Nortel PBX phone system

Used Nortel PBX phone system with 9 working telephone desk units.  Also included is a Nortel network Call Pilot 100 for voice mail services.  The call pilot may have a programming error and may not work.  However the PBX phone system and phone units are in good working order.  The PBX phone system is capable of 10 desk units.  We have upgraded our phone system to a larger network and therefore replaced this system.  All units are being sold as is without a warranty.
