I've got 80 users all using SfB Online. Knowing that I have to get Teams up and running before the axe falls on SfB Online, I pre-ordered a CCX 500 to see what the voice side of Teams is like. Yesterday I unplugged my trusty VVX 500, converted my account type from Islands to Teams-Only, and switched to my new phone.
The phone booted up to Teams, but then would not let me sign in. I poked in the settings and found that had not picked up the proper VLAN assignment. I guess that CCX phones will need a different or additional setting in DHCP than VVX did.
After setting the VLAN, I was able to sign into Teams. I was also obliged to enroll the phone in InTune because it's an Android device. I subsequently found this blog post and will make the necessary adjustment to my MDM policies so I don't have to do that for every new phone.
I was able to receive calls from both inside and outside my company. I was also able to continue using my Logitech wireless headset that I had previously used with my VVX phone. When it came to placing calls, though, I made the following discoveries:
I'm curious to learn about other people's experiences, and hear any advice you might have.
Hi JoeNaxion, thanks for sharing your experience. I've requested a CCX 500 demo unit from our vendor, so this information will be helpful.
Just to make sure you're aware, while SfBO will be retired on July 31, 2021, support for 3PIP phones (like the VVX 500) will continue until July 31, 2023 (per this post on the Microsoft Teams Blog). That being said, there are some major functional limitations. For example, I discovered that when you attempt to turn on Call Forwarding from a 3PIP phone when the user is in Teams Only mode, it appears to succeed but calls aren't actually forwarded. Call Forwarding can only be configured through the Teams client.
Like you, I'm not seeing the Voice > Dial Plan option on the Teams Admin Center. I had a look on the Microsoft 365 Roadmap page and it looks like Dial Plans for Teams is part of a Microsoft Teams - Phone System Administration Enhancements feature that is rolling out this month.
I notice that, unlike the windows client, the call tab on the CCX does not display favorites or speeddials, (and their status). Likewise It does not seem to display an assistant's 'covered' lines as favorites as is done on the VVX with SfB.
