What are the Sip Connection Types?

We offer four different authentication types to register your switch to ours. This article will show you how to configure these types within the Mission Control Portal and explain the various settings that SIP Connections have.

SIP Connection Registration Types Explained

Deciding on what registration type to use depends on your use case. As a rule of thumb, a credential-based connection is used if you have a dynamic public IP address. If you have a static IP address, then you can use an IP-based connection instead.

Below are guides on how to setup the following connection types:

  • Credential-based Authentication

  • IP-based Authentication

  • FDQN-based Authentication

A username and password will automatically be generated but you can change the credentials via the Authentication & Routing Configuration section within the SIP connection's settings. It is highly recommended that you choose a strong password.

This connection type is slightly different as it has an inbound setting and an outbound setting.

In the inbound settings, choose your FQDN type (for most users this will be A) and enter your Fully Qualified Domain Name in the input box. Click Save FQDN to add the address.

In the outbound settings, choose either Credentials or IP Address, and configure using the guides above.

4. Click Save & Finish Editing or your FQDN will not be saved

Save and Finish Editing button.

Note: You can assign multiple FQDN addresses on the Inbound section and multiple IP addresses on the Outbound section to a single FQDN registered connection. You can change the routing priority and routing method in the connection settings.

Where can I find the connection id?

Once a connection is created, you can find the unique connection id just below the settings sub tab of the SIP Connection as seen below:

Take a look at our SIP Connections API if you want to programmatically update the SIP Connection settings.

How do I deactivate or disable my SIP Connection?

To deactivate or disable your SIP Connection visit the SIP Connections page and click the toggle under the "status" column. This will deactivate the SIP Connection which will mean inbound calls and outbound calls will not be processed. See this image below for reference.
