This is the way we do it, we have it call the local extension as well as a
mobile number, and then you choose where to pick up:

[applications]

exten => _*22*.,1,Answer()
exten => _*22*.,2,DBput(DUAL/${CALLERIDNUM}=${EXTEN:4})
exten => _*22*.,3,PlayBack(call-fwd-parallel)
exten => _*22*.,4,PlayBack(activated)
exten => _*22*.,5,Hangup

exten => **22,1,Answer()
exten => **22,2,DBdel(DUAL/${CALLERIDNUM})
exten => **22,3,PlayBack(call-fwd-parallel)
exten => **22,4,PlayBack(de-activated)
exten => **22,5,Hangup

[macro-dial]
exten => s,1,DBget(DUAL=DUAL/${ARG2})
exten => s,2,Dial(${ARG1}&${OUTGOING}/${DUAL},20,wW)
exten => s,3, VoiceMail(su${ARG2})
exten => s,102,Dial(${ARG1},20,Ww)
exten => s,103,VoiceMail(su${ARG2})
exten => s,203,VoiceMail(sb${ARG2})
