[Asterisk-Users] Incoming phone line rollover / hunt?

[Robert Hajime Lanning]

I am planning on getting 4 analog "trunk" lines from my carrier (SBC).
~US$14/month/each
And a block of 20 DID numbers for these trunk lines.
(~US$15/month/block of 20)  (a block of 20 is the smallest)

Inbound calls come in, and the lines (on the * side) are set to the
same context.  (which contain the DID extensions)

If you are not going to use DID, the lines still come into the same
context, just you do not handle the DID extensions.  You would just
answer and provide a menu of some sort.

The rollover feature is really just "busy call forwarding".

You can buy 4 residential lines.  (do not get call waiting)
Setup "busy call forwarding":
1 -> 2
2 -> 3
3 -> 4

Then advertise the number for line 1.

Outbound calls would be handled by the "group" feature of Zapata.
You put the 4 lines in the same group (in zapata.conf) and the
extension.conf would have Dial(Zap/g<groupnumber>/${EXTEN})
