Instructions for creating a SIP trunk on your Grandstream GRP 260x device
In this activity, you will:
Pre-Requisites
Ensure that your Telnyx Mission Command Portal is configured properly
Provision your number (Assign it to a SIP connection)
Create a credentials-based connection on your Telnyx Mission Control Portal
RECOMMENDED: Enable TLS to encrypt your traffic
Ensure your phone is on the most current firmware
Connect your device to an ethernet port to establish an internet connection
Use your phone's base or handset to find the device IP address. This IP address will link you to the web portal, where you will complete your configuration. See the Grandstream GRP 260x Series admin guide to find your phone's IP address and obtain the default portal login credentials.
Note that you can also establish a SIP trunk directly from your phone's keypad. You can find field values you'll need below.

The Grandstream GRP 260x web portal has 9 configuration sections. While you may wish to change values across all of these sections, the ones that concern your Telnyx SIP trunk integration are:
Status
Account
Note: The following settings are required to establish a SIP trunk with your Telnyx service. A full list of settings is available here. |
1. Configure a Telnyx SIP trunk on your device
In this step, you'll create and register a SIP trunk that will connect your device to your Telnyx account or sub-account.
Navigate to the Account settings screen and use the following settings to configure your SIP trunk:
In the General Settings > Account Register section:Account Active: Set as Yes if you plan to activate your new trunk as soon as it's set up.
Account Name: Choose a name for your account. It will display in the phone's LCD screen.
SIP Server: sip.telnyx.com (For US users. International users see this table.)
Secondary SIP Server: 64.16.250.10 (For US users. International users see this table.)
SIP User ID: The SIP connection username. Learn more here in the Credentials Connection Setup section.
SIP Auth ID: The SIP connection username. Learn more here in the Credentials Connection Setup section.
SIP Auth Password: The SIP connection password. Learn more here in the Credentials Connection Setup section.
Name: This is your caller ID. You can choose whatever you like, but keep in mind the following naming conventions:
Caller ID Name should be in capital letters. This will appears more clearly/visible on some devices.
You must NOT use any special characters, as they will not be displayed. Spaces are allowed.
Some of regular Canadian providers will not show more than 15 characters. We suggest shrinking or adapt your caller ID.
Fallback Expiration: Specifies the duration (in minutes) since failover to the current SIP server or Outbound Proxy before making failback attempts to the primary SIP server or Outbound Proxy.
In the General Settings > Network Settings section:
Outbound Proxy: sip.telnyx.com
Max number of SIP request replies: Sets the maximum number of retries for the device to send requests to the server. In DNS SRV configuration, if the destination address does not respond, all request messages are resent to the same address according to the configured retry times. Valid range: 1-10.
In the SIP Settings > Basic Settings section:
SIP registration: Leave this setting enabled if you want your phone to send SIP Register messages to the proxy/server.
SIP transport: The network protocol used for SIP transport. The default is UDP. If you plan to encrypt traffic, you can choose TLS/TCP, provided you've configured your Telnyx portal to encrypt data.
SIP listening mode: Do you want your phone to listen to multiple SIP protocols? You have the option of choosing:
Dual: If you've selected UDP, phone will also listen for TCP
Dual (Secured): If you're transporting over UDP, phone will also listen for TLS/TCP. If TLS/TCP is selected, phone will also listen for UDP.
Dual (BLF Enforced)
Transport Only (Default)
Local SIP port: UDP will use 5060, TLS/TCP will use 5061
Navigate to the Status page where you can check all your account details.
That's it, you've now completed the configuration of your Grandstream GRP260x device.
