Endpoint Manager-Polycom-IP 430 Provisioning issue

I just setup a new FreePBX server and am using the Endpoint Manager to provision Polycom IP: 430’s, 501’s and 550’s. The 501’s and 550’s seem to work normally as far as grabbing the firmware (slot 1, Polycom 1.07) and being able to call between phones. The 430’s however are not cooperating.

IP 430-Phone 1: Rev. 3.2.2.0019 Aug 24, 2006 (it does see the provisioning server and does grab an IP address)

  1. Waiting for network to initiate
  2. Updating initial configuration
  3. Error application not present

IP 430-Phone 2: Rev. 3.2.2.0019 Aug 24, 2006 (it does see the provisioning server and does grab an IP address)

  1. Waiting for network to initiate
  2. Updating initial configuration
  3. Loading application
  4. Running “polycom/1/sip.ld”
  5. Welcome! Processing configuration (it hangs here)

I have also tried the firmware (slot 2, Polycom 1.01) which is the same bootrom version but one is lync and the other is non-lync.

This is my first FreePBX server and first time setting up a SIP server, so please answer in Layman’s.

Thanks.
