Is the feature of SIP Fork related to missed calls?

The feature of SIP Fork is not related to missed calls. SIP Forking refers to the ability of a SIP server to send a single invite request to multiple endpoints simultaneously. This is primarily used in scenarios where a call is intended for multiple users, such as ringing multiple phones or devices at once.

When a SIP fork occurs, the server can route the call to multiple devices, enabling functionalities like hunting or simultaneous ringing. However, missed calls are not a direct function of SIP forking. Missed calls generally occur when a call is not answered or rejected, which is a different process altogether involving call handling and termination.

By understanding SIP Forking's focus on call distribution rather than handling missed calls, it's clear why the correct answer is that it is not related. The other options imply specific contexts or situations where SIP Forking might apply, but they do not accurately address the core functionality of this SIP feature.
