Users are unable to save configurations to an IP500v2/Server Edition due to the following false error:
No more than 300 Hunt Groups are allowed in Non-Select IP Office Solution
This is caused by a bug in Manager which which causes hunt groups on multi-site systems to be multiplied by the number of sites e.g. if a solution has 80 hunt groups over 4 sites, this will falsely think it has 320 groups configured.
A custom build of Manager can be obtained from Avaya technical support as a general release fix has not yet been implemented. This will however be resolved in R9.1 SP3. If you do need a custom build, the ones you need to request are as follows:
R22.214.171.124 Build 2
R126.96.36.199 Build 1
