FreePBX + Asterisk with Cisco 8961

We have a couple Cisco 8961's that we are trying to add to our FreePBX Asterisk system. I have searched the internet and have found some "working" configs but cannot seem to get these phones to talk properly. We would need somebody to write the configuration for the phones based on our current setup and/or guide us through any extensions or modules that need to be installed on our system to get these phones to work. Network configuration info would be supplied once somebody is chosen. FreePBX 2.9.0.12 Asterisk 2.9.0.5 PBX End Point Manager 2.10.3.2
