asterisk users - Sep 2005 - To get phone to ring in two or more places

Couldn't find this anyplace so here's the magic
trick:

If you want to get a phone number to ring in 2
places or multiple places, set up a ring group
with all the extensions that you want to ring.
Then in "Inbound Routing", "Set Destination"
should point to the new ring group.

Now, if after confirming the changes, and restarting
Asterisk, the phones don't ring, try the following

For each extension, set:

qualify = yes

then confirm the changes, restart Asterisk, reboot
the SIP boxes (or SIP phones),

Check to see if it works.  If not, perhaps restart
Asterisk again (restart when convenient)
