Yes, you are using POTS, and there is no way for asterisk (or any
other pbx) to know that there is an incoming call if the actual ring
hasn't been detected yet. How all the other PBXs work around this is
that you make sure to plug in the lines in one direction while dialing
out in the other direction. That doesn't realy get rid of the problem,
it just works around it.
In asterisk you do that by (assuming you have a 4 port FXO Digium
card, and that you have more than one line, if you only have one then
get anohter one):
1. Find out which line is always the first one for incoming in you hunt group.
2. Plug that in to the first port on the Digum card.
3. Repeat steps 1 and 2 for the next line
4. Set up your zapata.conf to have channel 1-4 as one group.
5. In extensions.conf make sure that you use dial(zap/G1) and not
dial(zap/g1) that will make sure that it always tries 4 first.
