Symlink of outgoing to NFS directory not working

I have moved the /var/spool/asterisk/outgoing directory to outgoing-, then done an ln -s to an NFS directory (example ln -s …/…/…/nfs_dir/outgoing outgoing) but now asterisk does not pick up any files from the outgoing directory to dial out.

I can see the files, I have check the permissions and owner, and asterisk does not give any error in the error log.

Anyone know why, or how to fix this?
I think I consider this a bug, but it may be a “feature” :smile:

I am running:
CentOS 5.2
Asterisk 1.4.24
