Which protocol is commonly used in conjunction with SIP to handle the actual transmission of voice and video media?

Correct! Wrong!

RTP (Real-time Transport Protocol) is used to transmit real-time audio and video data in SIP-based communications. While SIP handles signaling and session setup, RTP carries the actual media streams.

Which technique is commonly used to enable SIP communication through Network Address Translation (NAT)?

Correct! Wrong!

SIP ALG (Application Layer Gateway) is a technique used to help SIP traffic traverse NAT by modifying SIP packets to ensure they are correctly routed through the NAT device.

How does SIP interoperability with H.323 typically get managed?

Correct! Wrong!

SIP and H.323 are different signaling protocols, and interoperability is managed using a protocol gateway that translates between them, allowing communication between endpoints using different protocols.

Which SIP extension allows for the integration of presence information, showing the availability status of users?
