[asterisk-users] International dialplans for Asterisk?

[Henry.L.Coleman]

The + sign is grammatic only it just means your international dialing prefix
"+" the country code ....etc.
So for dialing a number from Canada to the UK you would advertize the
number as + 44 xxxx xxxxxx etc. In Canada we dial "011" for international
calls so I would actually dial 01144 xxxxxxxxxxx etc.
