Hi Iñaki,

This might be off topic, but by any chance, do you know a way to make Cisco 
Call Manager Express use information form the 'To' header to route the 
calls..
And as a side none, in order to use 'P-Called-Party-ID' in CCME we have to 
have Cisco Unified Border Element license.

Thank you.

Elnour
