Hi,

thanks for your time!

I definitely have a lot to learn yet.

What I pretend is that asterisk detects that it's not under control and gets 
out of the way. The same way it detects a remote hangup and stops the 
dialplan, it could detect that someone else answered (the line is not ringing 
anymore) and discard it the same way it does when the remote part hangup.

I've read comments in forums and tutorials that seem to imply that this 
happens, but I couldn't find any confirmation (and indeed, it's not happening to 
me).

If you confirm me that this is the normal behavior, then I at least I know my 
solution is in the dialplan and not a card/line/driver problem.

Yes, it's a really simple task, but this should be just a starting point. The 
plan is to start migrating services to the PBX little by little, and the 
voicemail looked like the easier thing to start. I wanted to maintain the 
current analog phones until I feel confident with the asterisk configuration. 
Maybe it wasn't such a great idea, and I should start by moving the phones to 
FXS ports in the PBX.
