In a SIP trace capturing PPM messages, which device sends the getCallHistory PPM request, and what is it requesting?

Question

Options

• Athe SIP endpoint; It is requesting its call log to be retrieved from Session Manager.
• Bthe SIP endpoint; It is requesting its contact list to be retrieved from Session Manager.
• Cthe Avaya Aura® Session Manager (SM) server; It is requesting the call history from System
• DSystem Manager; It is requesting the call log history from Communication Manager.

• A
  88% (45)
• B
  2% (1)
• C
  6% (3)
• D
  4% (2)

Explanation

Option A is correct because in Avaya Aura PPM (Personal Profile Manager), the SIP endpoint acts as the client that initiates the getCallHistory request to Session Manager, asking SM to retrieve the endpoint's stored call log - this is how the phone repopulates its call history after registration or a restart.

Why the distractors fail:

• B is wrong because getCallHistory specifically targets the call log, not the contact list; retrieving contacts would involve a different PPM request (e.g., getContactList).
• C is wrong on two counts: Session Manager is the server that responds to PPM requests, not the initiator, and "System" is an incomplete/vague reference.
• D is wrong because System Manager is an administrative platform, not a SIP signaling device, and Communication Manager does not store PPM call history - Session Manager does.

Memory tip: Think of PPM like cloud sync for a smartphone - the phone (endpoint) always reaches out to retrieve its saved data. The endpoint gets history from SM, not the other way around. If the question says "getCallanything," the requester is always the endpoint.
