Quick update:
Still no luck in finding a license for IP SIP but I still have some "things going on" on that.
Unfortunately I also don't have the right daughter card on my CD-LTA card to connect analogue trunks. So at this moment my SV8100 is completely useless!
I looked for it on Ebay and found one in Australia.... So now i'm waiting for it to come, Australia-The Netherlands may take some time.

So at this moment i'm busy with getting to know the system, got the voicemail working, MOH/background music, and so on.
