  • [Skype for Business] Skype for Business and Lync 2013 DDC - Detailed Design Calculator

    Une mise a jour d'outil sympathique est disponible sur les gallery technet: Skype for Business and Lync 2013 DDC - Detailed Design Calculator


    DDC is a simple offline, Excel-based, low-level design calculator for Microsoft Skype for Business and Lync 2013 on-premises deployments. Fill in host names, IP addresses etc., and DDC will calculate DNS records, certificate names, firewall rules, deployment scripts and several other design elements to help speed-up your deployment.

    DDC is a continuously evolving project and you should expect frequent updates with new features added over time. It is and will always be free.


    New in version 5.0.0:

    New in version 5.0.0:


    • Support for multiple SIP domains (up to 8), each with several configurable options (strict domain matching, SIP/XMPP federation, etc.)
    • DNS tables reorganised for multiple domain support (records are sorted by domain).
    • Added the ability to include/exclude external servers (Edge pool, Reverse Proxy) from the deployment
    • Added the ability to choose AD or main SIP domain name for Pools and Web Services names (earlier DDC versions used primary SIP domain name by default and did not allow to change)
    • Option to deploy 1 or 2 network cards on dedicated Mediation servers (separated internal and PSTN IP addresses). We have not included such option for collocated Mediation (not recommended)
    • Option to use separate public IP addresses for external web-based applications (FE and Director pool web services, Office Web Apps)
    • Support for Office Web Apps farms (up to 6 nodes)
    • Additional scripts (setup accounts for synthetic transactions)
    • Required empty input cells displayed in red


    • Supports Standard and Enterprise pools (up to 12 nodes), with pure device-based load balancing (HLB) or a combination of DNS load balancing and device-based load balancing for web services (DNS LB);  
    • Supports Edge, Director and Mediation pools (up to 12 nodes per role) with HLB or DNS LB;  
    • Supports up to 4 PSTN gateways (can be media gateways, direct SIP trunks, etc.) with or without media bypass and configurable SIP over TCP or TLS, media ports, media bypass  
    • Ability to specify custom media ports for clients and servers. DDC automatically applies consecutive non-overlapping ranges, and creates the appropriate commands on the Scripts sheet to apply these on to your deployment;  
    • Calculates internal and external certificates CN and SAN; for the external certificate, it provides the option of separate or single certificate for Edge and Reverse proxy;
    • Calculates DNS entries for internal and external zones. Further to that, DDC generates a script (in the Scripts sheet) which will automatically add the required records for both pinpoint or split-brain DNS.

      Calculates firewall rules for: 

    • Internal firewalls (internal-facing DMZ); 
    • External firewalls (external-facing DMZ);
    • PSTN: The PSTN firewall sheet calculates custom rules for firewalls behind PSTN gateways, if any;
    • Endpoints: the internal client Firewall sheet calculates custom rules for personal firewalls installed on clients, and rules required in scenarios with endpoints segregated by VLANs or other restrictions in place.

      Script section: new in version 4.x and still at an initial stage, but with plans to grow it over time. Currently it supports:

    • DHCP: We have included a modified version of DhcpConfigScript.bat (http://technet.microsoft.com/en-us/library/gg412988(v=ocs.14).aspx), with the correct hexadecimal values automatically calculated and included, based on your design inputs; this removes the requirement to use dhcputil to generate the script and makes it ready to run on x86 and x64 Windows DHCP servers;
    • DNS: Scripts to create necessary records based on dnscmd (with both pinpoint and split-brain, based on your selection);
    • Office Web Apps: scripts to automate certificate request (through certutil), installation and web farm creation;
    • Forward Proxy exceptions;
    • QoS: PowerShell commands to configure custom port ranges;
    • Setup accounts for synthetic transactions.
