IPO is not that bad to learn as I am an old gizzer myself from the Nortel/BCM camp . I signed up with Avaya learning dot com and took couple course on line and got myself an IPO demo kit . We all got day job but I do enjoy break & fix a lot with the demo kit. My clients are moving fast in replacing pretty much all their Partner & CICS once they see that they can fastly expand and save pretty much all their M & T sets . We had couple large job with BCM450 proposal but in the end, all end up with IPO when we inform our clients of the looming date of the EOS of the BCM line . Norstar/Nortel specially CICS/MICS with its legendary durability was hard to beat but we trully feel that it is time to march on with Avaya
newer line of thinking . In all fairness, IPO release 7 is a good effort mainly for the Nortel support. Release 8 should be a bit better on SIP 12xx series set .
