Description (partial)

Calling Party Transformation CSS is not applied for endpoints registered via Collab Edge MRA.

This is happening because Expressway will add P-Asserted-Identity (PAI) as VCS always done.

CUCM never expects PAI coming from Endpoints and it rewrites already applied changed 
Calling Party Number by number presented in PAI header.

- endpoint is registered via Collab Edge MRA (Jabber clients, TC-based endpoints- EX/MX/C)
- endpoint have Calling Party Transformation CSS configured
