[Asterisk-Users] Skill-based routing

Simple solution.  Use different queues for skillsets, add agents with 
penalties based on their skillset.  1 means expert, 100 means you just 
want the call answered if nobody with a lower penalty is available.  Use 
an IVR to direct the caller to the correct queue (topic). 

Penalties can be set through the manager interface with a small patch.  
I did not write the patch and therefore cannot supply it but it is 
possible and took a good developer about ten minutes to write.

Thanks,
Steve
