Delay in answer using X-Lite

[infostudi]

Hello, I'm using 3CX v5.0.3752.0.

When I call an extension that is using X-Lite 3.0, after he answers the call, there is a 3-4 seconds delay before the call is established.
In other words, when the other party says "Hello", I still hear the ring tone.
With other softphones (like SJPhone), there is no problem.

Any suggestions? Thanks in advance.
