Skype for Business (cloud) and on prem CUCM

[Peter Valdes]

Hi,

I have read alot of discussions on Skype for Business (O365) and on prem CUCM but I haven't seen any documentation on the Cisco configuration side.

We currently have O365 SfB and CUCM / IM CUPS v10 and we want to make call on Skype via CUCM -> Voice GW -> PSTN.

Inbound call should go backwards.

Cloud Connector Edition with your SBC was a solution but I cannot find the integration of SBC and CUCM/CUPS.

Could someone please point me to the right direction. CUCI Lync isn't a solution we want as it will just cause confusion with end users.

Thanks

Peter

Hi Peter,

To connect CUCM/IMP with O365 you need to have S4B on-prem server. O365 will connect to this server which connects using SIP trunk to CUCM. 

If you are using Expressway deployment, then version 8.9 supports integration with O365 without the need for on-prem server.

Thanks Mohammed.

With the O365, we are using E3 license. Do we need any add-ons to this license? Standard E3 license does not have the option to create a SIP trunk or any connection back to expressway-e...

Hi Peter,

Please check page 7 of the following link

The Expressway pair at the edge of the network can now traverse messaging and presence traffic between IM and Presence Service and external organizations using Skype for Business or Office 365.

A CMS based integration with S4B via Expressway is however well documented in the following guide

Hi Manish,

Thanks for the information.

I will propose the expressway/CMS solution but I will need an alternate since it may be too expensive just to integrate Skype with Cisco.

Can you confirm if the Cloud Connector Edition is supported?

I read from Microsoft that its a SIP Trunk connection from CCE to on premis PABX (CUCM), but this will come with limitations which Microsoft CCE is not clear on.

Hi Peter,

I do not see any documentation confirming or denying the support for Cloud Connector edition, it is recommended to verify the same with TAC or your Cisco Account team.

Hi Peter,

I hope you are having a great day!, your question was all about terminating PSTN calls with O365 Sfb and I could see that the solution mentioned below by Mr. Manish is for Video / Instant Messaging scenario. Did you get the solution for your actual question?
