Is it possible with the standard OS on a Quadro to provide the "host" end of a Sip-Trunk connection to allow a "downstream" PBX (Quadro or otherwise!) to connect to it? I don't want to become an ITSP overnight but I would like to hook in a secondary PBX for test purposes - and ideally the second PBX would see this facility in an identical fashion to an ITSP provided sip trunk account.
Cheers.
