Skype OnLine - CCE Connector on Dynamic Ip Address RRS feed

  • General discussion

  • Dear All,

    I had come across a unique situation , where we needed to install Skype-CCE Connector behind a Dynamic IP Address, 

    Below are the steps followed,

    1) Use any free or paid service to create a Dynamic DNS Record , in my case I was using a Fortinet Firewall which allowed a very fast and reliable dyndns services

    Dynamic DNS Registration

    2) Create a Cname record in public DNS that would point towards 

    3) Certificate with below names,

    The main certificate is : accesssfb.<domain name> pointing using CName to DYNDNS name,

    and the other is sip.<domain name>

    Now follow the steps and install the CCE , at the time of writing this blog it is CCE2.0

    How the CCE Edge is accessed from SFB Online for making PSTN Calls via PSTN gateway,

    SFB Client àOffice 365 Cloud àConnects to Accesssfb.crayononline.com (Which is pointing to WAN Interface of the firewall @ TCP/443 àNAT// CCE-Edge Server,

    Now connect to hyper V machine,

    Basically this task need to be done 3 Servers 

    1) CMS Server

    2) Mediation Server

    3) Edge Server

    Export the local configuration file , Since CCE is not using any sql Backend , All configurations are stored local the each of these servers,

    Export the Configuration

    A Zip File would be Created , kindly do not extract this file, just open the file and extract the file DocItemSet.xml

    Open File  look for NetInterfaceSide="External" InterfaceNumber="1" IpAddress="<Private IP>" ConfiguredIPAddress="<External ip Address>"

    The field for Configured IP ADDRESS must be changed to reflect the new IP Address,

    basically just replace the old value with new) and save the file,

    Now Import this file to the config.zip file ( it would ask for replacement of old file , confirm this with “yes”)

    Import the configuration

    Open Skype Power Shell and Import the update Configuration file 

    From Save PowerShell Windows do a restart of Services,



    The same action need to be done on skype servers ie., CMS Server , Mediation and Edge Server,

  • Hi Hasan,

    for point 2.

    "2) Create a Cname record in public DNS that would point towards "

    Towards what?

    So meaning my WAN interface and CCE Edge will be having the same IP?
