Hi all,

I set up ser + asterisk.
Asterisk is registred as gateway at home.net and listen
port  5070 (same box).
two hard phones are registred as bob at home.net and
alice at home.net .

from alice or bob i want to call 01013 to PSTN without
success.
ser lookup location and aliases and so reply not found
thought i set forward ?

Thanks for your help
Harry
