[Sigia-l] Recommendations for firm specialized in customer support solutions

[Livia Labate]

Hi all,

I was wondering if you have a strong recommendation for a company with 
experience designing solutions for customer support, specifically 
related to call-trees (design of voice-menus navigation systems, 
familiarity with this technology, mapping it to the business processes 
behind customer support, etc).

Thanks,

Livia
