picabotwo,
The difficulty in your question is that your limited data sample requires us to assume a lot. The following works with the data provided. 
#!/usr/bin/perl
use constant MAX_OPEN_CALLS => 100;
use strict;
use warnings;

my $log = $ARGV[0] or die "Usage: $0 <log_file>";
open(my $fh, '<', $log) or die "Unable to open '$log' for reading: $!"
+;

my %call;

{
    local $/ = '==============================================';
    while (<$fh>) {
        my ($type, $id, $info) = parse_rec($_);
        if ($type eq 'INIT') {
            next if $info !~ /TCH/;
            die "Multiple calls with id '$id' without response" if exi
+sts $call{$id};
            $call{$id} = undef;
        }
        elsif ($type eq 'RESPONSE') {
            next if ! exists $call{$id};
            print "Call with id '$id' has a Px,Py of '$info'\n";
            delete $call{$id};
        }        
        die "Too many unanswered calls" if keys %call > MAX_OPEN_CALLS
+;
    }
}

sub parse_rec {
    my ($rec)   = @_;
    my ($type)  = $rec =~ /CALL_(\w+)/;
    $type       = '' if ! defined $type;
    my ($id)    = $rec =~ /TRAN_ID\s+(\S+)/;
    my $info;
    if ($type eq 'INIT') {
        ($info) = $rec =~ /CHAN_TYPE\s+(\S+)/;
    }
    elsif ($type eq 'RESPONSE') {
        ($info) = $rec =~ /Px,Py\s*=\s*(\S+)/;
    }
    $info       = '' if ! defined $info;
    return ($type, $id, $info);
}
