You can read can't you? What part of "'SetupTransfer' is not supported by the device" is difficult to understand??

It'll telling you that your modem doesn't support transferring calls.

I can read but the problem is, this device is mobile phone. So in general we know that it can transfer call,but still i am facing the problem.

It doesn't support it in a method that TAPI supports!

Let me know any better modem which support all TAPI function

No idea. Never use them and never will.
