I notice the number you Dial()led didn't start with a zero.

Check with your telco about this if you like but you almost certainly need to 
include the initial 0 of the STD code when using an analogue exchange line, 
because a TDM410P simply emulates standard subscriber's apparatus.

Basically, your Asterisk box is just a subscriber dialling out on a POTS 
phone; and it has to do exactly what a person with a cheap phone would do.  
That is, the STD code  (including initial 0)  and subscriber's number for 
someone in a different town; or just the number for a call to someone in the 
same town  (though dialling the code for a local call won't break anything).  
For IDD you need to dial 00, wait awhile, then the code for the destination 
country, STD code *without* the initial 0  (note, some small countries don't 
use STD codes)  then subscriber's number.
