In order to use Enterprise Voice with Office 365 Plan E4 an on-site Lync Server has to be created with SIP link for enterprise voice, this is what i am lead to believe?

Does anyone have any tips about setting this up and/or any providers of the SIP trunk?

The biggest question is what happens when/if the on-premise broadband link is unavailable, does this prevent calls being made / received?

I am looking for a provider that can provide a SIP connection for 70 users from one site via an existing microwave broadband connection 80mb/80mb - does anyone know if this is possible and if so any good providers?

I would like to stay with Lync due to the integration with the rest of Office 365 that is already being paid for ???
 
Thanks for all your replies.

I know there is a big saving in terms of line rental costs replacing an ISDN30 connection (15 channels) with SIP channels, but does anyone have any rough idea how much cheaper it makes the actual calls. I need to be sure that the investment in equipment is worthwhile.

Does anyone have any recommendations on brands of handset/equipment, we would like remote users to be able to receive calls via their laptop when connected to WiFi are there handsets that would do this i.e. USB telephones or, would it rely on Bluetooth headsets like plantronics etc?
 
I wasn't aware you required on premise exchange for Lync Enterprise Voice?

We have already migrated away from on premise exchange to O365 plan E3, which we planned to upgrade to E4 to cover the user cals for Lync servers.

We plan on replacing the entire phone system with new hardware, Avaya system which is quite old approx. 80 handsets, want to cut out current supplier.

We will be getting external support with all this but just need to understand if Lync is the best way forward, having gone O365 it makes sense to have the integration especially with wanting to roll out more remote working for staff.

This is a complete new system we are looking at so all options are open if anyone has any thoughts? Budget is relatively open as it will probably go on a lease once completed.
