We use ICD to handle a complex queuing situation. This involved a new
distribution algorithm and hooks to the Asterisk management interface.

ICD suffers quite a bit from over engineering. The complexity comes mainly
from the same analysis that makes Asterisk overly comples - signalling is
handled in parallell thread. There are some locking issues and races we
have not been able to track down. For our use we no longer see any hangs,
but from time to time agents enter an inconsistent state.

Both Asterisk and the ICD subsystem would have been easier to implement 
and debug had they chosen a single-threaded model for the control flow and 
left the threads to handle the payload (voice etc).

ICD has its own mailinglist at Icd-user at lists.sourceforge.net. There is 
close to zero traffic there as well. I think the authors read it though.
