[asterisk-users] problems to call brazil from germany

[Sebastian Reitenbach]

Hi,

my problem in short:

I have a problem reaching a co-worker with the asterisk calling from Germany 
to Brazil. With a chance of about 90% I get a "chanunavail" message from the 
asterisk. Normally I try calling him in the afternoon Germany, when he is 
awake in Brazil.

so I tried to make calls to Brazil from Germany via the Asterisk telephone 
system in the morning, then everything is most likely fine (tried some numbers 
I found via google) when I do this in the afternoon then I get most likely 
a "all channels unavalable". When I get the all channels unavalable message, 
then try to call the same number from a mobile, it can reach the number 
without problem.

my theory: I use a cheap preselected carrier to call out via the asterisk, 
that one has not much overseas lines, and therefore they are getting exhausted 
at the afternoon, when there are the people up in Brazil.
when calling at the same time from a mobile phone, then using another carrier 
that has more overseas lines and therefore I can reach the number.

I have no clue whether my theory is fine, or absolutely stupid. Its just out 
of the observations I have made so might be completely wrong.

so any idea whether my theory is right or not, and if not, any other theories?

hope its more clear now.

kind regards
Sebastian
