I am currently using Inter-Tel Axxess v. 9.002 and really would like to get some form of unified communications back. We had it about 7 years ago, but Inter-Tel dropped support beyond Office 2000.

I am back looking at it and have been proposed to upgrade to the Inter-Tel (Mitel) CS5000. We are not using VoIP and have no immediate need or it, but I know that is the future. We have no issues with the Axxess system and I am not a fan of upgrading just to upgrade, but the UM features of the CS5000 sound appealing.

Does anyone have experience with both systems? What are the pros and cons of migrating to the CS5000 over the Axxess? What about the support of cell phones (Blackberry, Android or WinMo) on the CS5000? I was told you could integrate various handsets to the system.

Thanks for any info you might have. Just trying to make an educated guess as to which way to go.
