Re: How to understand partitions and calling search spaces

Hi,

Simply put, PT is where you are and CSS is where you are allowed to go. For a DN to be able to call another DN it must have permission to call it and it is CSS that gives it that permission.

EG..DN 3002 with PT_int and CSS_int wants to call DN 5002 with Pt_Long and CSS_long.

The CSS on the DN 3002 which is CSS_int must have the partion of DN 5002 which is PT_long.

Hence the CSS on 3002 must look like this.

CSS_int

PT_Long

PT_int.

So essentially CSS controlles where you can go.

This is a very fundamental aspect of CCM. It affects evrything from IP phones to gateways to CTI ports used for UCCX etc.
