What are RealeaseSource in show call history voice

[HARIS_HUSSAIN]

I am trying to figure out from the show call history voice command what does ReleaseSource=1,2,3,4,7 etc means.

Basically i an trying to figure out which party has disconnected the call.

#show call history voice
Telephony call-legs: 7
SIP call-legs: 35
H323 call-legs: 0
Call agent controlled call-legs: 0
Total call-legs: 42

GENERIC:
SetupTime=688819930 ms (10:00:43.017 QAT Thu Feb 7 2019)
Index=13347
PeerAddress=6950
PeerSubAddress=
PeerId=40020
PeerIfIndex=74
LogicalIfIndex=0
DisconnectCause=10
DisconnectText=normal call clearing (16)
ConnectTime=688824880 ms (10:00:47.967 QAT Thu Feb 7 2019)
DisconnectTime=688834930 ms (10:00:58.017 QAT Thu Feb 7 2019)
CallDuration=00:00:10 sec
CallOrigin=1
ReleaseSource=4

Each party of the call is given a number and the release source is the
number of the party released the call. This can be a phone, voice gateway,
etc.

So What does ReleaseSource=4 or ReleaseSource=3 Means.
Is there any document where these are defined.
