This has probably been asked before,
but i do not know the terms to search frown

Is there a way to connect one of the analog ports on my
Samsung DCS Compact to a VOIP adapter,
the VOIP adapter to internet,
a second VOIP adapter somewhere else on the internet,
and a analog phone to that VOIP adapter.
To let this analog phone call as it was part of my phone system..?

Probably need VPN or Locked IP-address..?
