I have installed multiple 32 bit and 64 bit versions including latest 64 bit: FreePBX-Distro-Net-64bit-1.1002.210.57.
Whenever I am running the 64-bit distro, voice mail prompts are choppy and have clicks or pops in them sometimes skipping sub-second parts of the audio. Was thinking it was related to Polycom firmware updates, etc. Went back to 32-bit and problem was gone. Re-installed 64-bit and problem is back.
Running PBX Service Pack: 1.1002.210.57-1 on:
Processor: AMD A6-3600 2.1Ghz processor
Memory: 6GB of RAM
