Hi All, Have a client with an existing (and quite proprietary, cheesy) NEC IP PBX system (NEC SV8100 NEC CD-16DLCA Station Blade with DT300 ip phones). Their current setup is keeps failing and costing them nearly a $1,000 per month between the PR-T1 line and phone minutes from Verizon. Taking a shot on the dark here, but does anyone know if there is any way at all to make this compatible with 3CX and a SIP trunk provider like NexVortex? Doesn't seem so as NEC appears proprietary, but figured I'd take a chance and post here. Any help would be greatly appreciated. Thank you.
