[Freeswitch-users] Default maximum number of simultaneous outgoing PSTN calls

[Peter Olsson]

You probably need to contact you PSTN provider to help you out here. You can also dump the FreeTDM traffic and analyze what happens on the signalling level.

Thanks Brian,

I am generating not more than 10 calls at a time from FreeSWITCH. There is a script that reads for any new entries from database and as soon as the rows are inserted and it generates calls through event socket simultaneously to all the new numbers. I have also tried to put a sleep of 250 ms in the script generating request to event socket. Below is the piece of code that executes whenever a new row is generated:

my $dialstring = "api originate {voiceMessageID=$vmID,respreqd=$respReqd,mobnum=$mobileNum,lang=$language,ignore_early_media=true}freetdm/1/A/$mobileNum 47673501 XML public\n\n";
# initialize host and port
$socket = IO::Socket::INET->new(PeerAddr => "127.0.0.1",
PeerPort => 8021,
Proto    => "tcp",
Type     => SOCK_STREAM)
or die "Couldn't connect to 10.1.30.229:8021<http://10.1.30.229:8021> : $@\n";
print $socket "auth ClueCon\n\n\n";
$answer = <$socket>;
print $answer;
print $socket $dialstring;
$socket->recv($data,1024);
#$answer = <$socket>;
print $data;
close($socket);

How many calls are you trying to start at once?  You could just be pissing off the switch on the other side by bring up too many calls quickly.
