How it works

A Telnyx Elastic SIP Trunk is used to connect your IP-based communications infrastructure to the PSTN, so you can make and receive calls globally with our private IP network. We handle all the complexity in routing calls and delivering crystal clear conversations. To connect your Telnyx numbers to your Grandstream platform we need to establish a SIP interface which is completed in these steps:

1. Set up your Telnyx SIP Trunk Connection.
2. Authenticate your SIP Trunk with Grandstream.
3. Configure your Grandstream profile for Inbound and Outbound calling.

Mission Control Portal - Getting Started

There are four steps needed to set up your Telnyx Mission Control Portal account so that it’s ready to be configured to your PBX phone system, softphone client or softswitch of your choice.

Level 1 Verification:

To complete the below steps, you'll need to be Level 1 verified. Most users will already be Level 1 verified following email confirmation on signup. To check, visit the ‘My Account’ section of your portal account, and navigate to ‘Verifications’. More information on account verification.

Connection Setup

Once you have signed up for a Mission Control account, you need to set up a connection to authenticate your client (Grandstream) with our sip proxy (sip.telnyx.com). We have three authentication types on the portal: Credentials, IP Address and FQDN.

These steps will walk through the setup of a credentials based connection.

1. Go to ‘Connections’ from the side navigation.
2. Click the "+ Add Connection" button near the top right corner of the page.
3. Enter the name you wish to have for your connection.
4. Select "Credentials" as the "Connection Type".
5. A username and password will automatically be generated but you change the credentials by clicking the "edit" button to the left. Please make sure you use strong credentials.
6. Click "Set Credentials".
7. Click "Done".

Note: Once your credential-based Connection is created, you can display the username and password by clicking the eye icon under the "Auth Detail" column.

DIDs

A DID is required in order to receive inbound calls to your client. After you purchase a DID on your account, you'll have to assign the connection you wish to receive inbound calls to.

Outbound Profile

An outbound profile is required in order to make outbound calls. More information on creating an outbound profile and its features.

5. After you have entered the new inbound route then click save in the top right hand side of the screen.

Create Outbound Route

1. Navigate to the outbound routes shown below.
