A customer reports that several Remote Worker new hires were trying to call co-workers in the office, but noticed their feature buttons were not working. After running a SIP trace, the administrator did not see any PPM Responses coming from Avaya Aura Communication Manager (CM).
After looking ah how the call flow is supposed to go, the administrator looked at the SIP communication profile and saw that CM had not been administered as a sequenced application.
If CM had been added to the endpoint's SIP Communication Profile as a Sequenced Application, which step was missing in the call flow?

B. PPM is downloaded to Avaya Aura® Session Manager (SM) from CM.
C. PPM is downloaded to the Remote Worker telephone from Avaya Aura® System Manager (SMGR).
D. PPM is downloaded to the Remote Worker telephone from CM.
