It's for UCCX7
The method in my mind is to make use of xml file.
The objective is to create 1230.xml, calling number which matches the data inside the xml file will be directly transfer to ext 1230 queue. There will be multiple xml file for multiple extension number.
It seems the solution in my mind is not very scalable as it will be checking through multiple xml file before making routing decision.
Is there any other better method out there?
