Seems like a good time to try convincing the boss we should move our emails to O365. I know he'll say no, but this is ammo for sure.
I don't think that email only justify cost of O365.
I have excellent mail experience with different web hosting providers that provide email service included for a fraction of price of O365.
For example, Hetzner offers 300GB space with unlimited mail accounts for 17 EUR / cca. 20 USD a month.
(I have not used Hetzner's mail services but I have very good experinece with them in cloud/bare metal services)
I mean - you would not convince me to buy O365 with this argument 🙂
Agreed. We already have O365, but I've been instructed to keep Exchange On-Prem exclusively. Sorry that wasn't implied more clearly.
Correct - you should be using PJsip. Also as far as changing extensions, you can run into the same issue even if you use the same extension number but you change the channel driver from SIP to PJSIP. This is how I've accomplished the task for remote phones that you can't touch. From your EPM, issue a reboot. Then real quick, you change the extension to use PJSIP, go to EPM, and then do a rebuild. If you do it properly, the phone will then grab the new settings and reconfigure itself and work just fine. You can of course do the same thing if you are changing the extension number on it.
