But before I step into this topic, I want to talk a little bit further about digital transformation. Digital transformation does not mean anything in regard to technology. Furthermore, it is indicated to change your business approaches. Transform and innovate your business and that should be empowered throughout the entire technology using Microsoft Cloud Services. Even here we have the question, what does this mean? Transforming your business? Well, in the past the IT departments told the businesses what is possible or not. This is going to change entirely.

The IT department becomes the service Department for the entire company the fir...

In Exchange 2007/ 2010/ 2013, you are able to set different security configuration for your SIP Traffic. Therefore special configuration between Gateway, Lync (via Exchange Dial Plans) and Server-to-Server Communication can be defined. Let talk about Exchange 2013 and Lync 2013 UM integration, especially for your configuration in your live environment.   With Exchange Administration Center (EAC) or the Set-UMDialPlan cmdlet in PowerShell you can define your SIP Security configuration. When you configure the UM dial plan to use SIP secured* ( [-VoIPSecurity <SIPSecured | Unsecured | Secured>]) or Secured mode, Client Access and Mailbox servers will encrypt the SIP signaling traffic or the RTP media channels or both. For Lync, you need the special SIP Secured Mode (described below) VoIP security mode, can be configured as: -           SIP secured (SIP Secured setting only protect SIP traffic using TLS while RTP tr...

I just follow up with a discussion I had with a customer who operates a huge Enterprise Network and 30.000 Lync User. We had three distributed Lync Pools around our region and each of this Pool had a consolidated AV Server Setup and seperate Mediation Server. We needed an integration with and behind the CCM 7.x. Estimated for Enterprise Voice, 20% of the user should use Lync as their primary phone.

Hi all, Just some similar for Lync, what we have to do for the Cisco Integration (SIP Trunk) How to configure a SIP trunk between Cisco Call Manager 5.x or 6.x and OCS 2007 R1 or R2 ( it is the SAME for LYNC ) Lync is an IP PBX with its extensions 3xxx and you need to connect it with Cisco PBX with extensions 7xxx . for the SIP trunk to work fine we need to have some specific configuration on that trunk , if any of these settings are not configured right then you will not be able to make a stable calling between Cisco and LYNC. For my customer i could define: LYNC customer uses the internal Extension 3XXX, CISCO accepts E.164 number, e.g. +6031234567898 (+, country code (2), Area code (1-2), number (7)) 711µlaw is used N on-secure SIP trunk (no TLS encryption) http://www.cisco.com/c/en/us/td/docs/voice_ip_comm/cucm/admin/7_1_2/ccmcfg/bccm-712-cm/b06trunk.html You find the config: Device Configuration SIP TRUNK CISCO: ...
