CER 1.3(2), CCM 4.1(3)sr4b, 7941 phone.
I'm configuring the route patterns for CER, and found the "Calling Party Modification" option which supposedly lets you use a generic route pattern rather than having to have a separate route pattern for each ELIN. This would be of great benefit to us, as we have approximately 36 ELINS and may be adding more.
However, when I enable this option and also check "Enable Calling Party Number Modification" for the CER user, I get fast busy and the call never makes it out. Alerts from CER still work though.
I can't find any further documentation as to if/how the route patterns and CTI route points need to be modified for this to work. Has anyone out there done it?
