cannot place international phone calls

[maverick0815]

It seems like this is not working at present. I have no problem call nationally...but as soon as I want to make an international call, I just can't get a line. I checked the call details and there I can find some of those calls wit "No Answer". Checking my AVM Fritz!Box, where the asterisk is registered as a sipphone- none of those calls show up.
I put a "0" as a dial prefix in the Webadmin, so any international call would have to start with "000". I don't even get a message about a wrong number, so I guess the formatting is okay.
Does anyone have an idea what could cause this?

Cheers

connect to the asterisk console using

asterisk -cr

change the verbosity to something like 3 using

core set verbose 3

Dial out, and see what happens.

done,
please, check this screenshot

so there is definately something wrong with my asterisk. I hooked up a phone directly to my fritzbox and it connects international calls without a problem

Do you dial out using a sip phone connected to your core?

[maverick0815]

yes..all my phones are connected as sip-phones. Like I said, I can make national calls, cellphone-calls...no problem..international calls- no dice
