[Asterisk-Users] Sipura 3000 FXO with Asterisk

[Tony Davidson]

I think I can answer for Ed; the calling party does know you've answered as
the ring changes (certainly in my case).  More importantly, I use this at
home and I don't want people getting charged with a call charge for an
unanswered call.  Of course once it goes to voicemail that's another matter
but it's already rung for 20-25 seconds.
