Follow me - no audio

PBX Firmware: 5.211.65-6
PBX Service Pack:

I have set up the Follow Me option like this;
Initial Ring Time: 10
Ring Strategy: ringallv2
Ring Time: 20
Follow Me List:
Announcement: none
Play Music on Hold: ring

Confirm Call:
Remote Announce: default
Too-Late Announce: default

Mode: default

Follow Me: normal extension behavior

The call comes in, then forwards as expected to the cell phone. However, when I answer the call, there is no audio either way.

Any thoughts/help will be greatly appreciated.
