How to get detailed dial info later in dialplan

This is the dialplan

exten => TWO,n,Dial(SIP/gsm0/075111111&SIP/gsm1/075222222,20,m(sing)M(whoanswered))

now, the question is how to get this extensive dial channel info later in the macro?

I need to get either 075111111 or 075222222, based on who answered

exten => s,1,Set(EXTENSIONZ=${CUT(CHANNEL,-,1)})
exten => s,2,Verbose(${EXTENSIONZ})
exten => s,3,Set(CDR(whoanswered)=${EXTENSIONZ})
exten => s,4,Set(CDR(userfield)=${EXTENSIONZ})
exten => s,5,Verbose(EXTEN=${EXTEN})
exten => s,6,Verbose(DNID=${CALLERID(dnid)})
exten => s,7,Verbose(BRIDGEPEER=${BRIDGEPEER})

I tried all this, but it only gives info about the channel like this: SIP/gsm1-00008dc3 etc…

Please help, any help appreciated!
