I implemented this like so in my default context:
exten => _*21.,1,Answer()
same => n,GotoIf($["${CALLERID(num)}"="<redacted>"]?divert:void)
same => n(divert),Set(DB(divert/${CALLERID(num):-4})=${EXTEN:3})
same => n,Gosub(divertactive,1)
same => n,Hangup()
same => n(void),Gosub(divertvoid,1)
exten => _#21,1,Answer()
same => n,GotoIf($["${CALLERID(num)}"="<redacted>"]?divert:void)
same => n(divert),Verbose(0,${DB_DELETE(divert/${CALLERID(num):-4})})
same => n,Gosub(divertoff,1)
same => n,Hangup()
same => n(void),Gosub(divertvoid,1)
(note: use whatever you need in the GotoIf to validate that the phone
the call is from is permitted to set up call forwarding - unless you're
allowing it for all that can reach the context)
The divert{off,active,void} subroutines are where I handle the
announcements - but you could probably easily implement your own.
At the top of my [voicemail] context, I do this:
exten=>s,1,GotoIf(${DB_EXISTS(divert/${ARG3})}?outbound-standard,${DB_RESULT},1)
(ARG3 contains the last four digits of the number the call came to in
my case, and a success passes the call via the "outbound-standard"
context which is in my dialplan. Your exact requirements may vary but
this may help.)
