SETUP_ACK Workaround
Problem
A customer using NI1 was getting "SETUP_ACK" messages after dialing certain
international numbers.
Solution
Add a "#" at the end of the phone number. This is a universal way to mark the
end of a phone number.
Technical Details
SETUP_ACK is the way a switch asks, "I got the first digits you sent, where are
the rest?" With international phone numbers of variable length, the switch is
not sure that you sent a full phone number, so it asks if you have more to send.
By putting a "#" sign at the end, the switch is assured that you have sent a full
phone number. This is not a problem on fixed-length phone numbers, such as domestic
calls or calls to countries with fixed length phone numbers.
Tip
This works on all regular telephones, too. When dialing international numbers,
your calls complete much faster if you press the "#" key after dialing.
