Skype For Business Cloud Connector Edition version 2.0

Microsoft released Skype for business Cloud Connector Edition in April, 2016 for GA. As we know Cloud Connector Edition makes it possible to connect any existing telephone circuit to Cloud PBX in Office 365 using the simple server and minimal configuration. The availability of Skype for Business Cloud Connector Edition comes with additional capability of on-premises PSTN connectivity for existing Lync Server/Skype for Business server deployment. That allows the user’s phone capability to be managed out of Office 365 while their phone call continue to use their existing phone number, circuits and PSTN provider contract.

Skype for Business Cloud Connector Edition Version 2.0


Now Microsoft released Skype for Business Cloud Connector Edition version 2.0, there are multiple improvement are:

Media Bypass
Media bypass allows a client to send media directly to the PSTN next hop a gateway /SBC and removed the CCE from the media path, which will improve the voice quality, minimum latency, possibility of packet loss and other failure. It will improve the scalability and enables a higher number of concurrent calls. Also it will reduce the load on Cloud Connector.





Support of 16 Cloud Connector Edition per one PSTN Site:

Initial released of Cloud Connector Edition support only 4 instances of CCE are supported per PSTN site, means each Cloud Connector can support up to 500 simultaneous calls, it means one site can support 1500 simultaneous call/lines (1 instance reserved for HA). The ratio of 1:10 means we had support for 9000 to 15000 of available line to users.
Now many organization want to centralize Cloud Connectors in one location for cost save and the number of the users can exceed 15000 and need more Cloud Connector instances per site. In new released Cloud Connector Edition version 2.0 can support 45,000 to 75,000 simultaneous call/lines.


Ability to manipulate SIP headers for billing or interoperability purposes:
Cloud Connector Edition version 2.0 enable manipulate of SIP header via the INI file. We can manipulate following headers from INI file:
Enable Fast Fail-over Timer- Default value is “TRUE” if outbound calls, if you not answered by the gateway within 10 seconds, call will routed to the next available gateway, if the no addition trunks than call will dropped, in this case slow networks and gateway response when the call take more than 10 seconds. Now we need to change the value to “FALSE” same time we have to change the value from connected SBC or Gateway also.
Forward Call History: These parameter turn on SIP headers that are used to report the initial caller in simultaneous ringing, Call forwarding and Call Transfer scenario, setting the parameters to true will turn on two SIP headers History-Info & Referred-By.

Forward PAI: PAI is a private extension to SIP which enables SIP servers to assert the identity of authenticated users.


Use of Office 365 Skype for Business account instead of a Global Administrator account
Now any account of with Skype for Business administrator role to perform management task, this will help larger organization with many administrator to easily management to keep secure access rights.

Auto-generated passwords for local administrator of Cloud Connector instances:
No longer required the manually create a password for the forest administrators. Password for those accounts are generated during the installation. In initial released of CCE during the deployment, there were two account created at the forest level and one account for each Domain Account (VM).

Hybrid Voice flag in Mediation Service User Agent to better distinguish Cloud Connector calls in the Call Quality Dashboard means when a call is placed every server or client reports its name in SIP user-Agent header for diagnostics purposes.

Improvements to self-monitoring and self-troubleshooting process:
One of the critical improvement is self-monitoring and troubleshooting mechanism. New release added following events, if one of the events outlined above is detected, the entire instance of the Cloud Connector is drained and marked as offline:
·       One or more Virtual Machines of a Cloud Connector instance are not connected to internal or internet virtual switch.
