Could anyone explain to me what is the difference between Call-ID and UniqueID of SIP calls, please? Which one could be used as an ID to trace, for example, the status of a call with Manager API and PHP? Thanks, Alex

The UniqueID is assigned by Asterisk to the call itself and should be used for tracking the call via the Asterisk interfaces.
