Very neat installation:

Western Electric 551C KSU + Ascom 2030 PBX + 2x VoIP->ISDN gates

All installed on one wall in my home office room.

System under construction in basement will have:

2x Western Electric 584C panels + Ascom 2050 PBX (bigger) + ISDN gates + BT Link for iPhone integration into 1A2
