Tips for Configuring a Grandstream VoIP ATA
Trihedral has no relationship with Grandstream Networks. The following is offered as a service to our customers who are attempting to configure a Grandstream HT813 for voice calling with the VTScada Alarm Notification System.
Support for Grandstream products can be offered only by Grandstream Networks, not by Trihedral.
The Grandstream HT813 has been used successfully by many customers. The following information may be helpful when configuring yours. It may not be complete for your specific situation.
Preparation:
- Ensure that you have a working phone line.
(A standard phone should produce a dial tone when connected to the line you intend to use.) - If you intend to configure the Alarm Notification System to accept incoming phone calls, ensure that you know the number assigned to that phone line.
- Configure a static IP address on your network for use by the Grandstream VoIP ATA.
This is likely to require the cooperation of your IT department or Internet Provider.
Have that address ready for the following steps. You will also need the matching gateway address. - On the Grandstream VoIP ATA, ensure that analog phone line is plugged into the FXO port. VTScada does not use the FXS port.
- Also on the Grandstream VoIP ATA, ensure that the Ethernet cable is plugged into the network LAN port, not the network WAN port.
- Connect the other end of the Ethernet cable to your VTScada server, or to another computer where the network can be interrupted.
- If not starting with a new device, perform a factory reset by holding in the reset button for 7 seconds.
- Configure VTScada for VoIP as described in Using VoIP for Alarm Notification
(Example follows)
Given a Grandstream at the fictional IP address of 1.1.1.1 and VTScada at the equally fictional address of 2.2.2.2, configuration would be as follows:
Setting Value SIP identity VTScada <sip:vtscada@2.2.2.2> SIP domain 1.1.1.1
Configure the HT813
The HT813 has many configuration settings. Any that are not mentioned here can usually be ignored.
- Open a browser window on the machine connected to the Grandstream ATA and navigate to http://192.168.2.1/
- Sign in to the Admin account (default password, "admin").
- Open the Basic Settings tab of the configuration panel.
- We recommend you set a new password.
The admin password can be changed using the Advanced Settings tab. - In the section, IPv4 Protocol, select "Statically configured as".
- Set your preferred static IP address as configured during preparation.
- Add the default router address, matching the gateway for your static IP address.
- Select a “Device Mode” of WAN Only.
- Change the “Unconditional Call Forward to VOIP” as follows:
- Set a User ID that can be recognized if needed for debugging. (HT813, for example. This is not used by VTScada.)
- Select “Apply”
- Select “Reboot”.
- Reconnect your Internet cable to connect one end to a standard outlet for your network and the other end to the WAN port on the VoIP ATA.
- Following the reboot, point your browser at the new IP address.
- Sign in again.
- There is nothing to configure on the Advanced Settings tab.
- Open the FXS tab.
VTScada does not use the FXS interface but there is a required configuration step here. - Set "Account Active" to "No".
- Set "Local SIP Port" to a value that will not be used, such as "5064".
- Select "Apply".
Do not reboot. - Select the "FXO Port" tab.
- Ensure that "Account Active" is set to "Yes".
- Set "SIP Registration" to "No".
- Set "Local SIP Port" to "5060".
This is the port that VTScada is configured to use in the VoIP account settings. - Set "Number of Rings" to 1
- Set "Wait for Dial Tone" to "Yes".
- The stage method should always be set to 1 for VTScada. If two-stage dialing is required (ex dial 9, pause, dial number) it must be configured in the Application Configuration, alarm tab, under the VoIP settings: Prefix for phone numbers.
- Select "Apply".
Do not reboot.
Your Grandstream VoIP ATA should be ready to place outgoing calls.
