My first question:

When I checked the code last night for the licenses I found that

libeXosip is a extension to libosip2

and it's under GPL, but mod_exosip is under MPL. How is it possible to

use it then?

This is why exosip is going away and mod_sofia is taking its place.

My second question:

I was asked to do some research on the feasibility of using FreeSwitch

in a commercial product.

My question is:

If some company will make the modules which is using the FreeSwitch Core

and interoperates with

other modules shall that company open the source code of their modules

or that is not necessary?

The MPL allows this but you are encouraged to open source your modules if possible. But its not a requirement.

Shall they provide the source code of the rest of the FreeSwitch code

with the product or they can

refer to freeswitch.org for the source code?

You don't have too.

Is it possible to use FreeSwitch code in commercial products at all or

there is some additional restrictions?

Yep you can and nope their is no additional restrictions. (Read the MPL 1.1)
