We have test tools that require us to call SIP addresses like localhost:5061.

I used to use SJPhone on Windows XP, and an older version of X-lite, which both worked fine, and didn't require the SIP phone to be registered with a SIP proxy.

I have just upgraded to Windows 7 and SJPhone doesn't seem to work any more (see forum here for others with the problem) - it says "No sound input device / No sound output device" at startup.

I have tried a range of other softphones (X-lite 3, X-lite 4, Zoiper, 3CX), but I can't seem to find any that will install on Windows 7 and will let me call a SIP address like localhost:5061. It might be that I just don't know how to configure these phones to do it...

Update: I didn't make any changes but SJPhone started working recently on my Windows 7 machine. I had definitely tried rebooting before, so I don't think that was the reason.

I believe Blink will do exactly what you want.

I used it for testing in the way you mentioned when I wanted to get type SIP addresses working on my Freeswitch server.

Apparently the Ekiga softphone from supports this on Windows 7. You don’t need to register with this phone, and can call an arbitrary SIP server using the syntax:


I've also heard that a good workaround is to install Virtual Server on your Windows 7 box, and run SJPhone inside an XP virtual machine.
