I am trying to setup trial versions of SIP Proxy and Media Proxy on a computer that cannot access internet. I generated license requests and sent them via mail to, but both returned same error:

What should I do to obtain the trial licenses?

Hi Michal,

Thanks for your post. Nice forum name – I like it.

The original “support” email address had to be retired due to all the “low life” spammers out there. :)

I will send you an email that will give you the proper support email address. Go ahead and then forward the license requests to the new address. We will take care of you right away.

I’m not too familiar with your company but from the information on your web site, you look like a company that we would really relish working with.
