[Asterisk-Users] Sip transfer and redirect in a Company setting

[C F]

If I understand your problem correctly, you have user a setup with vm
box a, and user b with vm box b, when secretary uses local callFWD
from phone a to phone b, vm of b picks up. And you want that if it was
redirected from phone a vm box of a should answer. I think (I never
tested this) that the RDNIS variable (${RDNIS}) will hold the CallerID
of phone a, which you can use in your dialplan to use for voicemail if
it exists, something like this will do:
exten => _1XX,1,Dial(SIP/${EXTEN},45,tr)
exten => _1XX,2,GotoIf($[${RDNIS} > 0 ]?10)
exten => _1XX,3,VoiceMail(u${EXTEN})
exten => _1XX,10,VoiceMail(u${RDNIS})

I'm not sure if DNID or RDNIS will work for SIP phones, but one of
those should work.
Another way to get this done (ugly), is to set a variable for the
channel before you use the Dial command, like this

exten => _1XX,1,SetVar(ORIGINAL_EXTEN=${EXTEN})
and then test if ${ORIGINAL_EXTEN} is different than ${EXTEN}

I hope this helps.
