Title: How old is 3300 R9.0 UR3 Mitel switch software?
Post by: acomber on September 28, 2011, 11:22:47 AM

We are considering upgrading to the new MiTAI SDK v5.  The earliest version of MCD it supports is  3300 R9.0 UR3.  Does anyone know roughly how old this version is?  Are many Mitel sites likely to still be using this version or earlier?

Yes some sites are still using old versions however as releases are increased support goes away for older releases or become costly. A highlight of progression from 9.0 is 9.0 --> MCD 4.0 --> MCD 4.1 --> MCD 4.2 and soon to be MCD 5.0.

9.0 UR3 is approximately a year old and 9 ish releases behind the current. That is a rough give or take.
