Lync 2013 Complete Lab Guide Using Single Public IP Address – Part 3 – Building the PBX

In Part 2 we built the raw components for a Lync deployment. Before we create Lync we first need a PBX system if we are going to use enterprise voice. The PBX chosen for this lab is Elastix 2.5 which is an open source pbx system available for download here: http://www.elastix.org/index.php/en/downloads.html

In order to process calls to and from the PSTN we will also need a hosted SIP account with an online SIP provider. For this lab I have chose to use SIPGATE as the sip provider, http://www.sipgate.co.uk

Please sign up for your own account with them. It is free to sign up and use the service for inbound calls. You can also make calls to freephone numbers without charge, so is perfect for testing a simple EV deployment with Lync.

This part assumes that Elastix has been installed to PBX01, configured with the IP address and you have your Sipgate account information.


  1. I know this is old article but where you able to finish this tutorial. This is the only one that I have found that actually explained how to setup Lync from top to bottom. Would love to know if you have any rough draft of the last parts of this great tutorial. Thanks!

    • Hi

      No I never did get this finished, the reason why was I broke my elastix box and lost the configuration I did (which took me hours to figure out). But my friend over at http://www.ohsaycanuc.com aka Jason Wynn figured it out and blogged that bit over on his channel. I realise that I have missed out the voice configuration on the Lync side, however, if you read posts from here: https://skype4b.uk/?s=normalization+rules in partcular the sonus guides this should give your enough information to fill in the gaps.


      • Thanks for the reply back, Mark! That’s too bad that your Elastix box broke. Thanks for the links. Will definitely take a look at those.
