Currently we have an on-premise Lync Server and clients with Enterprise plus licenses.
We want to move part of the users to Office 365.
a couple of questions just to make sure:
Are there other things to take into consideration?
Based on the description, it's a sales-related case. For the question you mentioned, I'd like you can directly call our sales and billing team via g.microsoftonline.com/.../280

Hi Snijdor-- hope all is well...
To add to the above resonse -- here's a summary of options for using Lync Voice as a PBX replacement with Office 365. For your question above - please see #2 below. I.e., E4 provides the Lync "plus" / voice CALs - no actual functionality differences vs. E3.
1. First - while MSFT has "some" voice services coming in the near-term roadmap, the features/functionaliy are not comparable to a full implementation Lync Voice and the Office 365 offering is not positioned as a PBX replacement as the full Lync 2010 product is.
Now - on to more description of how Lync voice with Office 365 works. All Lync services move out of O365's datacenters into yours (if on-premise) or partner datacenter (if using hosted) -- i.e., no splitting of Lync workloads &/or sharing of SIP domains. If you have a use case for some users on Lync online & some on Lync voice -- you'll need two SIP domains & use federation to provide the "in-org" collaboration experience. And, existing phone numbers can be ported to the new Lync voice system &/or use a combination of new/existing numbers.
2. Pricing -- the E4 subscription provides the required Lync voice licensing. The Lync Voice licensing components of E4 are comparable to the traditional Lync Std, Ent & Plus CALs. Further -- E3 is comparable to Lync Std & Ent CALs. For customers that may already have Lync Std, Ent & Plus CALs (w/Software Assurance) -- you have additional flexibilty in terms of credit into the O365 plans &/or using "license mobility" benefits to host in partner datacenters.
With a partner hosted approach you will also have hosting fees and SIP Trunking/PSTN access/call usage fees in the $20-40 range per user/mo -- typically this is also going to provide all maintenance/support -- pricing can be in the $20s if using pay as you go minutes or more in the $30-$40 range if using unlimited call packages. If using on-premise -- hw pricing varies depending on architecture, balance of physical/virtual, use of servers or appliances. Add another variable with consulting services -- depending on how much you can handle yourself vs. outsource. And -- you'll still need SIP trunking/PSTN access -- depending on call usage/incoming calls -- you're likely in the $10-15/user/mo or much higher depending on call usage (pricing varies depending on rate for SIP Trunks & per minute outbound calls). Note -- we typically find the ROI / TCO tilts toward hosted models as its challenging for many IT shops to replicate the ops/cost model of a hosting provider.
3. Pricing #2 -- Lync Phones/devices run in the mid 200s for top of the line IP phones, low hundreds for usb phones, >50 for headsets. Lots of options/variance here.
4. Exchange integration --- In MSFT's UC solution -- Lync is im/presence, conferencing & voice, Exchange is voicemail. In an E4 scenario --- Exchange stays on O365 & you can leverage Exchange Online's Unified Messaging service for voicemail (& autoattendant) services. The integration model is the same/similar whether Lync voice is on-premise or partner hosted (I say "similar" if the hosted Lync voice is mulit-tenant vs. private cloud).
5. Sign on -- if you use the O365 ADFS/SSO service -- you can tie in Lync sign on to this. If you use O365's sign-on, Lync users can have the same sign on, but will have a separately managed password. That being said -- there are many options here to provide an SSO experience.
Feel free to drop me a line and I can help answer more questions and help you with options.
