Note: Video walkthrough for ScopTEL IP PBX/Telnyx configuration coming soon. Check back as we update our docs.

1. Configure your SIP channel

In preparation to create your SIP trunk, you may need to modify two settings, depending on your needs.

From your ScopTEL portal, click on Configuration in the top navigation to open the Telephony Settings: Channels section.
From the Telephony Settings: Channels section, click the Channels tab.
In the Channels section, click on the SIP Channel tab.
We're going to edit some of these settings. Click Edit at the bottom of this page.
In the editor, find the Miscellaneous section and edit the following:
1. Enable Session Progress and In-Band Audio: This is used for Asterisk Early Audio with SIP channels. Configure as needed.
2. Enable Premature Media?: Enabling this option will prevent your SIP channel from automatically initiating early media if it receives audio from the incoming channel before there has been a progress indication. Configure as needed.
Click Save.

2. (RECOMMENDED) Configure SIP TLS/SRTP to encrypt call traffic

In this activity, you'll set up encryption for voice traffic over SIP TLS/SRTP.

Note: If you don't want to configure your trunk to use TLS and encrypt call traffic, jump to step 3.

IMPORTANT: In order to complete this step, you'll need to make sure you've activated SIP traffic encryption on your Telnyx Mission Control Portal per your pre-requisite activities.

From your ScopTEL portal, click on Configuration in the top navigation to open the Telephony Settings: Channels section.
From here, click on the SIP Channel tab and provide the following information:
1. Enable support for SIP TLS (secure)?: Check this box
2. Don't verify servers certificate when acting as client?: Check this box.
Click Save.

3. Create a new SIP trunk

In this activity, we're going to create your first SIP trunk through ScopTEL.

From your ScopTEL portal, click on Interfaces in the top navigation to open the Interfaces Manager.
From the Interfaces Manager, click the VoIP Accounts tab.
On the right of this section, click Add a new VoIP Account to open the VoIP accounts configuration utility.
Click on the General tab and provide the following information:
1. Type: SIP
2. Trunk Type: Friend
3. Name: This is your choice. It must be unique and contain ONLY alphanumeric characters. If you want to receive calls on this trunk, you should define the name to be the same as the username. We just chose the generic TelnyxTrunk as an example.
Now click on the Server tab and provide the following information:
1. Username: Your Telnyx account/sub-account username
2. Password: Your Telnyx account/sub-account password
3. Host: sip.telnyx.com
4. Port: 5060
5. Register as User Agent: Check this box
6. Enable TLS registration: (OPTIONAL) If you completed step 2, check this box. Otherwise, leave it unchecked.
7. Contact Extension: Your Telnyx account/sub-account username
Next, click on the Network tab and provide the following information:
1. Transport mode: Choose UDP, TCP, or both UNLESS you have created a SIP trunk with TLS. In this case, only check TLS.
2. Insecure: Check the box next to Invite.
And finally, click on the Options tab and provide the following information:
1. DTMF Mode: Automatic (Will use RFC 2833)
2. Send Remote-Party-ID: Check this box
3. Codecs: Select any Telnyx-supported audio and video codecs:
  
  Supported audio codecs:
  1. ulaw(g711u)
  2. alaw(g711a)
  3. g722
  4. g729
  Supported video codecs:
  1. H264
4. Disallowed Methods: Check the box next to UPDATE.
Click Add.

4. Create inbound rules

In this activity, you'll set inbound rules which will allow you to receive incoming calls from your Telnyx DIDs that you provisioned as part of your pre-requisite activities.

To create an incoming line, Click Lines in the top-navigation.
In the Lines Manager: Incoming Lines sub-section, click on the Incoming Lines tab.
Click on the Add a new Incoming Line on the right to open the Incoming Lines form.
Click on the General tab and provide the following information:
1. Extension (DNIS): Your Telnyx DID number that you provisioned as part of your pre-requisite activities.
2. Trunk: Use the dropdown menu to select the trunk you just created.
Click Add.

That's it! You've now configured a trunk to work between ScopTEL IP PBX and Telnyx!
