Adding a SIP Trunk
Use the below step-by-step guide to add and configure your SIP Trunks
- To get started, navigate to the SIP Trunk section on the left-hand navigation bar.
- Select the "SIP Trunks" tab
- Click the "Add SIP Trunk" button
Name your SIP Trunk
Give your SIP Trunk a friendly name using letters, spaces, and numbers. This name will appear under the "Usage" section in your monthly invoice's "Account ID" column.
- Special characters are not accepted.
- Max name length allowed length is 116 characters
Give your SIP Trunk a subdomain using up to 24 alphanumeric characters.
Select how you would like to terminate your outgoing traffic (for example, to MS Teams or Regular SIP Trunk).
- Enter your Username and Password
- Ensure that the username matches the From or To header users.
- Enter one or more required IP Addresses (es)
- If this is a shared platform, please provide additional information for authentication, such as the SIP Header or username/secret on top of the IP address.
Not everyone can support Basic Authentication from a shared platform. If that's the case, you can use SIP Header Authentication. This means you can add a special header and value to the message to prove the message is yours.
- Header Name: Add a special header name for the SIP invite
- Header Value: Add the special header value for the SIP invite
- Protocol: Select your ideal transport protocol
SIP Invite Message Examples: Consider the following SIP message as an example
INVITE sip:+email@example.com SIP/2.0
CSEQ: 1 INVITE
From: “Alice” <sip:+ firstname.lastname@example.org>
To: Bob <sip:+email@example.com>
Date: Wed, 14 Jul 2021 17:58:47 GMT

Downloading SIP URI TLS Certificate
Transport Layer Security (TLS) certificates, also known as Secure Sockets Layer (SSL), work the same as HTTPS and are crucial for securing internet browser connections through data encryptions. Like HTTPS, the secure web certificate is sent when a browser tries to connect using TLS. You can configure and manage the TLS/SRTP within your AVOXI Genius portal as a customer. Certificates are used for authentication and encryption.
An SSL (TLS) certificate for trunk-production-us1.avoxi.com is used for calls from the user to the AVOXI Genius platform and peer.avoxi.io for calls leaving AVOXI Genius. If you are running a modern operating system for your PBX, you shouldn't need to load anything extra to get a TLS connection to work, but we do offer the certificate file for edge cases.
You can download the certificate file from your AVOXI Genius tenant using the following steps.
- Log into Genius at genius.avoxi.com.
- Navigate to the SIP Trunks section located on the left-hand navigation bar.
- Click on the SIP URIs tab.
- Select the three buttons located to the right of the "+Add" button
Click on the "Download SIP URI TLS Certificate."
Calls will only record if the call recording feature has been enabled at an organizational level. As an Administrator, you can easily manage your business call recording settings within your online platform. Use the following self-help guide to turn your recording on/off and manage retention settings. When deleting a SIP Trunk, this will not delete the call recordings.
