The one thing Avaya are not prepared to do, is do an R&D spend to create a new Processor to replace the CPPM or investigate a server based VM solution to replace it. The whole issue of supporting the CS1000E and its derivatives, was that the manufacturing source for components was drying up.. no one makes stuff that old anymore (unfortunately), that there were too many ancillary systems with the same forward looking issues (CallPilot in cabinet, MIRAN, MICB) and the unwillingness to continue two streams of CC for a LAN connected service and a unique but fit for purpose Meridian solution. Besides the problem of memory restrictions within the CPPM card, Avaya want to get away from hardware responsible to software and profit.
HOWEVER, one group of individuals have ALREADY overcome all of these issues for the future.. been doing so from virtually the day Nortel ceased trading, and they are Ex-Nortel.. e-MetroTel produce a softswitch to replace the core of CS1000 solutions up to and including multi-group. So the customer can keep all of their existing hardware, source replacement cab cards from the vast source of the second user market, integrate into any SIP solution going and have a manufacture, software developer, that will keep the solution going for as long as the very reliable hardware stays up.
A couple of things in the customers minds: is the offer Avaya making for CS1K holders attractive enough, can the offer be viewed as future proofed, does the alternative e-MetroTel option have enough support and life to make it viable or shall we bite the bullet, write off the capex expended and go for a new cloud subscription option with another vendor (or Avayas version of same)?
