You probably want the Dial event. It is raised both at the beginning of
the Dial, as well as when the Dial completes.

https://wiki.asterisk.org/wiki/display/AST/Asterisk+11+ManagerEvent_Dial

Note that the Channel: field will contain the name initiating the Dial,
the Destination: field will contain the channel name being dialled, and
the Dialstring: field will contain the non-technology specific portion
of the thing being dialled.

For example:

exten => 500,1,Dial(SIP/digium02)

Results in:

Event: Dial
Privilege: call,all
SubEvent: Begin
Channel: SIP/10.x.x.x-00000002
Destination: SIP/digium02-00000003
CallerIDNum: 657-5309
CallerIDName: digium01
ConnectedLineNum: <unknown>
ConnectedLineName: <unknown>
UniqueID: Asterisk-01-1359052866.2
DestUniqueID: Asterisk-01-1359052866.3
Dialstring: digium02
