Using VTrunk with Gateways
This page has specific instructions for using VTrunk with gateways such as the TCB-IP2 and MSAT-IP. See Using VTrunk for background and other related information.
Before Enabling VTrunk
VoIP connections between IP2s are generally managed using the LinkTDS software, especially when using VTrunk. If it is possible to connect the IP2s and the computer running LinkTDS to the same LAN at least temporarily, it may be helpful for testing everything else before enabling VTrunk. See .
Setting up VTrunk
The following instructions describe the steps needed to configure two IP2 units to communicate through VTrunk (the MSAT-IP is very similar, but may require a more recent firmware version).
- Download RCI/firmware version 5.50 or later here and follow the installation instructions from TCB-IP2 Software Updates to install the updated firmware on each IP2.
- Also on each IP2:
- From RCI's TCB-IP2 Settings menu select "VTrunk Settings". On the VTrunk Settings form that appears, check the "Enable VTrunk" checkbox then click the "Save Settings and Reset" button.
- When RCI reconnects after the IP2 resets, again select "VTrunk Settings" from the menu. It may (if the IP2 has not previously been registered with VTrunk) display a registration code and instruct you to go to http://www.vtrunk.net to register the unit. If you do not already have an account, you can create one there.
- After logging onto the web site, click on the "Devices" tab in the top right, then click the "New Device" button (on the left, near the top). Enter the registration code shown in RCI and click the "Register" button. It should then prompt you for a name (choose a name to identify that unit). If it does not, click the "Devices" tab in the top right again, then "Register New" and try again.
- If you get a message about the registration code being invalid, make sure the IP2 has a connection to the Internet and reboot it. It must be able to upload its registration code to the VTrunk.net website before you will be able to register it.
- After registering the IP2 on the web site, from RCI again click the "Save Settings and Reset" button. After the IP2 resets and RCI reconnects, once again select "VTrunk Settings" and check the "VTrunk Status" in the lower-left corner; all four checkboxes should be checked.
- Repeat for any other IP2 units.
Linking two units using VTrunk
- With both IP2 units connected to the same network, set up a multicast VoIP connection between them. This is most easily done using LinkTDS:
- Configure LinkTDS to use VTrunk, as described here: Using VTrunk with LinkTDS.
- A LinkTDS registration key will not be needed to set up a single connection between a pair of IP2s, though it may be to accomplish more complex tasks.
- Press CTRL-R to display the resource discovery panel. You should see a list of ten "patches". Within about ten seconds, you should also see four (two for each IP2) radio interfaces. Two of them should have the "unique names" you assigned to them using RCI in one of the steps above. Click and drag widgets for those two onto the center area of the screen (you can rearrange them afterward by right-clicking and dragging them).
- Near the bottom of each of those widgets you will find a red "X" (crosslink icon). Click on it and select "Patch 1". Then click on the gear on each widget and select "Save Settings".
- Cause the receiver connected to one of the IP2s to go active (such as by transmitting to it using another radio). A green receiver-activity indicator will appear in the widget representing that radio in LinkTDS. A red transmitter-activity indicator will also light on the other widget indicating that VoIP audio has been passed from one IP2 to the other and is being re-transmitted there.
- Move one of the IP2s to another network connection.
- As long as it can access the Internet, everything should work as before.
