Note: Video walkthrough for Grandstream GXP/Telnyx configuration coming soon. Check back as we update our docs.
1. Log into your Grandstream web UI
All the configuration you'll need to do will take place on the web UI, which acts as an interface between you and your Grandstream device. You can access the web UI via the device's IP address. We'll find that, then use it to log in.
The IP address used to access the web UI depends on where the user’s computer is connected.
If the computer is connected to the same switch/router that the UCM6200 series WAN port is connected, then browse to the IP address that is displayed on the UCM6200 series LCD. This address is the WAN IP.
If the computer is connected to the LAN side of the UCM6200 series, then users would browse to the default IP of the UCM6200 series which is 192.168.2.1.
If connected successfully, the UCM6200 series login page. Out of the box, your device will have the following default credentials:
HOWEVER: Units manufactured starting January 2017 have a unique random password printed on the sticker located on the back of the unit. It is highly recommended to change the default password after logging in for the first time. Older units have default password admin.
2. Configure SIP trunk
In the left-hand navigation, expand Extension/Trunk and click VoIP Trunks in the sub-menu.
Click Add SIP trunk and fill in the required information:
Type: Register SIP Trunk
Provider Name: Telnyx
Select host Name: 22.214.171.124
3. Create an inbound route
When a call comes in from the outside, it'll need to be directed from sip.telnyx.com to the phone extension you ultimately want it to go, such as a user extension or an IVR extension.
In this section, we'll configure our own inbound routes.
In the left-hand navigation, expand Extension/Trunk and click Inbound Routes in the sub-menu.
Select the trunk and then click add on the left hand side of the screen underneath Inbound Routes.
Enter in the patterns which apply to this inbound rule. This is a good article to understand how to correctly format the pattern.
In default mode select your default destination as Extension.
Click Save in the top right-hand corner of the screen.
4. Create outbound route
Outbound routing is a set of rules that tells FreePBX which Telnyx trunk to use for any given outbound call. Having multiple trunks allows you to control cost by routing calls over the least costly trunk for a particular call. Outbound routes are used to specify what numbers are allowed to go out a particular route.
You will want to make sure you define routes for all types of calls. Not defining a route can leave your users frustrated when they need to make an important call.
In the left-hand navigation, expand Extension/Trunk and click Outbound Routes in the sub-menu.
Name the calling rule name to something of your choice and add the number pattern.
Set your privilege level to match the service plan in the outbound settings on your Telnyx portal.
Select your trunk in the use trunk section
5. Configure an outbound caller ID
Now let's configure your outbound caller ID. Grandstream offers many ways to configure a caller ID on your SIP trunk. This section will demonstrate 3 ways of doing this:
Setting a single global outbound caller ID which will apply to every number on your trunk.
Setting a unique caller ID for every extension on your trunk.
Setting a unique caller ID for every outbound route you create (every extension associated with that route will have the same caller ID)
Note: Before configuring an outbound caller ID, you should be aware of some of the naming conventions standard for caller ID creation:
To enable a global outbound CID:
From the left-hand navigation, expand PBX Settings and click General Settings in the sub-menu.
To enable caller IDs for each extension:
From the left-hand navigation, expand Extension/Trunk and click Extensions in the sub-menu.
Click on the extension you want to assign a caller ID and provide your caller ID in the CallerID Number field.
To enable a caller ID on the outbound route:
From the left-hand navigation, expand Extension/Trunk and click Outbound Routes in the sub-menu.
From here, you can set your caller ID for the entire route in the Outbound Route CID field.
That's it, you've now completed the configuration of Grandstream and can now make and receive calls by using Telnyx as your SIP provider!
