Guys thank you very much for all your answers. It is a very educational
process writing and reading from the users list.
For new people in kamailio like myself , the users list is the best way to
learn AFTER reading the official documentation.
Thank you once again
P.S. For the records I'm attaching the script i wrote to implement the
portability
Cheers
Alex
The scenario is that we expect calls from customers which we route through a
special prefix that they are sending us. For some customers we terminate
ported numbers and for others not.That depends on the contract they have.
Anyway the script which i will test heavily tomorrow:
>From the prefix to domain translation i expect back a value string with 4
numbers separated from dot's .
10.1.1.5
number called 1001 210XXXXXXX 1001=cust prefix and 210XXXXXX number
$var(dial_grp) = 10 the dialplan group in the dialplan query next one.values
.0-100
$var(check_p) = 1 if we want to check number for portability . values 0-1
$var(term_p) = 1 if the number is ported if we want to terminate it anyway.
values 0-1
$var(num_pr) = 4 this is the prefix(number of digits we want to remove
before the checking of portability)
if(prefix2domain("2", "0")) {
$var(dial_grp) = $(rd{s.select,0,.}{s.int});
$var(check_p) = $(rd{s.select,1,.}{s.int});
$var(term_p) = $(rd{s.select,2,.}{s.int});
$var(num_pr) = $(rd{s.select,3,.}{s.int});
$rU = $(rU{s.substr,$var(num_pr),0}); # we cat the prefix
here
if($var(check_p)==1){
sql_query("ca", "SELECT prefix FROM ported WHERE phonenumber='$rU'",
"ra");
$rU = '' + $dbr(ra=>[0,0]) + $rU;
if($var(term_p)==0){
xlog("alx ------- We dont terminate this
ported number!!!! ----------");
sl_send_reply("503","Congestion");
exit;
}
sql_result_free("ra");
}
