[asterisk-users] Outbound FXO call, getting "You must first dial..."

[Nick Ellson]

I did have a bit of trouble with searching (what to search on), though 
looking for the w in the dial command did return quite a few hits as you 
described. Thank you so much for taking the time to reanswer a covered 
subject.

I played with the settings and 1 w and removing the :1 after EXTEN (not 
stripping the leading digit?) makes it reliable. Not stripping the first 
digit worked about 2 in 5 attempts. I stumbled onto that idea when I 
missdialed a number "921503<7 digit number>" and it worked! The 2 was a 
fat finger mistake. So I tried "90xxxxxxxxxx" and that worked.

As I have some success now, I can tune this so it works as the HowTo's 
list. :)

Thank you again!
