Implementing Cisco IP Telephony and Video Part 2 (CIPTV2, legacy) — Question 34

Which two devices or applications support call preservation? (Choose two.)

Answer options

• A. JTAPI applications
• B. CTI applications
• C. a software conference bridge
• D. an annunciator
• E. SIP trunks

Correct answer: C, E

Explanation

The correct answers are C and E. A software conference bridge allows calls to be preserved during conferences, and SIP trunks maintain call sessions. JTAPI and CTI applications do not inherently provide call preservation, while an annunciator is used for announcements and does not support call preservation.
