I have a working right now 648 2 cabinet with over 200 various type phones mostly m32 some large ACD sets .6 pri cards ,14 DVA's fully loaded options ...we bought a new PBX and don't need this work horse, any one have any thoughts...I know the PRI's are very hard to come by and a bit pricey but with a whole system probably worth a look....IM me or email...Thx
