Summary:                    Repeated DTMF
Description: 
I am experiencing DTMF repetition (4 times) while using the following
setup:

Zoiper -> (SIP/rfc2833) -> 1.4.25.1 -> get_data()

This is the only way I can reproduce the problem. IAX2 will work just
fine.

Let me know if you need more info from my part.

Thanks.

Here is more info :-) to reproduce the problem; I am using rfc2833 over SIP
and dialling
an extension that calls an AGI script which performs the get_data()
function. 
The problem is with that function that returns repeated digits.


SOFTWARE:

SoftPhone: Free Zoiper
Asterisk release: 1.4.25.1

DIALPLAN:

[test]
exten => _*7999,1,Agi(test.agi)

TEST.AGI:

#!/usr/bin/perl
use Asterisk::AGI;
$AGI = new Asterisk::AGI;
my %input = $AGI->ReadParse();
exit unless $input{'request'};
$SIG{HUP}  = 'ignore_hup';

my $user = $AGI->get_data('dir-welcome', 6000, 6);

1;

SIP_BUDDIES:

mysql> select * from sip_buddies where name=281827\G;

          host: dynamic
        apptag: 0
        lastms: 0
1 row in set (0.00 sec)

ACTION:

1- Dial *7999 from Zoiper.
2- Hear the welcome prompt message
3- Press 1 digit on zoiper dialpad (e.g. '3')

RESULT:

->  So it seems that when pressing 1 digits, 4 are taken into account.
