The last bit of info I heard late last year was that Avaya were planning on stopping support to release 6.0 when issue 7.6 is released. I also heard that 7.0 and 7.5 might be reviewed as the plan was for all 7.5 customers to be given a free upgrade to 7.6, hence no need to support 7.5 or lower as it seems to have caused so many problems since it's release.
I don't know for sure if this is true, but I was told that Avaya were under a lot of pressure to be certain that the next release of software will have been fully tested before release. I know that the past few releases by Avaya have done some damage to the CS1000 platform in terms of confidence and reliability etc.
Some of my customers have raised the question after e.g. an upgrade from a Option 61 / 81 etc, why they now have service affecting problems on the CS1000e, when their old modular Option 61 / 81 system happily ran year upon year without any faults.
Of course migrating from a TDM based system to a IP based one will involve encountering situations that would have never existed before, but even with this, is does seem that the CS1000e is more work intensive when you have customers that have remote media gateways and this is where I think most of the problems exist.
I also know many customers who have standalone CS1000e sites that don't have any problems.
All the best
