[Asterisk-Users] Able to tell if phone is registered?

[Richard J. Sears]

One method that I use is to dial all of my extensions at once (Office,
home, laptop) and then dial my cellphone. Failing any of those to answer,
it drops back into my voicemail.

exten => ${RJSWORK},1,Macro(stdexten_cell,SIP/${RJSWORK}&SIP/${RJSDESK}&SIP/${RJSLAPTOP}&SIP/${RJSHOME},${RJSCELL})

[macro-stdexten_cell]
exten => s,1,Dial(${ARG1},10,rtm)
exten => s,2,Goto(s-${DIALSTATUS},1)
exten => s-NOANSWER,1,Dial(IAX2/blahblah at NuFone/${ARG2},10,rtm)
exten => s-NOANSWER,2,Voicemail(u${MACRO_EXTEN})
;exten => s-NOANSWER,3,Goto(default,s,1)
exten => s-BUSY,1,Voicemail(b${MACRO_EXTEN})
;exten => s-BUSY,2,Goto(default,s,1)
exten => s-.,1,Goto(s-NOANSWER,1)
exten => a,1,VoicemailMain(${MACRO_EXTEN})
