jdobnerjr,
Well, if you don't mind I will try to answer some of this for you now. I am not sure when you last worked on one of these though.
1. G.722/Wideband audio...: Look under IP Configurations there is a wideband codec called BroadVoice 32 in later versions.
2. Better ability to manage conference calls from 5360 IP Phones (it is a wreck of a phone when making a conference call): Not sure what you mean here as it works the same as all the other 53xx series phones. To be honest it has worked the same way on all phones since the Axxess days.
3. more than 12 characters for usernames displayed on phone: I haven't had too many issues with that limitation to date, but how many would you want to have; 16?
4. ability to show direct-dial number on screen if desired: There is a feature called [Outside Party Call Information has Priority] are you request a feature code to be able to change that on the fly?
5. getting rid of the "OUTGOING" button and standardizing the system like every other system by utilizing "9" as the external line digit: This has been available since the Axxess days as 8 is just a feature code and you can change it to whatever you want it to be; just like ARS is a feature code. Inter-Tel standardized on dial 8 to reduce misdialing 911 which by the way is also a feature code.
6. more intuitive voicemail - ability to transfer to VM by using the envelope key and then the extension of the user: The ability to program the buttons as you want has been around since the Axxess day and didn't change with the 53xx series phones; you can make that a DSS/BLF of Voice Mail if you want.
7. changing the redial/conference key to actually work as a conference button - rather than just a redial button: I am not sure which phone type you are referring to here but it doesn't matter as the features for Redial, Conference, and Transfer are separate in the Axxess on thru to the MiVO-250. There is a Transfer/Conference key on the 3300 is that what you are referring to?
8. the "X" button does nothing - make that work: The X button on the MiVO-250 is preprogrammed to be the Special Key [SPCL], but you can make it whatever you want it to be just like all of the other keys on the phone; except the dial pad keys that is.
I could go on and on, but Mitel could spend some time and energy putting time into this system and blend it together with the smaller ShoreTel systems for greater sales.
I am going to out on a limb here and say that you are most likely a ShoreTel technician that is struggling with this product since it isn't like the other Mitel designed systems; or the ShoreTel systems since they are similar to the Mitel systems.
I am not saying that the MiVO-250 is the greatest system out there, as I don't believe there is one, but I do think it does well for the niche it is designed to work in. They have also started coming out with a few new features in 6.3 that are similar to the 3300; i.e. Direct Page.
Thanks,
TE
