Configure softphone with Fastwyre SIP Account

First, click the main menu button in the top-left corner of main window.

Choose SIP Accounts in the left window:

Click Add Account button:

Enter your SIP account credentials you got from Fastwyre:

Account name — name it somehow
Register on startup — program does SIP registration for this account if you tick it. If no, the program will not register on a SIP server, so you might not be able to place or receive calls.
SIP server — SIP server hostname or IP address. Program uses 5060 port to connect a SIP server by default. You can define other port using that format: sipserver:5061.
Login — your login
Password — your password
Display name — the name that a callee will see
Authorization name — program uses Login for authorization if this field is empty
Domain — SIP domain
SIP proxy — SIP proxy

6. Click Test Connection button. You'll see the Successful registration message if Softphone.Pro can register on a SIP server.

7. Click Save button to save your SIP account settings. Why not to make the first call? :)
