD display. Take note of the IP address, you will need it to access the Web GUI.
  5. Connect your phone line from the wall jack to the FXO1 port. Do NOT use the FXS ports.

B. Accessing Web GUI

The Grandstream is configured via a Web GUI interface after the device has booted, you should have an IP address that can be used to access it.

1. Open a web browser and enter the IP address into the address bar in the following format: https://ipaddress:8089 (The IP address is displayed on the LCD screen of the Grandstream)

2. Depending on your browser, you may receive a warning about the security certificate. You can ignore this warning and continue to the website. Here is an example of the warning in IE.


3. After the portal loads, enter the default credentials.

Username: admin
Password: (see label on the bottom of the device for the default password)

4. You should now be logged into the Web GUI and you can begin configuring the device.

C. Grandstream Configuration

We strongly suggest setting a static IP address for the device. Please be aware that it is possible for an IP address to change when using DHCP. You may need to work with your IT team to arrange a static IP address that can be assigned to the device.

  • Congratulations, you have successfully configured WIN-911 to use the Grandstream UCM6202.


G. Additional Settings
Configure Phone Call Delay

In some environments, when placing back to back phone calls, it is possible for the Grandstream to signal to WIN-911 that it is ready to accept the next call before it has disconnected from the analog phone line. When this occurs, the next call that is placed will fail. We've added a configurable delay that is placed between all phone calls. The delay is configured in the WIN-911 Voice Runtime configuration file. Use the instructions below to add a 10-second delay between calls.   

  • Open File Explorer and Browse to C:\Program Files (x86)\WIN-911 Software\WIN-911 Enterprise\Voice 
  • Open WIN911.Notifier.Voice.Runtime.exe.config in Notepad
  • Find the <appSettings> section and paste the following key - as shown above.
     <add key="CallDelaySeconds" value="10"/>
  • Save the config file, open your Windows "Services" and restart the WIN-911 Voice Runtime service.
