What USB phone are you using? Are you using the latest version of PhonerLite? Do you really have selected the sound devices explicitly? If you are using "Default" sound device in PhonerLite, it won't work.

Are you using Win7 in 32 or 64 bit version? I will check that soon - I have to search for that device somewhere in the basement.

OK, I checked that now here too. First try after plug the device was NOT successful. The device names are different. After reboot my Win7 it works as expected. When selecting the capturing device in PhonerLite (2- USB Audio Device) it works. Before the reboot the device name was different - sorry forgot the name.
Can you please check if it the same for you?

So, i did what you said, but it didn't work. (
Situation is the same. Looks like it's because of my windows's language. I want to solve this problem veeeery veeeeery much, so if I can possibly help you somehow, just let me know.

And one more thing. there are unused buttons on the phone, is it possible to bind them to some actions? For example, "redial" would dial last called number, and "flash" would transfer active call? If it is possible, that would be just perfect.

Thank you again.

This is the output:

In PhonerLite capture (mic) device is called "Микрофон (USB Audio Device)" or "Микрофон (2- USB Audio Device)" depending on which port it's connected to.

Yes, I installed version from your site.
Programs like Zoiper hook the phone on win7, so i don't know what's the problem. I can try to install Phoner on english or german win7 on VM and test the phone if you're interested. maybe we could find a way to solve this.

Yes, i do have those dll's. And yes, Phoner is the only application, trying to access the phone. 
Maybe it's because device named diffirent? ("USB Audio Device" in XP and "Микрофон (USB Audio Device)" in win7? Or it is doesn't matter?

Or maybe you could make some kind of function to allow force-hook the phone, if it's not connected automaticly?
