Configure an Audiocodes Mediant 1000 SBC for Skype for Business

We have a Skype for Business 2015 installation to which I want to add Enterprise Voice functionality. We have a Audiocodes Mediant 1000B SBC that needs to be configured to accept the TLS over TCP from Skype and connect to our SIP trunking provider which uses UDP trunks. We also have a legacy FreePBX-based PBX that we need to integrate with Skype while we transition. So the SBC needs to be configured to route 4 digit extensions to the FreePBX box. It also needs to be configured to translate 4 digit extensions from the FreePBX box into skype sip addresses. I will provide you with a diagram of the skype for business deployment, IP settings for the skype mediation servers, the SIP trunk settings, etc. I will also provide you with a remote login to a machine on our network. Due to the sensitive nature of some of our business systems, you will need to do the configuration while monitored remotely. I can be on the phone or instant message during configuration to answer any questions you might have. I'd like to get the project done as soon as possible, but I do not have any fixed deadlines.
