Dear Experts:
We are trying to implement office 365/Lync Online with our Avaya ACE (Agile Communication Environment).  
Avaya said we don't need a dedicate LYNC server on premise.  But our consultant from MS said that we need a LYNC server on premise in order to integrate with voice/telephony.

Does anyone know how it works to integrate ACE and MS LYNC online?

I usually have the same opinion from MS which because we was told that way if you want to keep your lync client untouched.

but looking at

it seems it is a CEBP and able to use HTTPS to overcome it ..

and this document explain how it intergrated with office 365

It seems need to install a Avaya addon to the lync client to overcome this.

it sound good :)

One quick question:
We have E3 plan which includes Lync server Enterprise license.
One thing confuses me:
It said it is required to have both Standard license and Enterprise license in order to use conference as presenters and attendees?  
It also mentioned that LYNC External connector.  what is that for?  I thought all office 365 users should be able to use them anywhere even if they are at home?  What is the external conector license for?

this itself secure a separate question because it has nothing to do with this topic.

Lync External connector is basically a financial decision more than a technical decision.
this licence is designed to support additional user that is not employee of the company but require to use lync, like contractor, external vendor and etc. (don't confuse with external connectivity, you always can communicate with them external)

Office 365 i did not notice any lync external connector licence able to be combine in used.

further, for standard licence and enterprise licence, if for E3, you probably got all the licence required. you don't need to worry unless you want to mix match E3 with E2 and/or E1

I will strongly suggest you to read the office 365 service description which explain most of them.
