Well, for those of you who think Avaya doesn't listen to your concerns, allow me to disuade that line of thinking. Take note that a majority of the posts on this thread were from the past 24 hours and the thread has only been alive for 48.
I received a phone call from Avaya this morning. Now, Avaya isn't allowed to post to this (or any) forum as a general rule. However, the conversation I had should help alleviate some of the issues in this thread.
First, 406v2 PCS8 and lower. These units had 16 megs of RAM in them and the newer PCS9 and higher have 64 megs due to the forseen need for space. What I've been told is that if you're part of the beta program and you have a 16-meg unit, it will be swapped out with a 64-megger. The current plan is also that when 4.0 goes GA, people with 16-meggers will also be able to swap out with 64-meggers. They have the capability to upgrade the RAM so its easy for them to do it. Again, this is the PLAN.
Second, SIP support on SOE. This has nothing to do with VCMs. All existing VCMs will be compatible with SIP on 4.0. It is purely a memory issue. The SOE, 403, and 406v1 all had 16 megs of RAM. Now, they've stripped SIP because that piece of code is huge. In fact, even if they had found a way to squeeze it into the SOE, the next maintenance release would probably push it over the limit, so whats the point. Imagine upgrading to 4.0 and not being able to load a bug fix. Then you'd really be upset.
The 403 & 406v1 have been around for years and the writing was on the wall when the 406v2 took both of their pricepoints. So, it not supporting 4.0 isn't too surprising.
In terms of 64xx support. Again, its not that it won't work, but if there are bugs, the current decision is to not fix them for that set series. This decision was apparently based on feedback received last year when the question was asked. Therefore, if anyone wishes this to not be the case, they need to shoot an e-mail over to "newprodintro" at avaya dot com so they can re-evaluate that decision. If its just one or two people, its not worth the R&D (thats me talking), but if its 100, thats a different story.
Hope this clarifies some things and shines some light where there was darkness.
