Configuring SignalWire and Linphone

The first step is to create a SIP Endpoint and point a SignalWire purchased number to that endpoint. When creating this endpoint, keep the default Encryption and default Codecs/Ciphers.

We will now use the details of the sip endpoint we created to connect to Linphone. If you haven't already downloaded Linphone, check out some getting started guides on their public Linphone wiki!

Under the hamburger menu in the upper right click Preferences then Add Account.

Next, we will need to go through the following settings pages in order to specify the correct information. Make sure to disable Enable AVPF and Enable ICE or it will not work correctly.

SIP Address and SIP Server Address are created using the SIP domain generated after creating a SIP endpoint in the first step

If you get the error Unable to Authenticate. Please verify your password., enter your SIP endpoint password and click Login.
